Introduction
Are you a beginner in C programming?
Looking for a simple yet practical project to improve your coding skills? In
this post, we’ll guide you through building a Student Grade Book System in C, a perfect project for school
students (8-16 years old) and beginners. This project involves file handling, data structures, and modular
programming, helping you understand how to store, retrieve, and process
student grades efficiently.
🔹 Features of Student
Grade Book in C
✔
Add Student Records – Store student name, roll number,
and marks.
✔ Display Student Records – View all student data.
✔ Search by Roll Number – Quickly find a student’s grades.
✔ Calculate Statistics – Get the highest, lowest, and average marks.
✔ File-based Storage – Data is
saved in a file (grades.dat) for later use.
🔹 System Requirements
📌 Programming Language: C
📌 Compiler: MinGW (Code::Blocks IDE)
📌 Operating System: Windows 10 (or later)
📌 Concepts Used: Functions, Structures, File Handling, Loops,
Conditional Statements
🔹 How the Code Works
The Student
Grade Book project is built using C
structures to store student details and file handling techniques to manage records. The project uses a menu-driven approach, allowing users to
choose different actions like adding students, searching, or calculating
statistics.
When you run the program, you will see
the following menu:
Student Grade Book System
1. Add Student Record
2. Display Student Records
3. Search Student by Roll Number
4. Calculate Statistics
5. Exit
Enter your choice:
Based on your selection, the program
performs the corresponding action.
🔹 Sample Code for the
Student Grade Book System
Here’s a simplified version of the C program:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
typedef struct {
int
rollNo;
char
name[50];
float marks;
} Student;
#define FILE_NAME "grades.dat"
void addStudent();
void displayStudents();
void searchStudent();
void calculateStatistics();
int main() {
int
choice;
while (1) {
printf("\\nStudent Grade Book System\\n");
printf("1. Add Student Record\\n2. Display Student Records\\n3.
Search Student\\n4. Calculate Statistics\\n5. Exit\\n");
printf("Enter your choice: ");
scanf("%d", &choice);
switch (choice) {
case 1: addStudent(); break;
case 2: displayStudents(); break;
case 3: searchStudent(); break;
case 4: calculateStatistics(); break;
case 5: exit(0);
default: printf("Invalid choice! Try again.\\n");
}
}
return 0;
}
void addStudent() {
FILE
*file = fopen(FILE_NAME, "ab");
if
(!file) { printf("Error opening file!\\n"); return; }
Student s;
printf("Enter Roll Number: "); scanf("%d",
&s.rollNo);
printf("Enter Name: "); scanf(" %[^\"]s",
s.name);
printf("Enter Marks: "); scanf("%f", &s.marks);
fwrite(&s, sizeof(Student), 1, file);
fclose(file);
printf("Student record added successfully!\\n");
}
🔹 How to Run the Code
in Code::Blocks IDE
- Open Code::Blocks and create a new C project.
- Copy-paste
the provided code into the file
(gradebook.c).
- Press Ctrl + F9 to compile and Ctrl + F10
to run.
- Interact with the program using the menu-driven options.
🔹 Enhancements &
Future Improvements
🚀 Additional Features to Implement:
✅ Sorting Student Records (by name, marks)
✅ Exporting Reports to CSV or TXT files
✅ Graphical Grade Representation (ASCII-based bar charts)
✅ Database Support (SQLite) for
better scalability
🔹 Conclusion
The Student
Grade Book System in C is an excellent
project for beginners, covering essential C programming concepts like file handling, structures, and user input
handling. By implementing this project, you’ll gain real-world coding experience while improving your problem-solving
skills.
