Question

At KWT College of Education, students pay R3500 for a module and they are allowed to register for a 

minimum of two and a maximum five modules per semester. In order for students to register they must 

pay at least a minimum registration fee of R2000. The remaining amount must then be paid in four equal 

payments at the end of March, April, May and at the end of June. 

Write a C++ program that will help determine the amount payable by doing the following:

 Declare all constants and necessary variables.

 Prompt the user for the student number or XXX to exit (see Figure 3.1).

 Determine if the number of subjects entered is valid by making use of a pre-test loop.

o If a valid student number is entered, do the following: 

 Prompt the user for the number of modules and the registration fee as shown in 

Figure 3.2.

 Validate the number of modules and the registration fee using the
