Explanation:
1. The program starts by including the necessary header file iostream, which allows us to work with
input and output streams in C++.
2. The first overloaded function calcFees is declared with two parameters: int numModules and float
moduleFee. This function calculates the tuition fees when there are no repeated modules. It
multiplies the number of modules by the fee for each module and returns the total fees.
3. The second overloaded function calcFees is declared with four parameters: int numModules, float
moduleFee, int numRepeatedModules, and float repeatedModuleFee. This function calculates the
tuition fees when there are repeated modules. It calculates the fees for the modules taken for the
first time using the same logic as the previous function, and then adds the fees for the repeated
modules. The total fees are returned.
4. The main function is defined, which is the entry point of the program.
5. Inside the main function, the necessary variables are declared to store the user input:
numModules, numRepeatedModules, moduleFee, and repeatedModuleFee.
6. The user is prompted to enter whether the student repeats any modules, and the value is stored in
the repeatModules variable.
7. Next, the user is asked to input the number of modules enrolled for the first time (numModules)
and the fee for those modules (moduleFee).
8. Based on the value of repeatModules, the appropriate overloaded function is called to calculate
the tuition fees. If the student doesn't repeat any modules, the first calcFees function is used;
otherwise, the second calcFees function is used.
9. If the user entered that the student repeats modules, the program prompts for the number of
repeated modules (numRepeatedModules) and the fee for those modules (repeatedModuleFee).
10. The total fees are calculated by assigning the result of the calcFees function call to the totalFees
variable.
11. Finally, the total tuition fees are displayed to the user using std::cout.
The two overloaded functions are calcFees. One version accepts the number of modules and fee for the
modules enrolled for the first time, while the other version accepts additional parameters for the number
of repeated modules and fee for those repeated modules.
