In this tutorial, you will learn to write a program to check whether a character is a vowel or constant using if-else. Here, we are using examples, and algorithms with fully explained programs for your better understanding of this problem. This topic is also suited for checking whether an input character is a vowel or consonant in the C program using if-else.Problem StatementWe have to Write a C program that checks whether a given character is a vowel or a consonant. Our program should take a character as input and after checking they should spring a character as a vowel or consonant.ExampleEnter a character: AOutput: The character A is a vowel.Enter a character: ZOutput: The character Z is a consonant.Algorithm to Check Character Is A Vowel Or Consonant Using If-else- Start the program.- Declare a variable character of type char to store the input character.- Prompt the user to enter a character by printing the message "Enter a character: ".- Read the input character from the user and store it in the character variable using scanf().- Convert the character to uppercase using the toupper() function to handle lowercase inputs.- Use an if-else statement to check if the input character is a vowel or a consonant:- If character is equal to 'A', 'E', 'I', 'O', or 'U', print the message "The character is a vowel."- Otherwise, print the message "The character is a consonant."- End the program.C Program to check whether a character is a vowel or consonant #include #include int main() { char character; printf("Enter a character: "); scanf(" %c", &character); character = toupper(character); if (character == 'A' || character == 'E' || character == 'I' || character == 'O' || character == 'U') { printf("The character %c is a vowel.n", character); } else { printf("The character %c is a consonant.n", character); } return 0;}Output 1Enter a character: AThe character A is a vowelOutput 2Enter a character: SThe character S is a consonantProgram Explanation- The program starts by including the necessary header files: stdio.h for input/output functions and ctype.h for character handling functions.- The main() the function is defined.- Inside the main() function, a variable character of type char is declared to store the input character.- The program prompts the user to enter a character by printing the message "Enter a character: ".- The scanf() function is used to read a character from the user, and the input is stored in the character variable using the %c format specifier. A space is added before %c in scanf to consume any leading whitespace or newline characters from the previous input.- The toupper() function is used to convert the input character to uppercase to handle lowercase inputs.- An if-else statement is used to check if the input character is a vowel or a consonant:- If the input character is 'A', 'E', 'I', 'O', or 'U', the program prints the message "The character is a vowel." The %c format specifier is used in printf() to print the character.- If the input character is not one of the vowels, the program prints the message "The character is a consonant."- The return 0 statement ends the program.ConclusionThis C program allows the user to enter a character and determines whether it is a vowel or a consonant using if-else statements. It covers all possible cases and provides the appropriate output based on the input character.

IntroductionIn this tutorial, you will learn how to write a C program to print the maximum among three numbers by using if-else statement. We have also explained some examples, algorithm, and programs for your better understanding. Problem StatementWrite a C program that reads three numbers from the user. After taking the inputs it should determine the maximum among them using the "if-else" statement. The program should display the maximum number as output.ExampleEnter the first number: 8Enter the second number: 12Enter the third number: 15The maximum number is 15In the above example 15 is printed as an output means it is a greatest among other (8, 12). So Here the Output will be 15 and it is correct.Algorithm- Start the program.- Read the first number and store it in a variable, let's say num1.- Read the second number and store it in another variable, let's say num2.- Read the third number and store it in a third variable, let's say num3.- Compare num1, num2, and num3 using the "if-else" statement: a. If num1 is greater than both num2 and num3, print num1 as the maximum number. b. If num2 is greater than both num1 and num3, print num2 as the maximum number. c. Otherwise, print num3 as the maximum number.- End the program.Program To Print Maximum Among Three Numbers#include int main() { int num1, num2, num3; printf("Enter the first number: "); scanf("%d", &num1); printf("Enter the second number: "); scanf("%d", &num2); printf("Enter the third number: "); scanf("%d", &num3); if (num1 > num2 && num1 > num3) { printf("The maximum number is %d.n", num1); } else if (num2 > num1 && num2 > num3) { printf("The maximum number is %d.n", num2); } else { printf("The maximum number is %d.n", num3); } return 0;}OutputEnter the first number: 65Enter the second number: 23Enter the third number: 45The maximum number is 65Program Explanation- We start by including the necessary header file stdio.h for input/output operations.- The main() function is the entry point of the program.- We declare three variables num1, num2, and num3 to store the input numbers.- We prompt the user to enter the first number using printf().- The scanf() function is used to read the first number and store it in the variable num1.- We repeat steps 4 and 5 for the second and third numbers.- Using the "if-else" statement, we compare num1, num2, and num3.- If num1 is greater than both num2 and num3, we print num1 as the maximum number.- If num2 is greater than both num1 and num3, we print num2 as the maximum number.- Otherwise, we print num3 as the maximum number.- Finally, the program ends and returns 0 to the operating system.ConclusionIn conclusion, the C program we developed successfully solves the problem of finding the maximum among three numbers using the if-else statement. It allows the user to input three numbers, compares them, and displays the maximum number as the output. The program demonstrates the use of conditional statements and input/output operations in C programming. By understanding this program, you have gained knowledge of how to make decisions based on conditions and perform basic input/output operations in C.

