1. Understand the Basics: Start with basic concepts like variables, data types, operators, and control statements (if-else, loops).

2. Learn Syntax: Focus on how C code is written – including functions, arrays, pointers, and structures.

3. Practice Regularly: Write simple programs daily. Practicing is key to mastering C.

4. Use Online Platforms: Websites like GeeksforGeeks, W3Schools, and Tutorialspoint have beginner-friendly tutorials.

5. Work on Small Projects: Try building calculators, pattern printers, or simple file handling programs.

If Hindi is more comfortable for you, then check out bccfalna.com – they have a C language book in Hindi, which is very helpful for beginners who prefer learning in their native language.

Important Note (Exam Point of View)

In most C language exams, the following topics are almost guaranteed to appear:

Dynamic Memory Allocation

File Handling

Structures and Unions

Pointers

Recursive Functions

These are considered very important, both for theory and coding-based questions. Make sure to prepare them thoroughly.
