I am writing a recursive program to draw the lines recursively, given the
range[min,max] and number of intervals (n) between the range.
The problem is I don't know how to draw the line in point 0.375, as you see below.
Please advise! Thanks!
#include <iostream>
using namespace std;
void draw(double min, double max, int n);
int main()
{ draw(0,1,8);
}
void draw(double min, double max, int n)
{ if (n != 1)
{ double mid = (max - min)/2;
cout << mid << endl;
draw(min, mid, n/2);
}
}
The program output:
0.5
0.25
0.125
Here's the expected output:
0.5
0.25
0.125
0.375
0.75
0.625
0.875 2 2460

shouldn't you call draw(mid, max too, n/2) ?

draw(mid, max, n - n/2);
n could be odd.
