Are you familiar with makefiles? the preprocessor?

This might be a suitable recipe for you.
1. Write a program to turn the contents of a text file into, say, a C or C++
file that contains the text of the file in question.
Something like a program that takes this (sample.txt) :-
This is the first line of sample.txt
This is the second line of sample.txt

And outputs something like this as something like sample.c:-
char *MessageArray[] =
{
  "This is the first line of sample.txt",
  "This is the second line of sample.txt"
};

Which can then be #included into your source code, ready to be compiled
along with the rest of your code,

The role of the makefile would be to generate the C source code before it
gets compiled, invoking a utility program (written by you) to turn
sample.txt into sample.c.

HTH,

Ian
