You'll be surprised if you try it Dave....
int AddTwoInts (int& a, int& b)
{
int x = a;
int y = b;
a = 6; // Note this line
return x + y;
}
int main()
{
int32_t m=4;
gint n=5;
AddTwoInts ((int&)m, n);
return 0; // 'm' equals 6 by the time you get to this line !!
}
I was surprised too - but it works (!?!)
