That would be because Brett forgot his morning coffee yesterday and made
at least two mistakes in his suggestions.
length1 = strlen(string1);
for (counter1 = 0; counter1 < length1; counter1++)
{
number1[counter1] = string1[counter1] - '0';
printf("%d", number1[counter1]);
}
printf("\n");
Try that instead. What you had before was a stack overflow. It was a
miracle the program didn't crash. This is the sort of thing that makes
it important to use Safe C++ across the board. That way we won't need
coffee.
