Passing array by reference

Hi. I'm stuck on something that seems quite simple: passing an array by reference. I've attached a skeleton version of the code which gets the idea across. Array num[2] is passed to process_day but process_day can't see the values in the array.

What am i missing here?

So, is this C or C++
Because there's some of each in there.
I'm going with C++

From header.h, remove
#include <stdio.h>

From process_day, delete these 2 lines
> int a[2];

> int b;

And use cout instead of printf()

In main
> process_day(&num[2], num2);
Should be
process_day(num, num2);
But num2 is neither initialised or used, so it can be removed as a parameter.

Awesome, thanks for the quick response.

I learned C back in college 15 years ago but the compiler i'm using, Dev-C++ is defaulted to C++...thus the mixing. The message boards and online tutorials seem to indicate this is acceptable, you agree?

arrays are ALWAYS passed by reference. all you have to do is place the name of the array in the parameter list, without the '&' reference operator.

I personally don't care whether you use C or C++.
But I would suggest you make a clean choice rather than some random hybrid which randomly mixes both.

You can make dev-c++ default to C if you want it to.
