    C is a powerful general-purpose programming language used for system software, application software, and more. Below is a simple example of a C program that prints "Hello, World!" to the console.

    #include <stdio.h>

    int main() {
    printf("Hello, World!");
    return 0;
    }

    Key Concepts in C

    Variables and Data Types

    Variables are used to store data, and data types specify the type of data a variable can hold. Common data types include int, float, char, and double.

    Control Structures

    Control structures like if, else, for, and while are used to control the flow of the program.

    Example:

    #include <stdio.h>

    int main() {
    int num = 10;

    if (num > 0) {
    printf("Positive number");
    } else {
    printf("Negative number");
    }

    return 0;
    }
    Copied!

    Functions

    Functions are blocks of code that perform specific tasks. They help in organizing code and reusability.

    Example:

    #include <stdio.h>

    void greet() {
    printf("Hello, World!");
    }

    int main() {
    greet();
    return 0;
    }
    Copied!
