- Function Pointers: Basics of pointers to functions.
3.3. Structures and Unions
- Structures: Defining and using structures.
- Unions: Understanding and using unions.
3.4. File I/O
- File Handling: fopen, fclose, fread, fwrite, fprintf, fscanf, etc.
- File Operations: Reading from and writing to files.
4. Debugging and Testing
4.1. Debugging Tools
- Using a Debugger: Basics of gdb or IDE-specific debuggers.
- Debugging Techniques: Setting breakpoints, inspecting variables, and stepping through code.
4.2. Writing Test Cases
- Unit Testing: Basics of writing unit tests for C programs.
- Test Frameworks: Introduction to frameworks like CUnit or Check.
5. Projects and Practice
5.1. Building Small Projects
- Console Applications: Create simple programs like a calculator, tic-tac-toe, or a text-based adventure game.
- File Manipulation Programs: Write programs that perform operations on files, such as sorting or searching data in a file.
5.2. Coding Challenges
- Online Platforms: Engage in coding challenges on platforms like HackerRank, LeetCode, or CodeChef.
- Practice Problems: Regularly solve problems to reinforce concepts and improve problem-solving skills.
6. Resources and Community
