I am trying to get a program working, our professor gives us code but sometimes its a little rough and needs work. well i am declaring a function as follows bool solutionFound(set::const_iterator ) and the compiler says that dosnt follow the template. if i knew c++ better i could probably figure it out, but i dont know, or really care. if someone could smooth that line over so it works, i could appreciate it. ps. i know i need to know what type of set of const_iterators it is, but i dont. maybe its still fixable?
