File Structures Project (C++)

A console-based fast-food ordering system in C++ that demonstrates flat-file storage techniques — built for a File Structures course.

What it is

A college File Structures course project exploring how data can be persisted and retrieved from plain text files without a database. The main program ("Peter's Jr. Fast Food") is a command-line ordering system where everything — customer accounts and order history — lives in pipe-delimited text files that are searched sequentially and appended to using fstream.

Features

• Sign-up and login — customer records (username|password|phone|address|) are appended to Customers.txt; login validates credentials with a sequential scan and strtok field parsing
• Menu ordering — pizzas, burgers, sandwiches, rolls, and biryani, with flavour, size, and quantity selection
• Bill generation — computes the total and prints an order summary
• Order persistence — each order (quantity|total|item|) is appended to Orders.txt
• Previous-order lookup — retrieves a returning customer's past orders by scanning the orders file

File-structure concepts used

• Delimited variable-length records in sequential text files
• Append-only writes (ios::app) and sequential search for retrieval
• Field tokenization with strtok on a | delimiter

Build and run

The code uses Windows-specific headers (conio.h, process.h) and itoa, so it targets Windows compilers (e.g. MinGW/Dev-C++):

# Rename the source and compile with MinGW
copy "Check1.cpp.txt" Check1.cpp
g++ Check1.cpp -o Check1.exe
Check1.exe

Run it from the Final FS project directory so the program can find Customers.txt and Orders.txt. A pre-built Check1.exe is also included.