In this tutorial, we are going to learn to write C Program to check whether a given number is divisible by 5 or not. As we know that a number is divisible by 5 when 0 or 5 is at its unit digit. Below, we have written and explained the writing program for how to check the divisibility of a number by 5 with the help of an if-else statement in c.Problem StatementWe need to check that a given input number by users is divisible by 5 or not by using if-else statements. Here Our program will take integer input from the user. It should print “the given number is divisible by 5” in case of number is divisible by 5. And if the number is not divisible by 5 then it should print “number is not divisible by 5”.For ExampleEnter a number: 15The number 15 is divisible by 5.In the above example you can see given input is 15. As 15 is divided by 5, So the output here is "The number 15 is divisible by 5".Program to Check a Given Number is Divisible by 5 or not in C#includeint main(){ int num; printf("Enter a number: "); scanf("%d", &num); if(num % 5 == 0) { printf("The given number is divisible by 5"); } else { printf("The given number is not divisible by 5"); } return 0;}Output 1:Input :Enter a number: 25Output:The given number is divisible by 5Output 2:Input :Enter a number: 23Output:The given number is not divisible by 5Program Explanation:Let's go through the program step by step to understand it better:- We have included stdio.h to enable the program to do input and output operations.- The main() function is the entry point of any C program.- Here, we have declared the variable 'num' of integer type to store user input.- printf() function is used to show the output/message on the display.- scanf() function is used to read the input given by the user.- if-else statement is used to apply check whether the given integer input is divisible by 5 or not.- The % is known as the percentile operator, used to find the remainder when a number is divided by the divisor.- In our scenario,when we divide a number by 5 and if the remainder is zero, it means that the number is divisible by 5. Otherwise, the program displays the message not divisible by 5.- The return statement returns 0 to the operating system and denotes the end of a program.ConclusionIn this tutorial, we have learned to write a C program to check whether a given number is divisible by 5 or not with the help of if-else statements. The above program takes an integer as input from the user. And After taking input, with the help of if else statement it checks whether the number is divisible by 5 or not. I hope this blog was helpful to you in understanding the C program.

In the other case, it will print "The input is not an alphabet".ExampleEnter a character: T Output: The input is an alphabet.Enter a character: 5 Output: The input is not an alphabet.Algorithm- Declare a variable input of type char to store the user input.- Display a prompt asking the user to enter a character.- Read the character entered by the user and store it in the input variable.- Use an if-else statement to check if input falls within the range of lowercase letters 'a' to 'z' or uppercase letters 'A' to 'Z'.- If the condition is true, print "The input is an alphabet."- If the condition is false, print "The input is not an alphabet."- Return 0 to indicate successful execution of the program.Program to check whether a given input is an alphabet or not #include int main() { char input; printf("Enter a character: "); scanf("%c", &input); if ((input >= 'a' && input = 'A' && input= 'a' && input = 'A' && input

