[redhead]

are you looking for something like this:

#include <iostream>
using namespace std;

int main (void)
{
  cout << "ASCII Table times 3" << endl;
  int i,n;
  const int array = 256*3;
  char arr[array];

  for(i=0; i<array; i++)
   arr[i] = i%256;
  for(n=0; n<3; n++)
  {
    for(i=0; i<256; i++)
     cout << (char) arr[i];
    cout << endl << endl;
  }
  return 0;
}
