Thread: Golden Ratio

hey,

I have to draw a spiral in my console window using the Fibonacci numbers.
I have to use a 2D array and plot in the values.

I have this algorithim which finds the values but I don't think this is enough. I need to find the values so I can draw the dots and make up the spiral.

Code:

#include <iostream>
#include <string>
using namespace std;

static const int n=20;

class ratio
    {
    public:
        ratio(int a):result(a==0?0:a==1?1:ratio(a-1)+ratio(a-2))
            { /* empty */ }
            
    public:operator int(){return result;}
    private:int result;
    
    };
    
    int main()
    {
        for(int a=0;a<n;a++)
        //cout <<"\n Golden Ratio("<<a<<")\t"<< ratio(a);
        cout << ratio(a) << "\n";
        return 0;
    }

thanks,mas

You will probably want to look into use of a graphics library to go with your protocol. Consoles are line by line displays. You could declare a large char array with space char to represent no data point and some other char to represent data point and print out line by line using ASCII text, but I doubt that's what you had in mind. There are a number of graphics libraries available. A search of the board may you give you some places to go, etc.
