Question

How can I read multiple lines from a text file (variable width) and store all of them in a C “string”?

EDIT: I guess I’ll be fget’ing the strings and storing them in one flexible buffer (via realloc) 🙂 Also, this is not homework even though it apparently seems so (programming is just a hobby for me). I was just asking out of curiosity

Answer 1

Here’s the general process

1. Create an initial buffer.
2. Read a line from the file, or up to the remaining space in the buffer.
3. EOF? Skip to 6.
4. Filled the buffer? Reallocate with more space.
5. Rinse and repeat.
6. Add a terminating 0
