GPA Calculator || C Code Projects for School students

 Reference: CCP_L01_C06_GPA Calculator

Introduction

Are you a beginner in C programming looking for a practical project? A GPA Calculator is a perfect academic project to help students track their performance while learning C programming basics. In this blog, we’ll build a simple yet effective GPA Calculator in C using arrays, file handling, and modular functions. This project is ideal for school students (ages 8-16) and follows beginner-friendly coding standards.


1️⃣ Project Overview

The GPA Calculator in C allows users to:
 ✅ Input course names, letter grades (A, B, C, etc.), and credit hours.
 ✅ Convert letter grades into numerical grade points.
 ✅ Calculate GPA using the standard formula.
 ✅ Save GPA records into a file (
gpa_records.txt).
 ✅ View past GPA records at any time.


2️⃣ Features & Functionalities

🟢 Simple Menu System – Allows users to enter grades, calculate GPA, and view past records.
 ðŸŸ¢ Grade Conversion System – Converts letter grades (A, B+, C, etc.) into grade points.
 ðŸŸ¢ GPA Calculation Formula – Uses a weighted GPA formula:

GPA=∑(grade_points×credit_hours)∑credit_hoursGPA = \frac{\sum (grade\_points \times credit\_hours)}{\sum credit\_hours}

🟢 File Handling – Saves GPA history in gpa_records.txt.
 ðŸŸ¢ User-Friendly & Error Handling – Ensures valid inputs for grades and credit hours.


3️⃣ C Code Implementation

The program consists of four core functions:
 ðŸ“Œ
enterGrades() – Takes course names, grades, and credit hours.
 ðŸ“Œ
convertGradeToPoints() – Converts letter grades into numerical points.
 ðŸ“Œ
calculateGPA() – Computes the weighted GPA.
 ðŸ“Œ
saveToFile() & viewRecords() – Handles GPA storage and retrieval.
