When a file has been opened using the 'r' mode specifier, which method will return the file's contents as a string?

Assuming we're talking C here:

I would opt for fread () with the following notes:

- there are no guarantees that the whole file counts as one string.

- you need to know the length of the file to allocate enough memory.

- you need to append a trailing 0 in memory to terminate the string.

fgets () does return a 0-terminated string but is not exactly what is asked since it only reads until the next newline character which may be in the middle of the file.
