Thread: problem with simple program

Code:

 
//this program will calculate the area of a circle.
#include <iostream>
#include <iomanip>
#include <cstdlib>
using std::cout;
using std::cin;


int main()
    {
          double pi = "3.14";
          double radius = "0.0";
          double area = "0.0";
          
          cout <<"Please enter the radius of a circle: ";
          cin >> radius;
          
          area = pi * radius * radius ; //calculates a circle's area
          
          cout <<"\n\nThe area is: " << area;
          
          cout <<"\n\n";
          system("PAUSE");
          return 0;
    }

The problem is this:

Code:

11 C:\Dev-Cpp\areaOfCircle.cpp cannot convert `const char*' to `double' in initialization

For the life of me I can't figure out what's wrong.

Get rid of the quotes around your numbers
