Question

Please use c++ and follow the instruction, I really want to fully understand this question and I will use your code to check where I made mistake (Do not skip steps).

I have written my own code which has tons of errors, and I am so confused about this lab. I need help.

Lab 6.4 – C++ and Functions – Math Test

Critical Review A value-returning function is a function that returns a value back to the part of the program that called it. In C++, you can use value-returning functions and those that do not. y = sqrt(x);                    // value returning function printBonus(stAmount, empAmount);// function returns no value             Standard Library Functions C++ comes with a standard library of functions that have already been written for you. These functions, known as library functions, make a programmer’s job easier because they perform many of the tasks that programmers commonly need to perform. The rand Function In order to use the random function in C++, you must include <cstdlib> library. You also should provide a random seed in order to get a random sequence every time you run the program by using <ctime> library. To do this, simply add the following line to the top of your code: #include <cstdlib> #include <ctime>   Add the following statement in main before using the rand() function:      srand(static_cast<unsigned int>(time(0))); The rand() function typically returns a number between 0 and 32767. The following is how you would get a random number between 1 and 6. value = rand() % 6 + 1;

Write a program that will allow a student to enter their name and then ask them to solve 5 mathematical equations. The program should display two random numbers that are to be added, such as:

247 + 129

The program should allow the student to enter the answer. The program should then display whether the answer was right or wrong and accumulate the correct values. After the 5 questions are asked, display the student name and the number correct.

In addition to any library functions you may use, you might consider the following functions:

• A function that allows the student to enter their name.
• A function that generates two random numbers, anywhere from 1 to 500.
• A function that displays the equation and asks the user to enter their answer.
• A function that calculates the results.
• A function that displays the student name and the number right.

Your sample output might look as follows (random numbers will be different):

Enter student name: Katie<Enter>

Equation is 424 + 28

Enter the sum: 472<Enter>

Wrong

Equation is 163 + 233

Enter the sum: 396<Enter>

Right

Etc…(through 5 iterations)

Information for Katie

The number right: 3

The Pseudocode

Module main()

            //Declare local variables

            Declare Integer counter

            Declare String studentName

            Declare Integer right = 0

            Declare Integer number1

            Declare Integer number2

            Declare Integer answer

            Call srand(time(0))                                // to generate random sequence each time

            Set studentName = inputName()

            //Loop to run program again

            For counter = 1 to 5

                        //calls functions

Call generateNumbers(number1, number2)

Set answer = getAnswer(number1, number2)

                        If answer == number1 + number2 then

                                    Display “Right”

                                    Set right = right + 1

                        Else

                                    Display “Wrong”

                        End If

            End For

            Call displayInfo(right, studentName)

End Module

Function String inputName()

Declare String name

            Display “Enter student name: ”

            Input name

            Return name    

End Function

Module generateNumbers(Integer Ref number1, Integer Ref number2)

            Set number1 = rand() % 500 + 1

            Set number2 = rand() % 500 + 1

End Module

Function Integer getAnswer(Integer number1, Integer number2)

            Declare Integer answer

            Display “Equation is ”, number1, “+”, number2

            Display “Enter the sum: ”

            Input answer

            Return answer

End Function

Module displayInfo(Integer right, String studentName)

            Display “Information for ”, studentName

            Display “The number right:”, right

End Module

When your code is complete and runs properly, capture the output. Copy and paste both the source code and the output.
