CP143: Structures and File Processing - Practice Exercises

Swift Tuition Practice Exercises

This repository contains 5 practice exercises for learning Structures and File Processing in C programming.

🚀 Quick Start

Option 1: Open in GitHub Codespaces (Recommended)

• Click the badge above to launch a fully configured development environment
• Compiler and all tools pre-installed
• Start coding immediately in your browser

Option 2: Clone Locally

git clone https://github.com/SwiftTuition/CP143-Structures-Exercises.git
cd CP143-Structures-Exercises

📦 Exercises Included

1. Exercise_01: Product Inventory System (Easy)

   • Structure basics and syntax
   • Arrays of structures
   • Searching and updating records

2. Exercise_02: Student Database (Medium)

   • Sequential file I/O with structures
   • Reading and writing text files
   • Statistical calculations

3. Exercise_03: Bank Account Manager (Medium)

   • Random-access file processing
   • Binary file I/O
   • Direct record access with fseek

4. Exercise_04: Contact Book System (Medium)

   • CRUD operations (Create, Read, Update, Delete)
   • Menu-driven interface
   • File persistence

5. Exercise_05: Library Management System (Hard)

   • Complete integrated system
   • Multiple data structures
   • Transaction processing

💡 How to Use

1. Read the README in each exercise folder
2. Open the .c file and locate the TODO comments
3. Implement the required functions
4. Compile and test:

   cd Exercises/Exercise_01
   gcc exercise_1.c -o exercise_1
   ./exercise_1

🛠️ Compilation

Using GCC:

gcc exercise_X.c -o exercise_X
./exercise_X

Using Codespaces:

• Terminal is already set up with GCC
• Just compile and run as shown above

📝 Tips for Success

• Start with Exercise 1 and progress sequentially
• Test frequently as you write code
• Don't forget to close files with fclose()
• Always check if fopen() returns NULL
• Use sizeof() for structure sizes in file I/O

✨ Good day, good people - Happy Coding!
