A simple console-based GPA and CGPA calculator written in C++. The program takes course names, grades, and credits obtained in each course during each semester as input to calculate GPA and CGPA.

1. Run the program in your preferred IDE.
2. Enter the number of completed semesters.
3. For each semester:
   • Enter the number of courses.
   • For each course:
     • Enter the course name.
     • Enter the achieved grade(e.g., A+, A, A-, ..., F).
     • Enter the credit hours of the course.

The program will then display the GPA and credit hours for the current semester, as well as the CGPA and total credit hours up to that point.

After performing the calculation, users are presented with the following options:

• 0 to Exit the program.
• 1 to Calculate CGPA again.

• This program will clear the console before each new set of calculations using (system("cls")). Might not work on all platforms.
• This program assumes that the user enters all valid inputs for grades and credit hours.
• This program uses a default grade point scale. To customize it, modify the HashMap in the code. Be aware that any changes may affect the GPA and CGPA accuracy.
