how to order a set of number

[sakurasyi]

hai...

i'm doing a simple program where it will sort a set of number from 1 to 100. for 1 to 9 it sort correctly. but after number 9 (10,11,...), the sort become 1,10,11, 12...,2,20,21,..and so on. Can somebody tell me how to sort it correctly?

thank you..

looks like you are doing a text sort rather than a binary sort. In a text sort each character of the number is considered in turn so for the numbers 10 and 2 the first characters are 1 and 2 and 1 < 2 therefore 10 < 2. A binary sort will compare the actual value of the number that is compare 10 with 2 therefore 2 < 10.

You have not mentioned what system you are using but you need to make sure that you are doing a binary comparison, possibly by converting the text to binary data first.
