C is a procedural programming language known for its low-level access, efficiency, and portability. It’s based on functions and procedures, allowing direct interaction with hardware, making it suitable for systems programming. C also offers a simple syntax with core concepts like variables, data types, control structures, functions, pointers, arrays, strings, structures, and file I/O. 
 
Key Features of C:
  • Procedural Language:
    C is a procedural language, meaning it’s built around functions and procedures that execute in a specific order to solve a problem.
  • Low-Level Access:
    C provides low-level access to memory and hardware, making it ideal for tasks like operating system development and embedded systems.
  • Efficiency and Speed:
    C programs are known for their efficiency and speed, with minimal runtime overhead.
  • Portability:
    C code can be compiled and run on various platforms with minimal or no modification, thanks to its portability feature. 
     
Basic Syntax Example:
 
C
 
#include <stdio.h>int main() {    printf("Hello, World!\n");    return 0;}
Core Concepts in C:
  • Variables and Data Types:
    C supports various data types like int, float, char, etc., for storing different kinds of data.
  • Control Structures:
    C includes control structures like if, else, switch, for, while, and do-while loops for controlling the flow of execution.
  • Functions:
    C utilizes functions to modularize code, breaking down complex problems into smaller, manageable parts.
  • Pointers:
    Pointers in C allow direct memory manipulation, enabling efficient memory management and data access.
  • Arrays and Strings:
    C supports arrays for storing collections of similar data types and strings for storing sequences of characters.
  • Structures (struct):
    Structures allow grouping related data items of different types under a single name, creating custom data types.
