Key Concepts Demonstrated

This project showcases the use of the following C programming concepts:

• File I/O: Reading from and writing to files.
• Pointers: Efficient memory management and data manipulation.
• Strings: Handling and manipulating text data.
• Functions: Modularizing the code into reusable blocks.
• Dynamic Memory Allocation: Allocating and reallocating memory dynamically to handle varying data sizes and ensure efficient memory usage.

Project Description

In this project:

1. A bill template is referenced from a file (BillTemplate.txt), which serves as the base structure for the receipt.
2. The user is prompted to input their name.
3. Additional predefined strings, such as the company name, bill amount, and outlet name, are incorporated into the receipt.
4. A new string is generated by combining the user input and predefined data.
5. The updated data is saved in a new file, creating a complete and personalized bill receipt.

How to Run

1. Clone the repository or download the source code.
2. Ensure the file BillTemplate.txt exists in the same directory as the program.
3. Compile the C program using any standard C compiler (e.g., GCC).

   gcc Auto_Bill_Generator.c -o Auto_Bill_Generator

4. Run the executable:

   ./Auto_Bill_Generator

5. Follow the on-screen instructions to input your name and generate the bill receipt.
