What is diffrent between object pointer and this pointer?
'this' is an object-pointer: it points to the current object (usable only in non-static methods).
When you let your pointer linger over an object the pointer is?
The pointer is non-NULL.
When does this pointer get created?
When we call non static method with respect to class object then this pointer is created which keep the reference of that object.
Where string is stored on Heap or Stack in java?
A String is treated as an object, meaning there is an object on the heap. Of course, the variable you define is a pointer to the object, and it is stored on the stack.A String is treated as an object, meaning there is an object on the heap.

When putting an object on a spring scale the pointer shows the object's what?
When putting an object on a spring scale the pointer is going to show that objects weight. So the answer would be WEIGHT. Like for example when you are in your bathroom and you step on the scale , the pointer is going to show how much you weigh.
Which pointer do you use to resize a chart object?

Definition of dangling pointer object?
A dangling pointer occurs when objects have been deallocated or deleted from the system. They 'dangle' due to the pointer's values still remaining leaving a location to the non-existent object in the memory.
What is an array of pointers to pointers?
A pointer is a variable that stores value of address of a variable. Since a pointer itself is a variable, it is allocated a memory location.Pointer to pointer means a pointer which points to the address of a pointer. In other words a pointer to a pointer has the address of the address of a variable.We can have pointers to int, and pointers to char, and pointers to any structures we've defined, and in fact pointers to any type in C, it shouldn't come as too much of a surprise that we can have pointers to other pointers. If we're used to thinking about simple pointers, and to keeping clear in our minds the distinction between the pointer itself and what it points to, we should be able to think about pointers to pointers, too, although we'll now have to distinguish between the pointer, what it points to, and what the pointer that it points to points.
What is 'this pointer' in regards to computer programming?
It is a pointer which is pointing to present object with which the memberfunction is called in c++ language.
How this pointer works in C plus plus?
The "this" pointer is a pointer to the instance of the object, with scope within a member function of that object. It is not always necessary to use it, as references to variables defined in the object will be implicitly prefixed with "this->", but it can resolve name scoping problems, and it can make the code more readable.
Why do you use double star '' in initializing a variable in class?
The double star (**) notation is not specific to initializing a variable in a class. It is simply a double indirect reference to an object.float myFloat; // an objectfloat *myFloatPtr; // a pointer to an objectfloat **myFloatPtrPtr; // a pointer to a pointer to an objectmyFloat = 123.456; // initialize an objectmyFloatPtr = &myFloat; // initialize a pointer to an objectmyFloatPtrPtr = myFloatPtr; // initialize a pointer to a pointer to an objectmyFloat; // refer to an object*myFloatPtr; // refer to an object through a pointer**myFloatPtrPtr; // refer to an object through a pointer to a pointer*myFloatPtrPtr; // refer to the value of the pointer to the objectDouble pointer notation is used where the caller intends that one of its own pointers need to be modified by a function call, so the address of the pointer, instead of the address of the object, is passed to the function.An example might be the use of a linked list. The caller maintains a pointer to the first node. The caller invokes functions to search, add, and remove. If those operations involve adding or deleting the first node, then the caller's pointer has to change, not the .next pointer in any of the nodes, and you need the address of the pointer to do that.
What is dangling pointer reference in c plus plus?
A dangling pointer (we also use the terms stray pointer and wild pointer) is created whenever we call delete on a pointer and then try to use the pointer without reassigning it.We can also create dangling pointers inadvertently by calling a rogue function that returns a pointer to an object that is local to the function we are calling. The object will fall from scope when the function returns so the pointer is left dangling.Note that there is no such thing as a dangling pointer reference. Pointers and references are not the same. A reference is merely an alias to an object -- it consumes no memory beyond the object it refers to. Whereas a pointer is a variable that may contain the address of an object, but it requires additional memory to do so (4 bytes on 32-bit architecture). Pointers may be NULL, references can never be NULL. Pointers to valid objects require indirection, references do not. References are the preferred method of accessing an object's members, not least because they are easier to work with.
