(C++) delete[]

Keyword related to delete. It frees the memory dynamically allocated to an array.

include <iostream>

int main()
{
  const int arraySize = std::rand()%100;
  int * pArray = new int [arraySize];
  std::cout << "Created an array size " << arraySize << std::endl;
  for (int i=0; i<arraySize; ++i)
  {
    pArray[i] = i*i;
    std::cout << i << " : "<< pArray[i] << std::endl;
  }
  delete[] pArray;
  return 0;
}

Instead of using new[] and delete[], prefer a std::vector over an array by default (references 1 and 2).
