Fee Management Application in C++
You are attending an online course in C++. The course costs $500 as the standard fee. Early bird payment gets a 10% discount on the standard fee. Students also have to pay for course materials which cost$20workbook. There are in total 2workbooksfor the course. Including you, there are a total of 5 students who have enrolled in the course. Write a simple C++ program to show the following:
- The total cost paid by each student. You need to clearly show if the student is benefiting from the early bird discount or not.
- The total cost paid by all the student.
