Does C support a variable number of arguments to pass to a function.
For instance
Function (a, b, c);
another time it's called as:
Function (z, q);

It's quite similar to - for instance - printf (however, without a format string).
Note: I don't want to pass an array of ints and don't want to copy lots of ints into the array prior to use it for the call.

Can't do it without a format string. To do it with a format string, check "The C Programming Language" 2nd edition page 155-156.

Yes, C supports variable number of arguements. You need to include the stdarg.h header and use the variables va_start, va_arg and va_end(or stop, I dont remember).

Read K&R.

YES, U CAN DO. FOR THIS YOU HAVE TO DECLARE FUNCTION LIKE THIS:-
FOO(...);

THEN USE va_start, va_list, va_arg defined in stdarg.h while implementing this function.
