The game of Sea Battle is just an exercise in Windows32 programming and a welcome diversion while compiling large projects. We used to play this game at school. You'd position your ships on a 10 by 10 grid. Your opponent would do the same. Then you'd start exchanging shots: "B-5," "missed!" "E-1," "hit!" until one of you would lose all the ships to enemy fire, or until the math teacher would notice. Now you can play the same game against the computer (just make sure your boss doesn't catch you). The size of the program is only 280k (most of it bitmaps and sound effects) due to the absence of MFC in its diet.
Whistle a melody and watch this program graph the pitch in real time. The Frequency Analyzer (download now) technically speaking performs a Fast Fourier Transform of the sound (you need a sound card and a microphone to use this program). What it means is that it analyzes your voice and splits it into its component frequencies. Watch patterns of speech, the harmonics of vowels and the noise of sibilants. The size of the program is only 148k! (zipped 74k) Can you believe that?! There are web pages that make you download more than that just to be able to look at them.
