You are increasing code each time you read a character, and you return code back to the caller even though it is no longer pointing at the first byte of the memory block as it was returned by malloc.

You are casting the result of fgetc file to char. You need to check for EOF before casting the result to char.

Improve this answer. Matt Whats the easiest way to count the number of characters in a file so I can set the "" to that? Also I'm not exactly sure what you mean by number 2, I understand that i'm doing it wrong in that way, but how would i amend that? You meant fgetc perhaps?

Can you explain how fseek and ftell work? I would think you would need some kind of loop to count the characters of the file. Think of fseek as a way to reposition a cursor.

That gives you the size of the file. If you do not do that, you will start reading the file from the end, which will cause errors and ruin the entire operation.

Headers are the public interface to your module, so they should contain the declarations of the public functions and possible variables. The C source file is the private part of the module that actually contains the implementation.

Then, with your main program in myprog. Granted, that is not likely to matter much, since if malloc fails your program might not be able to continue anyway. But still. Make sure to fclose file on every error exit after opening the file, either in every single place where you do an early return , or by collecting the cleanup code and return to a single place.
