Firstly you have an error in the code, you mean to have Thing *thing(new Thing());, and only return thing;. Use shared_ptr<Thing>. Deref it as tho it was a pointer. It will be deleted for you when the last reference to the Thing contained goes out of scope. The first solution ...
Thus, if you want to return a pointer to a list of pointers-to-const, what you must have is a list of pointers-to-const. But you don't have such list. You have a list of pointers-to-nonconst and those list types are not interconvertible. Of course, you could transform ...
A pointer always has whole numbers stored in it because it stores the address, and the address can't be negative or a fraction. A pointer is always initialized to null, and the value of a null pointer is 0. int *p = null; Then, we give it the address we want for no confusion as...

Actually I am not able to debug the code as it is for the device and running a big code, so i am putting logs and message boxes. In the message box code I have shared the value is coming to be zero. So I am a bit confused...
The equivalent of the first line, in VB is: VBScript dimptr as long'int * ptr; This was easy because it follows from the definition of the pointer. A pointer is just a variable whose value is the address of another variable. It islongbecause a pointer in MS Windows is 4 bytes. ...
The following code shows the scenario where thechar*pointer is assigned a value returned from themalloccall, but later in theelseblock, the same pointer is reassigned with a string literal. This means that thec_strvariable points to the location that is not a dynamic memory region; thus, ...
Hello, can anyone tell me how to pass an array to a function ? I have this function , part of my class. It works if I do not put in int a everywhere , but obviously , I need to add an array so I... C / C++ 110 Pass-by-reference instead of pass-by-pointer = a bad...
Note that I want to move the mouse pointer, not *find *the mouse pointer. We already tried the "Show location of pointer when I press CTRL key" setting. It's more of an annoyance than a help for this user.(And yes, I suggested logically aligning the monitors in a straight line...
