Consider the following program:

#include
using namespace std;
void func1();
void func2();
int main()
{
int num;
cout << "Enter 1 or 2: ";
cin >> num;
cout << endl;
cout << "Take ";
if (num == 1) func1();
else if (num == 2) func2();
else cout << "Invalid input. You must enter a 1 or 2" << endl;
return 0;
}
void func1()
{
cout << "Programming I." < }
void func2()
{
cout << "Programming II." < }

1. What is the output if the input is 1?
2. What is the output if the input is 2?
3. What is the output if the input is 3?
4. What is the output if the input is -1?
