How many variables can be passed in the argument list of a function in C?

Question

How many parameters can we pass as argument in function? Is there any limit ?
If yes , Please explain the reason.

Answer 1

Whenever a function is declared to have an indeterminate number of arguments, in place of the last argument you should place an ellipsis (which looks like '...'), so, int a_function ( int x, ... ); would tell the compiler the function should accept however many arguments that the programmer uses, as long as it is equal to at least one, the one being the first, x.

int a_function ( int x, ... )
{
    va_list a_list;
    va_start( a_list, x );
}
