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:

int main()
{ // block start

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

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

} // block end
