alphanumeric sorting order of strings in C [duplicate]

Natural sort in C - “array of strings, containing numbers and letters”

When sorting strings in C with qsort and strcmp I have the problem that alphanumeric entries, typically strings ending with numbers, are being sorted oddly like this:

• Entry1
• Entry12
• Entry2

The desired behavior is this:

• Entry1
• Entry1_new
• Entry2
• Entry12

What is the easiest way to do this?

Thanks

There's nothing odd about the sort; '1' comes before '2', so any string that has 'Entry1' will come before any string that has 'Entry2'. That's just the way strcmp is defined. If you desire a different sort order, you can always write a different sort function.
