What are the important concepts in C?

Important Concepts in C Programming Concept Description 1. Variables & Data Types Store data of various types (int, char, float, double). 2. Operators Arithmetic, logical, relational, bitwise, assignment. 3. Control Structures Decision making (if, else, switch), loops (for, while, do-while). 4. Functions Reusable blocks of code that perform specific tasks; support parameter passing and return values. 5. Arrays Collection of elements of the same type stored in contiguous memory. 6. Pointers Variables that store memory addresses; powerful for dynamic memory and array manipulation. 7. Strings Arrays of characters ending with a null terminator (\0). 8. Structures (struct) Custom data types to group related variables under one name. 9. Dynamic Memory Allocation Using malloc(), calloc(), realloc(), and free() to allocate memory at runtime. 10. File Handling Reading from and writing to files using fopen(), fread(), fprintf(), etc. read less
