Function can be used in C

C programs require function calls to library functions to print anything on the screen as the output of the program. It requires connecting the iostream.h for the purpose. Mostly we use the header file "stdio.h" 

#include<stdio.h>

To call a set of library functions for the standard input and output. These beginning the program with the above line, call the printf () function from the main () or any other function to direct the a sequence of characters to a standard output. Try the following.

int main(){

printf("My name is XYZ");

return(0);

}

Thus you get an output 

My name is XYZ.

The syntax of printf function is given below.

printf("sequence of characters & %format specifiers", parameters);

Parameters and format specifiers are optional. We have just specified the sequence of characters in the above program.
