C++ Programming Tutorials: 13 Functions - Passing Variables by Value or Reference

Link to the Complete C++ Tutorial Playlist:

In this video C++ Programming Language Tutorial video we will look at some more advanced level function concepts in C++. We will talk about passing variables to functions using value or reference. There is a critical difference, and it must be understood to move on to higher grounds in C++

Sending thanks from 10 years later. Your explanation was very helpful and I understand the topic now. Again, thank you!

Taking my first embedded class and found this video. I wasn't confident with functions being passed by value, therefore I did not understand how to write my hw code. I watched this video right now (1:30am) and not only did I feel much better on the topic but, I also was able to write code and complete my hw understanding everything I did. Truly, thank you. This video was put up 8 years ago and is still saving students. Thank you.

I applaud you for repeating and leaving in the errors. This makes it realistic and less frustrating to learn. Good teacher!

Thank you so much. I watched other videos where I got all the basics and still didn't get it. I finally understand and you made it so simple. You really helped me a lot.

Spent an hour trying to get this information. So glad I found this video!

[Raulz]

Thanks very well explained. Just finished my Programming Fundamentals class and these videos are great as a refresher.

Thank you so much for this tutorial....You don't jump around topics and you present the material very thoroughly. I appreciate it. =)

Because you are shipping variables outside of the main function. When they come back to main, I want the modified versions to come back. Then I can resend them out with updated values. You need ampersand sign anytime you want to modify the ACTUAL variable.

Amazing video. Was trying to find something like this for a few hours because I just wasn't figuring out how to do it. Currently in an intro course and I'm jumping ahead and trying to make a slightly complicated math practice program using the basic arithmetic operations. This is hopefully the final key I need to really build the design I want. Though I do need to figure out how to stop the program from breaking when a char is entered instead of an int. lol

This is the best tutorial I've seen for udf variable ever! Thank you!
