float amount, forWaiter;
char service;

If the following function header is given:

float tip(float amountP, char serviceP)

which of the options below is a correct calling statement of the functiontip?

1. forWaiter = tip(float amount, char service);
2. tip(amountP, serviceP);
3. forWaiter = tip(123.66, 'A');
4. forWaiter = tip(amountP, serviceP);
5. None of the above options is a correct calling statement.


QUESTION 2

Suppose the following declarations appear in a C++ program:

float afford, amount;
int number;
string name;

If the following function header is given:

void supplyInfo(float affordP, int nrP, string & nameP, float & amountP)

which of the options below is a correct calling statement of the functionsupplyInfo?

1. supplyInfo(800, 4, "Beach Hotel", 789);
2. supplyInfo(800, 4, name, amount);

QUESTION 3

Suppose the following declarations appear in a C++ program:

int age, days;
char grade;
float salary;

Suppose the following calling statement appears in the program:

inputInfo(35, 'B', salary, days);

Which of the options below is a correct function header of the functioninputInfo?

1. void inputInfo(int ageP, char gradeP, float & salaryP, int & daysP)
2. void inputInfo(35, 'B', float salaryP, int daysP)
3. void inputInfo(int & age, char & grade, float & salary, int & days)
4. void inputInfo(35, 'B', salary, days)
5. All of the above options are correct function headers.


Questions 4 and 5 are based on the following C++ program.

#include <iostream>
#include <string>
using namespace std;

int main( )
{
string favour;
int tvHours, favourHours;

cout << "How many hours per week do you watch sport on TV, " << endl
<< "what is your favourite sport, how many hours for that? ";
cin >> tvHours >> favour >> favourHours;

if (tvHours > 10)
if (favour == "soccer")
{
if (favourHours > tvHours / 2)
cout << "Group A" << endl;
}
else
if (favourHours > tvHours / 4)
cout << "Group B" << endl;
else
cout << "Group C" << endl;
else
if (favour != "rugby")
cout << "Group D" << endl;

return 0;
