C Programming Language Is Considered As The Base For Other Programming Languages, That Is Why The Reason C Programming Language Is Called As " Mother Language ".

C Programming Language Is Also Known As

System Programming Language Procedure Oriented Programming Language Structural Programming Language Mid-Level Programming Language  

Features Of C Language 

C Programming Language Is Widely Used Language. It Provides A Lot Of Features Like Simple Machine Independent Mid-level programming Structural Programming Language Rich Library Memory Management Fast Speed Pointers Recursion Extensible  

Header Files

A Header File Is A File With Extension.h Which Contains C Function Declarations And Macro Definitions  To Be Shared In Between Several Source Files.   #include It Includes The Standard input And Output Library Functions. print f() And scan f() Are Defined In stdio.h.   #include It Includes Console Input & Output Library Functions. getch() and clrscr() fuctions are defined in conio.h file. getch() the gech() function asks for a single character. until we press any key it blocks the screen. clrscr() if we run the c program many times the previous outputs will appear.to clear the screen and to erase the previous output we use clrscr() function to clear the screen.so it will be better for us to call clrscr() after the main method.  

print f()

It Is Used For Output It Prints The Given Statement To The Console.       Syntax  printf("format string,arguments"); The Format String Can Be %d(Integer) %f(float) %c(charecter) %ld(long charecter) %s(string) Etc.  

scanf()

It Is Used To Read The Input Data From The Console.  Syntax scanf("format string",& arguments);    

void main()

" void " Returns No Value. The Main Function Is The Entry Point For Every C Program. The " void " Keyword Specifies That It Returns No Value.     So, include And include Are Header Files.printf() scanf() void main()Are The fuctions used In Writing a C Program.
