File I/O in Erlang allows you to read from and write to files in the file system. Here are the basic steps to handle file I/O in Erlang:Opening a File: To start reading from or writing to a file, you need to open it using the file:open/2 function. This function takes the filename as a string and the mode as an atom. The mode can be read, write, append, read_write, or write_append.
Reading from a File: To read data from a file, you can use the file:read/2 or file:read_line/1 functions.
