Re: [Dev-C++] Question!!

[Per W. <pw...@ia...>]

Trivial exercise. You have a static buffer large enough never to overflow
for the numeric range you receive as input.

You fill in the buffer from the end by taking your number modulo 10 to
find one digit. Then number divided by time to shrink the number.

Continue until number is zero.

Observe to take special care if number was zero from the beginning.

Also take care about negative numbers. Easiest is to set a flag that is
was negative and then negate it and perform above algorithm. In end, check
flag and if needed add a '-' to the buffer.

Return the pointer to the first used character in the buffer.
