Answer Posted / vilas soni++

main() is predefined function, coz we can't change it's
prototype....
We can only implement it.... And we have to use main() in
our program coz it's "Entry Point" to any C program....

(We can say userdefined, if we can also define it's
prototype and name, and in this case we can't!, we can use
only available types of main()....)

I heard that you have to include stdio.h before calling printf. Why?
