I have two dimesional char array [1000][30] that contains 1000 words 20 characters long. I want to go through and delete any of the 1000 words that is not unique- ie. those that are repeated. I don't have any idea how to code this can anyone help me?

Bob,

This is just 'one' technique that would work. Sort the array using qsort() then build a new array from the sorted one but ignore duplicate items when adding them to the new array.
