Hi,
My menu driven program that repeatedly calculates and prints the diameter of, circumference or area of circle, given the radius,
is not doing what I want it to do...
Can code doc / code friend point out how to make it work?
Thanks
Code:
#include<iostream>
using std::cout;
using std::cin;
using std::endl;
#include <iomanip>
using std::setprecision;
int main()
{
double Diameter, Area, Circumference, radius;
char D=0, A=0, C=0, X=0, input=0;
cout << "Please pick an option: " << endl
<< "Calculate the diameter of the circle: 'D' " << endl
<< "Calculate the area of the circle: 'A' " << endl
<< "Calculate the circumference: 'C' " << endl
<< "Exit the program: 'X' " << endl;
cin >> ( D || A || C || X )
cout << setprecision ( 2 )
{
if ( input == D ){
cout << "Enter the lenght of the radius: " << endl;
cin >> radius;
Diameter = 2* radius ;
cout << " The diameter of circle with radius " << radius << "is " << Diameter << endl;
}
if ( input == A )
{ cout << "Enter the lenght of the radius: " << endl;
cin >> radius;
Area = 3.14 * radius * radius ;
cout << " The area of cirlce with radius " << radius << "is" << Area << endl;
}
if ( input == C)
{ cout << "Enter the lenght of radius: " << endl;
cin >> radius;
Circumference = 2 * 3.14 * radius ;
cout << "The circumference of the circle with radius " << radius << "is " << Circumference << endl;
}
if ( input == X)
cout << "Good bye" << endl;
}
return 0;
}
