Customer Billing System || C Code Projects for School students

Reference: CCP_L01_A02_Customer Billing System

Introduction

In this blog post, we will explore a simple Customer Billing System designed using the C programming language. This project is perfect for students (8-16 years old) learning C, as it covers essential programming concepts like file handling, structures, functions, and modular design.

Why Build a Customer Billing System?

A billing system is essential for cafes, small stores, and restaurants to generate accurate bills, manage customers, and store invoices. This project teaches real-world coding skills in C while being beginner-friendly.

Project Features

✔ Customer Management: Add and store customer details (ID, name, contact, address).
 ✔ Product Management: Add and update product prices.
 ✔ Billing System: Generate bills, calculate totals, and apply taxes/discounts.
 ✔ File Storage: Store data permanently using .dat files.
 ✔ User-Friendly Menu: Simple menu-driven interface.
 ✔ Error Handling: Validates input and handles file-related errors.

System Architecture

This project follows a modular design, consisting of:

●     User Interface Layer (Handles input & output)

●     Business Logic Layer (Processes data)

●     File Handling Layer (Stores customer, product, and billing information in .dat files)

How It Works

1️⃣ Add Customers & Products – Store customer and product details.
 2️⃣ Generate Bill – Select a customer, choose products, enter quantity, and get the total bill.
 3️⃣ View Records – Display all customers, products, and bills.
 4️⃣ Exit Program – Safely close the system.

C Code Implementation

The full C code for this project is written in a single source file for simplicity. It includes:

●     Structures (struct) for Customer, Product, and Bill data.

●     File handling (fopen, fwrite, fread) for persistent storage.

●     Modular functions for customer, product, and billing operations.

How to Run This Project in Code::Blocks IDE

1️⃣ Open Code::Blocks and create a new C Console Application project.
 2️⃣ Copy and paste the provided C code into main.c.
 3️⃣ Compile and run the program (F9).
 4️⃣ Use the menu options to add customers, products, generate bills, and view records.

Sample Data Files (customers.dat, products.dat, bills.dat)

●     Customers and products are stored in binary files.

●     If files do not exist, the program creates them automatically.

●     You can view the stored data using the built-in display functions.

Enhancements & Future Features

🔹 Admin Authentication – Add password-protected admin access.
 🔹 Search Functionality – Search for customers, products, or past invoices.
 🔹 Export Bills as TXT/PDF – Save invoices for printing.
 🔹 Multi-User Role – Different access levels for Admin, Operator, and Customer.
 🔹 GUI Version – Convert the console-based system into a graphical application.

Final Thoughts

The Customer Billing System in C is an excellent beginner-friendly project that helps students understand basic programming concepts while working on a real-world application.

🚀 Try building this system, enhance it with new features, and share your learning experience!

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
