When writing to a text file, be sure to use the correct line-ending character! Unix systems use \n, Windows systems use \r\n, We will be using 4 commands to open, read, get data and close a file.
The “fopen” opens a file for you. You will use the ‘r’ qualifier to tell the filesystem that you are opening a file. The “fgets” command gets all of my data from a file that I setup to be read.
The “feof” command checks for the end of file. The “fclose” command tells the filesystem that you want to close the connection.
Here, I am providing you with a PDF document. This document has all of the examples with explanations.
