#include
#include
using namespace std;
class complex{
double re, im;
public:
complex() : re(1),im(0.4) {}
complex operator+(complex &t);
void Print() { cout << re << " " << im; }
};
complex complex::operator+ (complex &t){
complex temp;
temp.re = this?>re + t.re;

What happens when you attempt to compile and run the following code?
#include
using namespace std;
namespace myNamespace1
{
int x = 5;
int y = 10;
}
namespace myNamespace2

}
int main () {
{
using namespace myNamespace1;
cout << x << " ";
