What are the key features of C programming?

C programming is known for its efficiency, portability, and low-level access to memory. Key features include:

1. Structured Language: C supports structured programming, which helps in organizing code.
2. Low-level Access: It allows manipulation of bits, bytes, and addresses, making it suitable for system programming.
3. Rich Library: C has a vast standard library that provides numerous built-in functions.
4. Portability: C programs can be compiled on different platforms with minimal changes.
5. Efficiency: C is highly efficient in terms of performance and resource management.

Can you explain what structured programming means?

Structured programming is a programming paradigm that emphasizes the use of control structures such as sequences, selections, and iterations to improve the clarity and quality of code. It encourages breaking down a program into smaller, manageable functions or modules, making it easier to understand, debug, and maintain.

What is the significance of pointers in C?

Pointers are a fundamental feature in C that allow you to directly access and manipulate memory. They enable dynamic memory allocation, efficient array handling, and the creation of complex data structures like linked lists and trees. Understanding pointers is crucial for effective C programming.

How does C handle memory management?

C provides manual memory management through functions like malloc(), calloc(), realloc(), and free(). This allows programmers to allocate and deallocate memory as needed, giving them control over resource usage, but it also requires careful management to avoid memory leaks and segmentation faults.
