Question

c++

Write a program that computes and displays the tuition for courses offered at the University. First, the program should ask if the student has registered for a regular course or a course with a lab component. The user can enter the letter 'C' or 'c' for lecture course only, or the letter 'L' or 'l' for a laboratory course . Write a function called Menu, which takes no input parameters and returns a char value. Your main program will call this Menu function, which will prompt the user to enter the category ('c'or 'C' for lecture course only or 'l'or 'L' for lecture + lab course) and return the char entered by the user to your main program. For the lab course option, the total of lecture hours and lab hours is limited to 4.

Next in the main program, use the switch statement to get additional information from the user and compute the tuition.

For the course only option, ask the user to enter the following information:

• The name of course.

• The number of course lecture credit hours. Has to be in the range of 1-3 (i.e. 1 ≤ credit hours ≤ 3). For the lab course option, ask the user to enter the following information:

• The name of course.

• The number of course lecture credit hours. Has to be in the range of 1-3 (i.e. 1 ≤ credit hours ≤ 3).

• The number of lab credit hours. As defined above since the number of course lecture hours have to be in the

  range of 1-3 (i.e. 1 ≤ lecture credit hours ≤ 3), the lab hours entered can also only be in the range of 1-3 (i.e. 1 ≤ lab hours ≤ 3) to satisfy the condition of total hours of 4. That is the total of the course lecture hours plus the lab hours has to be in the range of 2-4 (i.e. 2 ≤ total (lab + lecture credit hours) ≤ 4). For example, if the lecture credit hours entered is 3, lab hours can only be 1. If course lecture credit hours is 2, lab hours can be 1 or 2. If course lecture credit hours is 1, lab hours can be 1 or 2 or 3.

  OPTIONAL (5 POINTS): You will get bonus points if you write a function/s to read the information above (i.e. name of course, lecture credit hours, lab credit hours) entered by the user.

  Write a pair of overloaded functions called compute_tuition.

1. The first overloaded function should compute tuition for the course only option as follows,Tuition = lecture credit hours*rate.
   The function should return the tuition amount.

2. The second overloaded function should compute tuition for the lab course option as follows,

   Tuition = lecture credit hours *RATE + lab credit hours *FEE.

   The function should return the tuition amount.

Use global named constants for the rate per credit hour (RATE = 364.0) and lab fee per credit hour (FEE = 50.0)

Required Items:

1. Menufunction

2. Global named constants for RATE and FEE

3. Switch statement with case labels for course only and course with lab option

4. Range check on the credit hours entered

5. Two overloaded functions to compute_tuition

6. main()totestthefunctionsasshowninthesampleruns
