Mini Projects

Mini projects help students connect C concepts with real applications. They improve logic, file handling, functions and data structure skills.

Project Ideas

• Student Record Management System
• Library Book Management
• Bank Account Management
• Quiz Application
• Billing System
• Contact Book
• Bus Reservation System
• Tic Tac Toe Game
• Number Guessing Game
• Employee Payroll System

Student Record Project

#include <stdio.h>

typedef struct {
    int roll;
    char name[30];
    float marks;
} Student;

void addStudent() {
    Student s;
    FILE *fp = fopen("students.dat", "ab");
    printf("Enter roll, name, marks: ");
    scanf("%d %s %f", &s.roll, s.name, &s.marks);
    fwrite(&s, sizeof(Student), 1, fp);
    fclose(fp);
}

void displayStudents() {
    Student s;
    FILE *fp = fopen("students.dat", "rb");
    while(fread(&s, sizeof(Student), 1, fp) == 1) {
        printf("%d %s %.2f\n", s.roll, s.name, s.marks);
    }
    fclose(fp);
}

int main() {
    addStudent();
    displayStudents();
    return 0;
}

Build Steps

• Decide project title and features
• Create menu options
• Use functions for each feature
• Use structure for records
• Use file handling for permanent storage
• Test add, view, search, update and delete operations

Summary

• Mini projects build confidence
• Use functions to organize code
• Use structures for records
• Use files for data storage
• Start small and add features step by step
