What is the output of the following program?

#include <iostream>

using namespace std;

int manip(int);

int manip(int, int);

int manip(int, double);

int main()

{

int x = 2, y= 4, z;

double a = 3.1;

z = manip(x) + manip(x, y) + manip(y, a);

cout ≪ z ≪ endl;

return 0;

}

int manip(int val)

{

return val + val * 2;

}

int manip(int val1, int val2)

{

return (val1 + val2) * 2;

}

int manip(int val1, double val2)

{

return val1 * static_cast<int>(val2);

}
