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

#include

#include

using namespace std;

class complex{

double re, im;

public:

complex() : re(1),im(0.3) {}

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

complex(int m,int n) { re=m,im=n;}

complex operator+(complex &t);

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

};

complex complex::operator+ (complex &t){

complex temp;

temp.re = this?>re + t.re;

temp.im = this?>im + t.im;

return temp;

}

int main(){

complex c1(1),c2(2),c3;

c3 = c1 + c2;

c3.Print();

}

What will the variable "y" be in class B?

class A {

int x;

protected:

int y;

public:

int age;

};

class B : private A {

string name;

public:

void Print() {

cout << name << age;

}

};

If there is one, point out an error in the program

#include

using namespace std;

int main()

{

int i=1;

for(;;)

{

cout<

if(i>5)

break;

}

return 0;

}

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

#include

using namespace std;

int op(int x, int y);

float op(int x, float y);

int main()

{

int i=1, j=2, k;

float f=0.3;

k = op(i, j);

cout<< k << "," << op(0, f);

return 0;

}

int op(int x, int y)

{

return x+y;

}

float op(int x, float y)

{

return x?y;

}

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

#include

using namespace std;

int main(){

int i = 1;

if (--i==1) {

cout << i;

} else {

cout << i-1;

}

return 0;

}

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

#include

#include

using namespace std;

int fun(int);

int main()

{

int *x = new int;

*x=10;

cout << fun(*x);

return 0;

}

int fun(int i)

{

return i*i;

}

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

#include

using namespace std;

int fun(int x);

int main() {

cout << fun(0);

return 0;

}

int fun(int x) {

if(x > 0)

return fun(x-1);

else

return 100;

}
