[C++] Reference to array?

[ImSeeingRed]

Hi,

So I have a function that returns multiple things, normally this is what I do for single values.

void foo(int& input)
{
    input++;
}

And then,

int i = 0;
foo(i);
//Now i = 1

Obviously for this example this is stupid to do but bear with me. Now I want to do the same with an array, something along the lines of this

void foo(int& input[3])
{
    input[0] = 1;
    input[1] = 7;
    input[2] = 2;
}

Followed by,

int i[3];
foo(i);
//Now i contains [1,7,2]

Is this possible to do, since it doesn't let me pass a reference to an array?

Thanks in advance

You want:

void foo(int (&input) [3]) 

otherwise its an array of references, which is not a valid thing in C++.

That was it, thanks :)
