Programming Example
C Program to Calculate Area of Circle
In this c program we will calculate Area of Circle
#include"stdio.h"
int main() {
float radius, area;
printf("\nEnter the radius of Circle : \n");
scanf("%f", &radius);
area = 3.14 * radius * radius;
printf("\nArea of Circle : %f \n", area);
return (0);
}
Enter the radius of Circle :
6
Area of Circle : 113.040001

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
