fprintf to text file

Ok, I've got a text file say like below:

Imperial Imperial
1 0001010000000000000000000000 5000
0 0
ROOF BASICS
22 96.000000 0.463648 0.000000 12.000000 12.000000 1 1 1
4.163119 4.163119 3.500000 3.500000 3.500000 3.500000
0.250000 0.250000 24.000000
0.000000 0.000000


Two things are causing me a problem. I'm not sure if the problem is being caused by my \n or what but if anyone can offer any suggestions, that would be great.

1) If I change the 22 to 3 in line five, I close the file and wind up with 32. How can I get rid of the 2 and truncate the remainding text to allow only one space between data.
2) When I modify line six, I end up with line seven missing 0 in 0.2500000 (looking like .2500000)

Thanks,

You are trying to process the file as a binary file, but the format of the file is sequential text. There is another thread from recently that goes over processing a file in binary...I wont rehash it here. I think the thread is called "Deleting/Searching Directly File I/O", it is about a page back if you look for it.

here is a link to the mentioned thread:

http://cboard.cprogramming.com/showt...threadid=34807

There is a wealth of file i/o information here on the boards, a quick search may prove to be all you need.
