For the given test: class A1 { int x; int y; public: A1(int a, int b) { x=a; y=b; } A1 operator+(const A1&); }; A1 A1::operator+(const A1& second) { A1 sum(0,0); sum.x = x + second.x; sum.y = y + second.y; return (sum); } int main (void) { A1 one(2,3); A1 two(4,5); return 0; } when the exectable of this code is debugged in gdb for i386, we dont get the
