The memos within the code describes my problem pretty well. I'm trying to find a way to enter the amplitude, and the pitch, of a 3 second sine wave, and output the data as a .csd file and run it. 

But when I do this the parameter's that I've just put in go away and 0 is used for both the amplitude and the pitch. What can I do so that everytime I run the program I can put in new parameters, and create a new .csd file with those parameters?

I'm only a couple days into C and may be getting too far ahead of myself. I was trying things with fopen () and fwrite() but gave up after a few hours of producing only errors. 

I would greatly appreciate it if someone could point me in the right direction!!

Hope to hear from you soon, and hopefully you'll hear a lot more from me soon, too.
