Question

All I want is to read a *.c file, remove the header, change the header and save the file of course in *.c format. I used “fprintf”, the problem is in the *.c file there is some printf with “\n”, and the fprintf interpretes it like a new line :(, I ended up with a broken *.c file.
Is there a way to handle *.c files with matlab commands ?

Answer 1

Once you have read the file, you should replace the \ character with \\, which will be converted back to \ when writing again to file. strrep is great for this:

str = 'a\nb';
str = strrep(str,'\','\\');
fprintf(str)

a\nb

(note that fprintf without file identifier prints to command line. Very useful for debugging)
