The more the numbers, the more the if-statements that will be required to sort the numbers. use of "else" and "else if" may help. You should be using <= instead of < (what if two elements are the same?). Thanks for the answer, the problem is when i type 2 same numbers, I don't think that's a useful "popular method". That procedure is called merge-sort (while the above procedure is called insertion-sort). For three values, the easiest is to implement a bubble sort which shouldn't be really slower than other algorithms (when you want to sort more values, it becomes horribly slower though). so I can sort all the ways except using the if statements. however, if there is a way using this method I would love to know.
