Assignment 2 as per c++ programming

An inline function for the programmed by. Three regular functions, one for getting the data on the four students, one for calculating the GPA, and one for the output. One of the functions must be recursive.

This project requires the use of various control structures for calculating the grade point averages (GPA) for four students. Your program should ask for the grades for each student. Each student will have five grades. After all the students grades have been entered, the program will then display each student name and their calculated GPA.

Project Requirements:

1. Find a function to use recursion in and use it.

2. Do not include any unused header files.

3. Grades can be entered in upper or lower case.

4. The input will be A, B, C, D, & F. Standard letter grades.

5. GPAs are 4.0, 3.0, 2.0, 1.0 & 0.0 respectively

6. Format output to 3 decimal points (i.e. 3.500, 2.750).

7. There will be only four students (Freddie, Jane, Jonathan, & Mary)

8. Each student will have 5 grades to enter.

9. The final output for the GPAs will be in columnar output.

10. Only catch common incorrect letter grades (i.e. K, Z, O, etc).
