help a noob, deleting multi dimentional arrays

Question

hi, how do you delete a multi dimentional array?

example:

char** buffer = new char*[100];

for (int i = 0; i < 100; i++)
    buffer[i] = new char[50];




how do I then delete this?

is it like this?

for (int i = 0; i < 100; i++)
    if (buffer[i])
delete [] buffer[i];



or like this?

for (int i = 0; i < 100; i++)
    if (buffer[i])
delete [] buffer[i];


thanks for your time

// to delete those:
for (int i = 0; i < Rows; i++) {
  delete [] buffer[i];
  buffer[i] = 0;
}
delete [] buffer;
buffer = 0;
