Student Result System || C Code Projects for School students

 Reference: CCP_L01_A11_Student Result System

Introduction

The Student Result System in C is a simple yet effective project for beginners and school students (ages 8-16) to understand the core concepts of C programming. This system allows users to add, view, update, delete, and list student results using file handling for data storage.

In this blog post, we will explore the features, functionality, source code, and implementation of this project. Let’s dive in! 🚀

---

📌 Features of Student Result System

✅ Add Student Records (Roll Number, Name, Marks, Percentage)
 ✅ View Student Result by Roll Number
 ✅ Update Student Marks and Recalculate Percentage
 ✅ Delete Student Record from File
 ✅ List All Students with Their Scores
 ✅ Persistent Storage Using File Handling

This project follows modular programming and ensures error handling & data validation for basic security.

📂 Project Structure

●     Single Source File (student_result_system.c)

●     Data Stored in a Text File (students.txt)

●     Functions Used: fopen(), fclose(), fprintf(), fscanf()

●     Concepts Used: Structures, File Handling, Loops, Functions, Conditional Statements

---

💻 How to Use the Code in Code::Blocks

1. Open Code::Blocks IDE and create a new C file.
2. Copy & paste the provided C code into the file.
3. Save the file as student_result_system.c.
4. Click on Build & Run (F9 in Code::Blocks).
5. Use menu options to interact with the system.
6. The data is stored in students.txt automatically.

🛠️ Sample Code Snippet (Adding Student Record)

void addStudent() {

    FILE *fp = fopen("students.txt", "a");

    Student s;

    printf("Enter Roll No: ");

    scanf("%d", &s.rollNo);

    printf("Enter Name: ");

    scanf(" %[^"]", s.name);

    printf("Enter marks for 5 subjects: ");

    s.total = 0;

    for (int i = 0; i < 5; i++) {

        scanf("%f", &s.marks[i]);

        s.total += s.marks[i];

    }

    s.percentage = s.total / 5;

    fprintf(fp, "%d %s %.2f %.2f %.2f %.2f %.2f %.2f %.2f\n", s.rollNo, s.name, s.marks[0], s.marks[1], s.marks[2], s.marks[3], s.marks[4], s.total, s.percentage);

    fclose(fp);

    printf("Student Record Added Successfully!\n");

}

📊 How the System Works

1. User selects an option from the menu.
2. If Adding a Student:

○     User enters Roll No, Name, and Marks.

○     Data is stored in students.txt.

3. If Viewing a Student:

○     User enters Roll No.

○     System fetches & displays results from the file.

4. If Updating a Student:

○     The system reads the file and updates the record.

5. If Deleting a Student:

○     The record is removed from the file.

6. If Listing Students:

○     Displays all student records stored in the file.

🔥 Why This Project is Useful for Students

●     Helps in learning file handling in C.

●     Introduces structuring real-world data (student records).

●     Enhances logic-building skills using conditional statements and loops.

●     Easy to expand with additional features like sorting & searching.
