How to delete this 2d dynamic array in c++

Question

bool **arr=new bool* [row];
for(int i=0; i<9; i++)
{
    arr[i]= new bool[column];
}

I want to delete this dynamic array because it cause a problem with my RAM.

As a side note you should probably replace 9 with row to allocate each row, not just the first 9. — flogram_dev

You just delete in the reverse order it was allocated:

for(int i=0; i<9; i++) {
    delete [] arr[i];
}
delete[] arr;
