Linux sort used for C++ program

Cn00b (5)
I am quite confused as I was told that I need to redirect the output to be the
input of the Linux sort program and sort the results from high count
to low. I haven't figured out this aspect of of Linux yet as I have only used it for going on a week now. If anyone could point me in the right direction as to how I would redirect my output it would be appreciated! Thank you!

The above will give you result in ascending order. to get the result in descending order use:
$ ProgramName | sort -r
