Answer 1

You use a counter type of algorithm to convert to a string. I got this technique from programming Commodore 64 computers. It is also good for game programming.

• You take the integer and take each digit that is weighted by powers of 10. So assume the integer is 950.

  • If the integer equals or is greater than 100,000 then subtract 100,000 and increase the counter in the string at ["000000"];
    keep doing it until no more numbers in position 100,000. Drop another power of ten.

  • If the integer equals or is greater than 10,000 then subtract 10,000 and increase the counter in the string at ["000000"] + 1 position;
    keep doing it until no more numbers in position 10,000.

• Drop another power of ten

• Repeat the pattern

I know 950 is too small to use as an example, but I hope you get the idea.
