You work with it using its name, which is f.

ahura24,

do you mean something like:

#include <iostream>
#include <cassert>
#include <cstdarg>
using namespace std;

int max(unsigned count, ...)
{
    assert(count > 0);
   
    va_list arguments;
    
    va_start(arguments, count);

    int result = va_arg(arguments, int);
    
    while(--count > 0)
    {
        int arg = va_arg(arguments, int);
        if (arg > result)
            result = arg;
    }
    
    va_end(arguments);

    return result;
}


int main() 
{
    int a(56), b(8), c(66),d(14);
    cout << max(4 /*number of parameters passed */, a, b, c, d) <<endl;
    
    return 0;
}
