input Radius and compute and display the Area. Your program will be terminated if input zero

in the radius.

Answer 1

#include<iostream>
using namespace std;
int main(){
	 double pi=3.1415, r;
	 do{
	 	cout<<"Enter radius:\n";
	 	cin>>r;
	    double area = pi *(r*r);
	    cout<<"The radius is: "<<r<<"\nThe area is: "<<area<<endl;
	 } while(r !=0);
	 cout<"The program terminated successfully";
}