In this tutorial, we are going to learn to write C Program to check whether a given number is divisible by 11 or not.Any number where the difference between the sum of digits at odd and even places is 0 or a multiple of 11 is divisible by 11.Below, we have written and explained the program for how to check the divisibility of a number by 11 with the help of an if-else statement in C.Problem StatementWe need to check that a given input number by users is divisible by 11 or not by using if-else statements. Here Our program will take integer input from the user. It should print “the given number is divisible by 11” in case of number is divisible by 11. And if the number is not divisible by 11 then it should print “number is not divisible by 11”.For ExampleExample 1:Suppose we have to check 82907 is divisible by 11 or not?Sum of digits at odd place = S1 = 22 (8+9+7)Sum of digits at even place = S2 = 2 (2+0)S1-S2 = 22-2 = 22 (multiple of 11) so we can say 82907 is divisible by 11.The above example is showing how you can check quickly if you don't have a calculator. But for writing the program that logic is completed.We can easily Check by using % operator in C.Program to Check Divisibility by 11#includeint main() { int num; printf("Enter a number: "); scanf("%d", & num); if (num % 11 == 0) printf("Yes, %d is divisible by 11.", num); else printf("No, %d is not divisible by 11.", num); return 0;}Program OutputOutput 1:Enter a number: 123No, 123 is not divisible by 11.Output 2:Enter a number: 121Yes, 121 is divisible by 11.Program Explanation- Let's go through the program step by step to understand it better:- We have included stdio.h to enable the program to do input and output operations.- The main() function is the entry point of any C program.- Here, we have declared the variable 'num' of integer type to store user input.- printf() function is used to show the output/message on the display.- scanf() function is used to read the input given by the user.- if-else statement is used to apply to check whether the given integer input is divisible by 11 or not.- The % is known as the percentile operator, used to find the remainder when a number is divided by the divisor.- In our scenario, when we divide a number by 11, and if the remainder is zero, it means that the number is divisible by 11. Otherwise, the program displays the message not divisible by 11.- The return statement returns 0 to the operating system and denotes the end of a program.ConclusionIn this tutorial we have learnt to write C program to check whether a given number is divisible by 11 or not with the help of if-else statements. The above program takes a integer as input from the user. And After taking input, with the help of if else statement it checks whether the number is divisible by 11 or not.

In this tutorial, we are going to write a C Program to check whether a given number is odd or even number.Any number which is when divided by 2 gives 0 as its remainder is called an even number. Whereas, odd numbers leave 1 as the remainder when divided by 2.Problem statement:We need to check if any number is even or odd, by using if-else statements. Here our program will take integer input from the user at runtime.It should print "Even Number" in case the number is even. And if the number is odd it shoud print "Odd Number".Program to Check Given Number is Even Or Odd In C#include int main(){ int num; printf("Enter a number: "); scanf("%d", &num); if(num % 2 == 0) { printf("%d is Even Number", num); } else { printf("%d is Odd Number", num); } return 0;}Example 1:Input: 10 Output: Even NumberExample 2:Input: 15 Output: Even NumberProgram ExplanationLet's go through the program step by step to understand it better:We have included stdio.h to enable the program to do input and output operations.The main() function is the entry point of any C program.Here, we have declared the variable 'num' of integer type to store user input.printf() function is used to show the output/message on the display.scanf() function is used to read the input given by the user.The % is known as the percentile operator, used to find the remainder when a number is divided by 2.Inside the if statement we check whether the remainder of 'num' when being divided by 2 is equal to 0 or not.If it divides completely, then the program prints "Even Number", else it prints "Odd Number".The return statement returns 0 to the operating system and denotes the end of a program.ConclusionWe have learned to write a C program to check whether a given number is odd or even. We have used conditional if-else statements to achieve this.I hope this blog was helpful to you in understanding the C program.

In this program, you will learn how to write a C program to check whether a given number is a positive number or a negative number. Let's understand this problem with some examples and algorithms.Problem StatementOur problem statement is you have to write a C program that takes a number as input and checks whether it is positive or negative. Below is an example for a better understanding.Examples:Enter a number: 5Output: The number is positive.Enter a number: -7Output: The number is negative.Algorithm- Start the program.- Declare a variable number of type int to store the input number.- Print a message asking the user to enter a number.- Read the input number using scanf and store it in the number variable.- Use if-else statements to check the sign of the number:- If number is greater than 0, print "The number is positive."- Else if number is less than 0, print "The number is negative."- Else, print "The number is zero."- End the program.Program to check whether a given number is a positive or negative number#include int main() { int number; printf("Enter a number: "); scanf("%d", &number); if (number > 0) { printf("The number is positive.n"); } else if (number < 0) { printf("The number is negative.n"); } else { printf("The number is zero.n"); } return 0;}Output 1Enter a number: 44The number is positiveOutput 2Enter a number: -44The number is negativeProgram Explanation- The program starts by including the necessary header file stdio.h.- The main() function is defined.- Inside the main() function, a variable number of type int is declared to store the user's input.- The program prompts the user to enter a number by printing the message "Enter a number: ".- The scanf() function is used to read an integer from the user, and the input is stored in the number variable using the & operator.- The program checks the sign of the number using if-else statements:- The first if statement checks if the number is greater than 0. If true, it prints "The number is positive."- The else if statement checks if the number is less than 0. If true, it prints "The number is negative."- If none of the above conditions are satisfied, the else statement executes and prints "The number is zero."- The return 0 statement ends the program.ConclusionThis C program allows the user to enter a number and determines whether it is positive, negative, or zero using if-else statements. It covers all possible cases and provides the appropriate output based on the input.
