My new favorite way of commenting out code blocks

/* Debugging, print out the array
for (int ii = 0; ii < sizeof(data); ii++) {
  if ((ii % 8) == 0) {
    cout << endl;
  }
  printf("%02X ", ((unsigned char *) data)[ii]);
}
cout << endl;
//*/

That last line is a single line comment that closes a multi-line comment. By adding or removing "*/" to the comment that describes the block, I can comment out the entire block. No more hunting for the proper point to close it at, just adding or removing the comment closure to the top line.

Of course, this doesn't work if there's a multi-line comment inside the code block.
