system() is a library function that makes calls to OS commands/programs. system("pause") calls the "pause" command in DOS/Windows. Run the pause command in a command shell to see what it does.

Saying something like "it's a command saying "NOTHING TO DO" is WRONG!!! Have you ever checked the return value of the fopen() function and what it potentially means? If you assumed that the return value of this function means "nothing to do", then you may be in for a rude shock.
It's been a month since I began participating in this forum and I cannot believe some of the misnomers that are put forward.
Sheesh!!!

In case of main function, if i forgot to write return 0; at the last, GCC compiler generates no error , what i found is that.
So I said that return 0; means nothing to do.
I know about the importance of return statement in other built-in functions and user defined functions.
But in case of main function if return 1; or other would have some meaningful sense, but return 0; has no sense.

Coding in C takes more work because the compiler does not try to protect you from every possible mistake.•

If you compile with std=c99, you can omit the return statement because C99 implicitly returns 0 if execution falls off the end of main without an explicit return statement. Otherwise,
return 0; is a very good idea. If it still makes no sense to you, try return EXIT_SUCCESS; and include <stdlib.h>. That might look like more work is being done.
