What is the output of the following program?

#include <iostream>
using namespace std;
int x;
void summer(int&, int);
void fall(int, int&);

int main()
{
int intNum1 = 2;
int intNum2 = 5;
x = 6;

summer(intNum1, intNum2);
cout << intNum1 << " " << intNum2 << " " << x << endl;

fall(intNum1, intNum2);
cout << intNum1 << " " << intNum2 << " " << x << endl;
return 0;
}
void summer(int& a, int b)
{
int intNum1;
intNum1 = b + 12;
a = 2 * b + 5;
b = intNum1 + 4;
}
void fall(int u, int& v)
{
int intNum2;
intNum2= x;
v = intNum2 * 4;
x = u - v;

}
