Introduction to Structures in C

What are Structures in C? Structures came into effect when we wanted to implement two or many data types in a kind of group fashion like (an array of different types placed together.). Structures are nothing but user defined type in c where we can combine a various data types to create a specific type of data. A structure is used in storing complex data in a ordered and structured fashion. The…

Introduction to Pointers in C

What are Pointers? Pointers is a Data Structures provided by C which gives very huge increase in speed while computing in run time. Some tasks become very easy when compared to without using pointes and some tasks can’t be done without them like dynamic memory allocation etc. POINTERS are nothing but the value of the address of a variable. We all know that every memory location and every memory…

First Largest and Second Largest Integers in an Array

In this article we are going to calculate the first and second largest element in an array using functions in c Input Format: We will be first asking the user about the input of number of elements in an array. Then we will be asking the number of  inputs for the array 1 Then we will pass through a function which calculates the first and second largest elements in the array. First and Second…

Intersection of two sets in C

Intersection of two sets in C In this article we are going to write a program which calculates the intersection of two sets . Intersection of two sets A1 ∩ A2 = is the set of elements which are both in A1 and A2 . For example: A1 = {1,52,34,534,2} and A2 = {33,23,34,3} , therefore A1∩ A2 = {10,23} Now see the representation of intersection of three sets in venn diagram of the following sets…

Union of two sets in C

Simple Calculator(Prefix Notation) Function in C,C++ In this article we are going to write a function which calculates the union of two sets . We are passing two parameters which are two arrays having unique elements (integers) and also their lengths. Union of two sets A1 U A2 = is the set of elements which are either in A1 or A2 or in both. For example: A1 = {1,52,34,534,2} and A2 =…

Sum of Prime Digits of a Number – Recursion

Sum of Prime Digits of a Number through a Recursive Function In this article we are going to learn how to write a recursive function which calculates the sum of all prime digits in a number. Input: Take a number as a  user input and then serve this number as a parameter to a recursive function which calculates the sum of all prime digits present in a number. Recursive Function to calculate the…

Scientific Calculator in C,C++(prefix notation)

Simple Calculator(Prefix Notation) Function in C,C++ In this article we are going to learn how to build an upgraded calculator which takes the inputs in a prefix notation and then computes the answers and answers the queries like log base 2, modulo ,square, square root supported with basic arithmetic operations. And the values of division are made floor of the output (25/2=12),output of the…
