    #include <algorithm> and use std::sort instead of implementing a quadratic time sort like selection sort.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    keep in mind that std::sort by default sorts in ascending order (smallest to biggest). To make it sort in descending order, you have to supply a comparison function.

    So what you are actually asking is for one of us to write a selection sort for you? That's not how it works here - you write the code, we explain what's wrong, how it works etc when you ask SPECIFIC questions.

    IIRC
    Code:
    procedure selection_sort (a, first, last) :
       while last > first :
          choose highest item in a from [first, last), called max
          swap a(max) with a(last)
          decrement last
       end while
    done
