Thread: Not Going Through If Statements

I just decided to re-write it anyway, using a two-dimensional array for the calculations.

Code:

#include <iostream>
#include <cstdlib>
#include <string>
#include <cstring>

using std::string;
using namespace std;

int main()
{

system("title Metric Converter");

 cout<<"Simple Metric Conversion Program\nWritten By:Relyt_123"<<endl<<endl<<endl;

  int convertfrom;
  int convertto;
  string arrayone [11];
  double arraytwo [11][11];
  int number;
  double answer;


  arrayone[1]="Metric Ton";
  arrayone[2]="Kilogram";
  arrayone[3]="Metric Pound";
  arrayone[4]="Hectogram";
  arrayone[5]="Dekagram";
  arrayone[6]="Gram";
  arrayone[7]="Decigram";
  arrayone[8]="Centigram";
  arrayone[9]="Milligram";
  arrayone[10]="Microgram";
