return value

[magnificence7]

If you have a function that returns a value, and you use that function like:
int i = function();
Will the value that is returned be copied to int i, or will only the reference of int i be changed to the point where the return value is in the memory?

If so, if you return an array value that is huge, like:

vector<int> function()
{
    vector<int> vi;
    //some code here to create a huge huge vector..., like 1,000,000 items
    return vi;
}

Will then the whole vector be copied to the variable where you want to give it to, or not, as I asked above.
