Login Using a Text File in C

While I'm writing my book on C programming I came across with the idea to include in my book topic on File Handling in C.  The idea is to write a program using C as my programming language to store a username and password in a text file and create a login program that will ask the user to give the username and password. The program will search for the username and password that is already stored in our text file. In this example the name of the text file is users.txt. I

If the username and password are correct and can be located in the text file the program will allow the user to access the system. But if username or password is incorrect the program will not allow the user to access the system. I hope you will find my work useful.  Thank you.
