what is int main() ???


C programs contain one or more functions, exactly one of which must be main
Parenthesis used to indicate a function
int means that main "returns" an integer value
Braces ({ and }) indicate a block
The bodies of all functions must be contained in braces
 
Example:
#include <stdio.h>

int main()
{ // block start

    printf("Welcome To Huzaifa's Blog\n");

    return 0 ; // return an integar value i.e 0

} // block end
