One of the coolest things you can do through programming is to process data from a file. Once you know how to do this, you can get data from the internet or from other programs and write a program that processes that data for you. For example, in my programming guide, you will need to learn how to do this to read and process data from the transactions file that your credit card company can give you.

Want to automate something in your business? Write a program that can read a file and do all the mundane calculations for you. Want to build an application that needs certain configuration settings? Write a program that takes the configuration settings from a file. Want to build an application that saves and loads user data? Write a program that saves that data to a file and then reads that data at another time. Want to build a data analysis tool? Write a program that reads that data from a file and analyzes it. See the possibilities?

This tutorial shows you the functions that you need to open, read, and close a file on your computer. It is one of the most useful things you can get your program to do especially if you're just learning how to program. It gives you a lot of functionality and will open up many kinds of ideas for applications. Let's learn!

In this video, you'll learn:
-How to programmatically open a file
-Read the first line of data from that file
-How to have your application exit when something goes wrong

Hope this helps!
