Num File Name Description

1 swapref.cpp Write a function that will swap two integers values using

pass by reference ( i.e. alias) parameters.

Write a driver program to test your function.

2 check.cpp Write a function with the following

prototype:

bool compute(int one, int two, int & sum, int & product, int & quotient);

sum will be one + two, product will be one * two, and

quotient will be one/ two provided that two is not 0. If the

quotient can be computed,( i.e. two is not 0 ) return true. If the quotient

cannot be computed,( i.e. two has a value of 0 ) return false.

Write a driver program to test both cases.

3 overload.cpp Overload 4 sum functions

int sum(int, int);

int sum(int,int,int);

int sum(int,int,int,int);

int sum(int,int,int,int,int);

each sum function should return the sum

of all of the int parameters. Write your code

so that each of the last 3 sum functions calls

the one listed before it. For example,

int sum( int,int,int,int,int) should call

the function int sum(int,int,int,int) 

Write a driver program to test all 4 functions

4 box.cpp Overload displayBox function – uses loops

Complete the program template box.cpp

Use input data of 5 ? 15 4 $

NOTE: Only one of your overloaded functions needs

the details of nested loops, the other 3 SHOULD

call the one that has the details.

NOTE: box(5) will display

xxxxx

x x

xxxxx

box(5,7,’a’) will display

xxxxx

xaaax

xxxxx

5 Write a function that has two parameters:

- an integer that is a test score

- and a second parameter that is the letter grade.

The function will place a value in the second parameter

Use the standard grading scale for A, B, C, D, F.

If the score is above 100 or below 0, a grade will not

be assigned and a return value of false will be returned.

If the score is within range, a return value of true will be

returned and the letter grade will be placed in the second parameter.

The prototype for the function is:

bool figureGrade(int, char &);

Write a main function to test the function you have written.
