Hey, we just started learning functions in class. We were given a project to complete. I'm trying to work out the errors, but I'm stuck with
error C2084: function 'void bubblesort(int [],int)' already has a body
error C2084: function 'void print(int [],int)' already has a body
error C2084: function 'void printH(int [],int)' already has a body
How do I call the functions differently to get them to not conflict?
