C++ Pointers and References FULL Guide

In this video, I will show you why pointers are important to the C++ language, how they work, and how to use them. Then, I will show you why references are used and how they help reduce pointer usage.

I wish KZbin had option of liking content multiple times similar to claps on medium, This nearly hour long video must have taken you a lot of effort Thank you so much for sharing this💙

[@VelcodeCS]

No problem! Glad you found it useful!

[@p4c0m1r]

THANK YOU DUDE!!!🙏

[@wesleygilbert6422]

This definitely filled the gap in my brain with understanding pointers and references, thanks for your thorough explanation! Will be sure to share this with people that are struggling with this as well

[@VelcodeCS]

Thanks! When I was learning these concepts I remember guessing * and & until the program compiled and worked 😅. Once I learn how exactly it works behind the scenes, it became second nature. Glad this video helped and thanks for sharing!

[@jin6086]

Your content is amazing, keep up the good work!

[@VelcodeCS]

Thanks, will do!

[@loveshamie1351]

Thank you very much... I watched all of it. I understand pointers and references now. Love from Zimbabwe 🙂🙂 ❤

[@VelcodeCS]

Hello to Zimbabwe!

[@garipprogrammer8128]

man, you are the best.

[@patriciamendezlorenzo8747]

it is great, just great video😃

[@jexyl8071]

Goddamn man idk why no one else was able to emphasize the difference between swapping values vs swapping addresses. Copies! Having the same value in multiple addresses, yes - I can see that being problematic and inefficient once you scale up. Jesus! Thank you for this video

[@VelcodeCS]

Yeah, once that clicked in my brain. I was like, why does no one teach it like that?! Well, at least, no one I know. Glad it helped!

[@ashm7380]

Thank you for taking the time to make these videos. Please continue. You make a big difference in my learning , Thank you again.

Love you Brother from India

[@VelcodeCS]

And from Mexico over here!

@@VelcodeCS Love Mexico 💫

[@vedatduhadaglar960]

This was really helpful my friend, keep it up

[@VelcodeCS]

Thank you 😊

[@EstebanMartinez-pm2zc]

That thumbnail!!! 😅😂

[@nsociety]

37:39, is that code correct? int assigned to x pointer to int?

[@VelcodeCS]

Yes, it's correct, both x and y are integer pointers. The * dictates that it's a pointer and it also is used to read/write to the location it's pointing to. Hence, x is a pointer variable and the value 5 is assigned to where x points to.

[@lopo8000]

how much are u into cryptocurrency As a programmer?

[@VelcodeCS]

I myself have not been involved with crypto at all. I'm interested in how the block chain works, but not so much into the currencies themselves.

[@abdosayed4376]

Hi, could you please give me any of your social media accounts, also I really liked your C++ videos they are amazing bro
