What happens when you attempt to compile and run the following code?

#include <iostream>
using namespace std;

class complex{

double re;

double im;

public:

complex() : re(0),im(0) {}

complex(double x) { re=x,im=x;};

complex(double x,double y) { re=x,im=y;}

void print() { cout << re << " " << im;}

};

int main(){

complex c1;

double i=2;

c1 = i;

c1.print();

return 0;

}
