Thank you for your help...

I am just not very familiar with "while". I am getting an error when inserting while statement....

This is what I have so far:

Code:

#include<stdio.h>
#include<math.h>
#define PI 3.1416
int main(void)
{
float radius, diamater, circumference;
printf("Please enter the radius of your circle: ");
scanf("%f",&radius);
diamater = radius*2;
circumference =PI*diamater;
area=(PI*radius*radius);
printf("The diameter is: %0.2f\n",diamater);
printf("the circumference is: %0.2f\n",circumference);
printf("the area is: %0.2f\n",area);
return 0;
}

My question is how where can I place while statement?

Thank you for your help
