C Programming Features

C is a powerful and versatile programming language known for its rich set of features that enable efficient and flexible coding. Below are the key features that make C a preferred choice for system programming, embedded systems, and more.

🌟 Key Features of C

• Procedural Programming: C follows a structured, top-down approach, organizing code into functions for modularity and reusability.
• Low-Level Access: Provides direct memory manipulation through pointers, ideal for system-level programming.
• Portability: C programs can be compiled and executed on various platforms with minimal modifications.
• Rich Standard Library: Includes built-in functions for input/output, string handling, memory management, and mathematical operations.
• Fast and Efficient: As a compiled language, C generates machine code, ensuring high performance.
• Flexibility: Supports both high-level and low-level programming, making it suitable for diverse applications.
• Modularity: Allows code to be split into multiple files, enhancing maintainability and collaboration.

🧠 Additional Characteristics

• Static Typing: Variables must be declared with a specific data type (e.g., int, float) before use.
• Extensibility: C can be extended with user-defined libraries and functions.
• Control Structures: Offers robust constructs like if, for, while, and switch for logic and flow control.
• Dynamic Memory Allocation: Functions like malloc() and free() enable runtime memory management.

📝 Example: Using Pointers in C

Here’s a simple C program demonstrating the use of pointers, a key feature of C:

#include 

int main() {
    int num = 10;
    int *ptr = # // Pointer to num
    printf("Value of num: %d\n", num);
    printf("Address of num: %p\n", ptr);
    printf("Value via pointer: %d\n", *ptr);
    return 0;
}
