Flow chart
💻 Program Code
#include"stdio.h"
void main()
{
int r;
float pi = 3.14, area, circumference;
printf("enter radius of circle: \n");
scanf("%d",&r);
area = pi * r * r;
printf("area of circle=%f \n",area);
circumference = 2 * pi * r;
printf("circumference=%f \n", circumference);
}
🖥 Program Output
enter radius of circle:
6
area of circle=113.040001
circumference=37.680000

🎯 How to learn from this example
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
🔥 Practice suggestion
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
