 | Lots of good Tic Tac Toe threads on Daniweb. There are a variety of ways to approach it. Break it up into smaller, more manageable tasks. For instance, I would start with a function that accepts input from the human player. You should probably make it a member function of … |
| | Okay, so you have functions that encrypt and decrypt. Both of these functions take a parameter called choice, which isn't used. You talk about files, but I see no ofstreams or ifstreams. There is a password that I assume is not encrypted and which functions as the encryption/decryption key. Presumably … |

Let's let liberals/progressives define themselves, and conservatives likewise. But seriously, this reeks of such intolerance, I cannot fathom anyone labeling this "progressive" or "liberal".[/QUOTE] The Republican Party has successfully redefined liberal and progressive to the point that, whatever it … |
