No because they are not Standard C functions but I bet if you take the
time to look them up yourself in your system documentation (or google,
etc.) you can figure it out.

and also wat is the diff between return(); & return(0); &
return(1);..... .....

"return();" is a syntax error (hint: return is not a function),
"return(0); " returns the value 0 from the current function,
"return(1); " returns the value 1 from the current function. Hope that
helps.

The latter doesn't exist in Standard C?

Illegal (no expression in the ()).

& return(0);

Verbose form of `return 0;`.

&
return(1);..... .....

Verbose form of `return 1;`.

In `main`, `return 0;` means roughly "exit successfully" and
`return 1;` means "exit in a way the C standard does not
specify and hence is as portable as a baby elephant wearing
iron boots and a depleted-uranium flak-jacket".

Neither does the former.

Robert Gamble points out that getch doesn't either. Bad me.
Sloppy. No biscuit.

Nice sig, but are you certain that you've got enough significant
digits?

Since neither is a standard function, you need to check the
documentation where they are provided.

return is not a function. It is a statement. return() is a syntax
error. The other two simply return different values to the calling
function. If they appear in main, return 0 has special meaning
(equivalent to EXIT_SUCCESS) while return 1 is not portable.
