This is a collection of C programs that I have done in my school. These programs are mostly based on the topics covered in the syllabus of the WBCHSE board for class 11 and 12. Some of the topics include:

• Arrays
• Pointers
• Structures
• Functions
• Recursion
• File handling
• Linked lists
• Stacks and queues

To run these programs, you will need a C compiler and an IDE. You can use any compiler and IDE of your choice, but I recommend using [GCC] as the compiler and [Code::Blocks] as the IDE. You can download them from their respective websites.

To compile and run a program, follow these steps:

Open the program file in Code::Blocks. Click on Build and Run from the menu bar or press F9. A console window will open and display the output of the program. Disclaimer These programs are for educational purposes only. They may not be the most efficient or optimal solutions to the problems. They may also contain errors or bugs. Use them at your own risk.

I would like to thank my teachers and classmates for their guidance and support in learning C programming. I would also like to thank the authors of the following books and websites for providing useful references and examples:

• [Let Us C] by Yashavant Kanetkar
• [Programming in ANSI C] by E. Balagurusamy
• [GeeksforGeeks]
