Question

Need help building this C++ program

For your program you will create a class that represents square shapes. I provide you an incomplete client program that will test your class and an incomplete header file where you have to declare and implement the class.

In the client program you have to complete certain statements according to the indications provided in the corresponding comments.

In the header file you have to create class square according to the following specifications:

Member functions

// member that assigns a value to the side void setSide(int s);

// member function that returns the value of side int getSide();

// parameterized constructor with default parameter = 0 square(int s);

// member function that returns the addition of the areas of 2 squares int plus(square sq);



// member function that returns a square of side equal to the side of the square multiplied by a factor square increaseBy(int factor);

// member function that compares 2 squares for equality bool equalTo(square sq);

// member function that returns the area of the square int area();

// member function that returns the perimeter of the square int perimeter();


Data member

side: holds the side of the square (whole number)

When you declare the class you must define which members should be public and which should be private, which member functions should be const, and the data type of the data member among other things. You then have to define the member functions below the class declaration in the same file. Run my solution and pay attention to the output to determine what function is tested at each stage of it. It is your responsibility to understand the requirements specified on this handout; if you have doubts about certain aspects of the problem then you must ask the designer of the class (me) for more details. Of course, your questions should be as specific as possible. You may also consult with other programmers (classmates) through Blackboard.

Read the documentation above carefully to understand how the members of the class must be implemented and used. If you find inconsistencies or have some questions please post them on the corresponding topic of the discussion board. I will first wait for somebody to reply and then will provide my answer.

The following is a sample run of my solution processing the values from the input file provided: ___________________________________________________________________________________

Before assigning values to the squares their sides are: Square 1: 0 Square 2: 0 Square 3: 10


............Starting to process the file............

Storing the values read into the side of squares...

Displaying the new side of squares Square 1: 2 Square 2: 5 Square 3: 7

Testing other member functions

Area of Square 1: 4 Perimeter of Square 2: 20 Square 1 and Square 3 are not equal Area of (Square 2 + Square 3): 74 Creating a square double the size of Square 1 The side of the new square: 4

..........Done with this set of values :-)..........

Storing the values read into the side of squares...

Displaying the new side of squares Square 1: 3 Square 2: 2 Square 3: 1

Testing other member functions

Area of Square 1: 9 Perimeter of Square 2: 8 Square 1 and Square 3 are not equal Area of (Square 2 + Square 3): 5 Creating a square double the size of Square 1 The side of the new square: 6

..........Done with this set of values :-)..........


Storing the values read into the side of squares...

Displaying the new side of squares Square 1: 4 Square 2: 4 Square 3: 4

Testing other member functions

Area of Square 1: 16 Perimeter of Square 2: 16 Square 1 and Square 3 are equal Area of (Square 2 + Square 3): 32 Creating a square double the size of Square 1 The side of the new square: 8
