Here is one issue: void WaveTableManager::insert(WaveTable * WT,int position) { if (wtvector.size()<=position) wtvector.resize(position); wtvector[position]=WT; // < — Out of bounds access } When you call resize(), the upper bound is vector::size()-1. Since position is the new size of the vector, what you probably want is this: wtvector[position – 1] = WT; 5 solved can not … Read more

It would be more readable if you kept the code formatting for the whole code, not just its part. But when I tried to find a main function, I didn’t find any. Therefore there is no reference to main because you haven’t implemented one, at least not in the code you posted here. solved Error … Read more
