What am I doing wrong here in my c++ ?
I haven't studied this too carefully, but this line doesn't do what you think it does:





//Call function chop





void chop(int%26amp; head, float%26amp; tail);





You're not calling the function that you declare later in the file. You should call it this way:





chop(chipmunk, head, tail);





Also your chop function doesn't do what you think it does. You're assigning head to chipmunk but there's nothing in head when it is called.
