How to remove first element in multidimentional array?

I can't make my array print. The first element prints but it will not print the remaining. Need out of bounds error on negative index?

• #include <iostream> using namespace std; class myArray { public: myArray(int n) { start = 0; arrayLength = n; array = new int[n, 0]; for (int i = 0; i ...show more

• Answer:

  First, it makes no sense to test if index < 0 after it already was tested to be greater than 0 on the first if statement... Second, you shouldn't be using int for indexes you should be using size_t which is an unsigned integral value... there are no negatives All the object has to do is keep track of size (your arrayLength variable), if an index comes in larger than the size then throw an error, otherwise return the value at that position. EDIT: Same applies to your constructor... use size_t or else you'll need to check for negative values there too, and everywhere else. EDIT2: oh and for the love of everything holy please please please add a destructor and delete[] your array EDIT3: as far as allocation goes... if someone passes a negative number the actual value is HUGE and will through a bad_alloc error surround your new allocation with a try catch block to see if someone is trying to allocate more than the OS will allow or set an arbitrary max size and check it before attempting to allocate the memory.
