Printing from and to a stream

I have a basic question mabye.

is there a function in C that would allow you to read data from a stream to another stream. Or do you have to put the data in some kind of container like a struct or a array ?

Hmmm well i know how to read text data from one stream put it into something and then write it back to another one. What im lookiing at is if there is a way to move binary data from one file like an .exe to another .exe file. Now this will probably lead somone to saying we wont tell you how to make a viurs or something to that affect. Im just curious if its even possible in C to move data from one binary file to the begining or end of another binary file. Or is this something that can only be done in assembly ?

Yes, definitely. Just open the file using fopen() in binary mode, if you're on Windows. (In Unix, it doesn't matter.) Then just use fgetc() and fputc(). C char types are bytes, so it works just as you would expect it, for copying binary data.
