Works like a charm... ppl using VS 2005/2008 Professional/Express Edition 1. must change to 2. add => using namespace std; before main

I am a beginner and this is my first attempt to convert a DAT file that I opened in Note Pad with your snippet. Please assist me further if possible, Thanks.

I added using namespace std; to get the cin & cout to work...code ran smooth and converted fine each character or integer entered
