Keep in mind, when using malloc on something, use free to free the allocated memory when you no longer need it.

Thanks man You really made my day

[@elisha502]

Magic, you need to call Harry Potter. I'm actually wondering the same thing.

[@LexElls]

Thanks for supplying the code! That's awesome

You're welcome Lex! :-D

[@avixx]

Love this!

[@mementomori7160]

I know it's old but, why can't the compiler jsut dereference the pointer first? Do you know if there is a reson for that? That way they wouldn't need a completely new operator to exist

[@ladyville3]

It would do it all the time, even when you don’t want it to?

[@jeremykhoo5127]

Sometimes you want to change the address of the pointer and not the value
You have an address to a John's house. Set to Mary
A postman subroutine has a pointers to "delivery for" it is set at adress: John's house
Person: Marry
So it means you will go to John's house and deliver the package to Mary who lives there
If you always dereference that means you can only deliver to the people in John's house (Mary and John). You cannot deliver to anyone in Clements' house
ie you can only change the value, you cannot change the address

Very well explained. Thanks

thanks man. I finally get it 😅

[@SameerAhmed-wf8yf]

which IDE are you using?

[@erennkose]

Thanks for these videos i hope i can pass my exams.

[@PortfolioCourses]

You're welcome Aaron, and good luck on your exams! :-)

[@marbles5590]

Thank you for this video... although I had problems in my code. It says 'cannot convert int* to Point'. I don't have any problems using the arrow operator and such, only this (*p3), p3-> thing after dynamically allocating using malloc().

[@PortfolioCourses]

You're welcome! :-) And I'm not sure why that would be without seeing the code, can you maybe post your code in a comment here so I can look at it? I've posted the code in this video here: github.com/portfoliocourses/c-example-code/blob/main/arrow_operator.c.

[@marbles5590]

@@PortfolioCourses hello, I used another IDE and the code works. My code is just the same as yours. Maybe this error has something to do with my settings...

[@Quasarsoft]

​@@marbles5590 I suppose you are using c++ compiler . You need to change your main.cpp to main.c

[@marbles5590]

@@Quasarsoft ty for that but i have already solved the prob months ago. Still there are times i get used to using the devc++ compiler and forgot to change it to .c 😅
