Mastering Circle Math: Calculating Circumference and Area in C

Calculating Circumference and Area of a Circle in C

In this blog post, we'll explore a simple C program that calculates the circumference and area of a circle based on the provided radius. Let's take a look at the C code:

#include <stdio.h>

int main() {
    const double PI = 3.14159;
    double radius;
    double circumference;
    double area;

    printf("\nEnter radius of a circle :");
    scanf("%lf", &radius);

    circumference = 2 * PI * radius;
    area = PI * radius * radius;

    printf("Circumference: %lf\n", circumference);
    printf("Area: %lf\n", area);

    return 0;
}
        

Copy and paste this C code into your favorite compiler, and you'll be able to calculate the circumference and area of a circle by providing the radius.

Feel free to modify and experiment with the code to enhance your understanding of C programming. Happy coding!
