CGPA Calculator

Overview

The CGPA Calculator is a command-line application designed to calculate the Cumulative Grade Point Average (CGPA) and Grade Point Average (GPA) based on user inputs. This tool supports calculation for both semester-based CGPA and course-based GPA, making it versatile for different academic requirements.

Features

CGPA Calculation (-c option)

• Input: Number of semesters, GPA for each semester, and credits for each semester.
• Output: Calculates and displays the Cumulative Grade Point Average (CGPA).

GPA Calculation (-g option)

• Input: Number of courses, grade for each course, and credits for each course.
• Output: Calculates and displays the Grade Point Average (GPA).

Usage

To use the CGPA Calculator, compile the source code and run the executable with the desired option.

Compile the Code

To compile the code, use a C++ compiler. For example, using g++:

g++ -o cgpa_calculator main.cpp cgpa_functions.cpp

Run the Program

Calculate CGPA

./cgpa_calculator -c

Follow the prompts to enter the number of semesters, GPA, and credits.

Calculate GPA

./cgpa_calculator -g

Follow the prompts to enter the number of courses, grades, and credits.

Examples

Example 1: Calculating CGPA

./cgpa_calculator -c
Enter number of Semesters: 2

Enter the GPA for semester 1: 8.5
Enter the Credits for semester 1: 20

Enter the GPA for semester 2: 9.0
Enter the Credits for semester 2: 25

CGPA = 8.80

Example 2: Calculating GPA

./cgpa_calculator -g
Enter number of courses: 3

Enter the Grade for course 1: 9.0
Enter the Credits for course 1: 4

Enter the Grade for course 2: 8.5
Enter the Credits for course 2: 3

Enter the Grade for course 3: 7.0
Enter the Credits for course 3: 2

GPA = 8.60

TODO

Planned or Future Updates

• Enhanced Input Validation:

  • Implement comprehensive checks to ensure all input values are within valid ranges and handle unexpected inputs gracefully.

• Support for Different GPA Scales:

  • Add options to handle various grading scales and systems (e.g., 4.0 scale, 5.0 scale).

• User-Friendly Interface:

  • Develop a graphical user interface (GUI) version of the calculator for improved usability.

• File Input/Output:

  • Allow users to input data from files and output results to files for batch processing.

• Error Handling Improvements:

  • Enhance error messages and logging for better debugging and user feedback.

• Advanced Calculations:

  • Include features for weighted GPA calculations and GPA projections based on current performance.
