Short and to the point (Pointer ;-) Thank you! Your videos are true jewels!

Glad you like them!

Thanks for a nice explanation of the pitfalls of 'delete'

[@ProfessorHankStalica]

You're welcome

at minute 4:10, why does it return "talica" ? why does it not return the memory address of "t" in the array of characters ? I thought if we made return type char*, and put return p in the function, it should return the memory address. Pls clarify, thxxx very helpful tutorials

[@ProfessorHankStalica]

It does. cout starts displaying characters, one at a time, from the memory address you give it until it encounters the null terminator. So, in this case, we returned the memory address of the element containing t instead of the memory address of the element containing s.

thx for the valuable content!

[@chiyang3749]

in cout, the ptr should print the memory address of that character, but why it print the actual character?

listen to what he said (3:44)

good to know, thanks a lot!!!

[@ProfessorHankStalica]

Happy to help!

Why did we return nullptr when pointer p points at element which is storing null terminator . Is there a relation between nullptr and null terminator ?

[@sameaspastmueed]

Please this is confusing

[@sameaspastmueed]

Also, when the returned pointer to local variable my second cout statement remain the same even after the bar function was called . I beleive when i cout *p I should have gotten ! But instead I got the same value which was A. Why did this happen?

[@ProfessorHankStalica]

the function is returning a memory address of the element containing the target character or it is going to return nullptr. nullptr is designed for use with pointers and null terminator is a special character used with strings.
