How to create a Two Dimensional dynamic array of integers?

int main()

{

int size;

  std::cin >> size;

int **array  = new int *[size];

for(int i= 0; i< size;i++)
{
    array[i] = new int[size];
}

return 0;

}

This will make size*size 2D array.

How to create a One Dimensional dynamic array of integers?

int main()
{
  int size;

  std::cin >> size;

  int *array = new int[size];

  delete [] array;

  return 0;

Don't forget to delete every array you allocate with new.
