slow runtime

[Dr. Smith]

Jonathan, thank you for the quick response.  I made some changes as you suggested
and got much more speed. For some code that I'd like to convert to D, I am
exploring the pros and cons of constructing a class library (versus a C like
function library). My code here is just part of that exploration.

... the improved calling code ...

import std.stdio, std.string;
import testlib;

void main() {

  classtest obj = new classtest;
  double[][] a = obj.hit;
  double[][] b = obj.hot;
  string c = obj.stest;

  int i, j;

  for(i = 1; i < a.length; i++) {
    for(j = 1; j < a[i].length; j++) {
      writefln("%s\t%f\t%f", c, a[i][j], b[i][j]);
    }
  }
}
