Bank Management System || C Code Projects for School students

Reference: CCP_L01_A01_Bank Management System

🏦 Introduction

Managing bank transactions is a crucial real-world application. In this project, we will develop a simple Bank Management System in C, focusing on file handling for data storage. This project is designed for beginners and school students (8-16 years old) to understand structured programming, functions, and data persistence.

---

📌 Features of the System

✔ Create Account – Store customer details (Account Number, Name, Balance).
✔ Deposit Money – Add funds to an account.
✔ Withdraw Money – Deduct funds securely.
✔ Check Balance – Retrieve account information.
✔ File-Based Storage – Data remains even after program exit.

This system follows a menu-driven approach, allowing users to navigate banking operations easily.

💡 Project Implementation

👉 Technologies Used:

●     Programming Language: C

●     Compiler: MinGW (Code::Blocks IDE)

●     Storage: File Handling (bank_accounts.dat)

📝 C Program Code – Bank Management System

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
 
#define FILENAME "bank_accounts.dat"
 
struct Account {
    int acc_no;
    char name[50];
    float balance;
};
 
void createAccount();
void deposit();
void withdraw();
void checkBalance();
void displayMenu();
 
int main() {
    int choice;
    do {
        displayMenu();
        printf("\nEnter your choice: ");
        scanf("%d", &choice);
        switch (choice) {
            case 1: createAccount(); break;
            case 2: deposit(); break;
            case 3: withdraw(); break;
            case 4: checkBalance(); break;
            case 5: printf("Exiting...\n"); break;
            default: printf("Invalid choice! Try again.\n");
        }
    } while (choice != 5);
    return 0;
}
 
void displayMenu() {
    printf("\n===== Bank Management System =====\n");
    printf("1. Create Account\n");
    printf("2. Deposit Money\n");
    printf("3. Withdraw Money\n");
    printf("4. Check Balance\n");
    printf("5. Exit\n");
}
 
void createAccount() {
    struct Account acc;
    FILE *fp = fopen(FILENAME, "ab");
    if (!fp) {
        printf("File Error!\n");
        return;
    }
    printf("Enter Account Number: ");
    scanf("%d", &acc.acc_no);
    printf("Enter Name: ");
    scanf("%s", acc.name);
    acc.balance = 0.0;
    fwrite(&acc, sizeof(struct Account), 1, fp);
    fclose(fp);
    printf("Account Created Successfully!\n");
}

📂 How Data is Stored?

The system saves account details in a binary file (bank_accounts.dat), so data remains even after program execution stops.

🗃 File Example (Binary Representation):

1001 John 500.00

1002 Alice 1200.50
