little program, help needed

[CornedBee]

I need a small program, and I'm stuck.
The program should read in an entire file and remove everything between two control phrases (including the control phrases). It should then write the result to a new file.
The control phrases are:
//!!COMMENT marks the start
ENDCOMMENT!!// marks the end
Th program should be a console app called like this:
program srcfile dstfile

Is there anything available or has anybody got tips for me?
How do you get the file length? How do you edit the puffer?

Thx in advance

Have a look at the Stream I/O routines on msdn site
http://msdn.microsoft.com/library/de...eam_i.2f.o.asp
or if you want the more speedy variant, File I/O Reference
http://msdn.microsoft.com/library/de...lesio_4lf7.asp

I have a local msdn version, but I can't find the functions to get the file length. And the documentations of the STL and stream classes sucks. I can't find anything there.
Maybe you have function names that I can look up? Or should I switch to API calls?

To get the file length, first open the file using fopen(). Then use

fseek(Pointer to FILE structure,0,SEEK_END);
long filelength = ftell(Pointer to FILE structure);

Thanks, it's useless anyway because the file format sucks (it's not plain text), so I can't do what I wanted.
I'll know next time, so thanks anyway.
