1. A function can have __________ parameters.

• a maximum of five
• only one
• zero or more
• a blank space

2. Variables defined in the body of a function that are visible only to the function are called __________ variables.

• local
• global
• function
• special

3. Vairables defined in functions whose values persist from call are called __________ variables.

• global
• static
• function
• special

4. The default manner in which passing parameters to funcitons is achieved in C++ __________ .

5. What is displayed by the following code?

#include <iostream>
using namespace std;

void func(int x, int y, int z) {
    x = y + z;
    y = 10;
    x = 20;
}

int main() {
    int a = 10, b = 20, c = 30;
    func(a, b, c);
    cout << a << " " << b << " " << c << endl;
    return 0;
}

• 80 30

6. What is displayed by the following code?

#include <iostream>
using namespace std;

void func(int &x, int &y, int &z) {
    x = y + z;
    y = 10;
    x = 20;
}

int main() {
    int a = 10, b = 20, c = 30;
