read line by line from a file
How do I read line by line from a txt file.
Each line is variable in length with '\n' as the newline.
This is in C code.

Try using the fgets() function.

Hmm, I thought fgets() was deprecated because of null reading issues. Not sure, but I'd also look into using getline().
Not all systems support it, so sometimes fgets is your only option (although you can write your own getline using fgets). I think it is also a tad more readable (it is obvious from the name alone what its intention is).

I believe getline() is for C++, the poster requested C code.

it's not hard to write such function using fopen and fgetc in C. There were at least 4 ways of doing this in "Language C" (or sth like that, dunno, I've got polish version), best book I've ever seen.
