Create Bank Management System in C Programming

Introduction

Creating a Bank Management System in C programming is a great way to learn about basic concepts like file handling, loops, and functions. This project is ideal for beginners who want to understand how a simple banking application works. In this guide, we will walk you through the step-by-step process of building a Bank Management System, including adding accounts, managing deposits and withdrawals, and viewing account details.

Step-by-Step Guide to Create Bank Management System in C Programming

Step 1: Set Up Your Environment

Before you start coding, make sure you have a C compiler installed on your computer. You can use GCC (GNU Compiler Collection) or any other C compiler like Turbo C.

Step 2: Define the Structure for Account Details

Start by defining a structure to store account details. This will include information like the account number, account holder's name, balance, and other necessary details.

#include <stdio.h>
#include <string.h>

struct Account {
    int accountNumber;
    char name[50];
    float balance;
};

Step 3: Create Functions for Basic Operations

Next, create functions to perform basic banking operations such as adding a new account, depositing money, withdrawing money, and checking the account balance.

Function to Add a New Account:

void addAccount(struct Account accounts[], int *numAccounts) {
    struct Account newAccount;
    printf("\nEnter account number: ");
    scanf("%d", &newAccount.accountNumber);
    printf("Enter account holder name: ");
    scanf("%s", newAccount.name);
    newAccount.balance = 0.0;
    accounts[*numAccounts] = newAccount;
    (*numAccounts)++;
    printf("\nAccount added successfully!\n");
}

Function to Deposit Money:

void deposit(struct Account accounts[], int numAccounts) {
    int accountNumber;
    float amount;
    printf("\nEnter account number: ");
    scanf("%d", &accountNumber);
    for (int i = 0; i < numAccounts; i++) {
        if (accounts[i].accountNumber == accountNumber) {
            printf("Enter amount to deposit: ");
            scanf("%f", &amount);
            accounts[i].balance += amount;
            printf("\nAmount deposited successfully!\n");
            return;
        }
    }
    printf("\nAccount not found!\n");
}

Function to Withdraw Money:

void withdraw(struct Account accounts[], int numAccounts) {
    int accountNumber;
    float amount;
    printf("\nEnter account number: ");
    scanf("%d", &accountNumber);
    for (int i = 0; i < numAccounts; i++) {
        if (accounts[i].accountNumber == accountNumber) {
            printf("Enter amount to withdraw: ");
            scanf("%f", &amount);
            if (accounts[i].balance >= amount) {
                accounts[i].balance -= amount;
                printf("\nAmount withdrawn successfully!\n");
            } else {
                printf("\nInsufficient balance!\n");
            }
            return;
        }
    }
    printf("\nAccount not found!\n");
}

Function to Check Account Balance:

void checkBalance(struct Account accounts[], int numAccounts) {
    int accountNumber;
    printf("\nEnter account number: ");
    scanf("%d", &accountNumber);
    for (int i = 0; i < numAccounts; i++) {
        if (accounts[i].accountNumber == accountNumber) {
            printf("\nAccount Holder: %s\n", accounts[i].name);
            printf("Balance: %.2f\n", accounts[i].balance);
            return;
        }
    }
    printf("\nAccount not found!\n");
}

Step 4: Create the Main Menu

To make the program user-friendly, create a main menu that allows users to choose different banking operations.

int main() {
    struct Account accounts[100];
    int numAccounts = 0;
    int choice;
    do {
        printf("\n==============================\n");
        printf("  WELCOME TO BANK MANAGEMENT SYSTEM  \n");
        printf("==============================\n");

        printf("\nPlease choose an option:\n");
        printf("[1] Add Account\n");
        printf("[2] Deposit Money\n");
        printf("[3] Withdraw Money\n");
        printf("[4] Check Balance\n");
        printf("[5] Exit\n");

        printf("\nEnter your choice: ");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                addAccount(accounts, &numAccounts);
                break;
            case 2:
                deposit(accounts, numAccounts);
                break;
            case 3:
                withdraw(accounts, numAccounts);
                break;
            case 4:
                checkBalance(accounts, numAccounts);
                break;
            case 5:
                printf("\nThank you for using the Bank Management System. Goodbye!\n");
                break;
            default:
                printf("\nInvalid choice! Please try again.\n");
        }
    } while (choice != 5);

    return 0;
}

Compiling and Running the Program

Step 1: Write the Code

Write the code in a text editor and save it with a .c extension, for example, bank_management_system.c.

Step 2: Compile the Program

Open the terminal or command prompt and navigate to the directory where your C file is saved. Use the following command to compile the program:

gcc bank_management_system.c -o bank_management_system

This command will compile the code and create an executable file named bank_management_system.

Step 3: Run the Program

To run the program, After compiling, In the same Command Prompt window, type:

bank_management_system

The program will start, and you can interact with the main menu to perform various banking operations.

Creating a Bank Management System in C Programming is a valuable exercise for beginners. It helps you understand core concepts like structures, file handling, and basic algorithms. This project is not only a good learning experience but also a stepping stone towards more complex programming challenges.
