Ty,
Try this instead:
void ReverseArray(char Input[], char Reversed[])
{
  int i;
  int x;
  int Index;

  // Get the index of the first null character
  for(x = 0; x < 50; x++)
  {
    if(Input[x] == '\0')
    {
      Index = x;
    }
  }

  // Assign values to new array in reverse
  for(i = 0; i < Index ; ++i)
  {
    Reversed[i] = Input[Index - 1 - i];
  }
}
If you compare the code above to the code you posted you will notice that I use Index instead of x because x will always equal 49. I also removed the line where you decremented the x (which should have been the Index variable) variable.

Hope my code works.

>I am having a problem reversing the values in an array. The program I'm writing asks the user to enter a word, then I call the ReverseArray() function to reverse the values and cout the word backwards. When printing the reversed array to the screen, I get a bunch of odd sequencial characters. This is the syntax for my ReverseArray() function.

Semper ubi sub ubi.
