Which among the following is true the pointer to object can hold address only the pointer can hold value of any type the pointer can hold only void reference the pointer can’t hold any value?

Which among the following is true the pointer to object can hold address only the pointer can hold value of any type the pointer can hold only void reference the pointer can’t hold any value?

If you’re getting the REFERENCE BY POINTER blue screen of death error on Windows 10 or 11, it’s likely that a faulty RAM stick, third-party software, outdated drivers, or corrupt system files are to blame.

Right-click Start, then select Device Manager.
Right-click the driver, then select Uninstall.
Restart your laptop to automatically reinstall the drivers. Make sure that you update the driver after re-installation.

Which among the following is true the pointer to object can hold address only the pointer can hold value of any type the pointer can hold only void reference the pointer can’t hold any value?

Explanation: The address of the type just defined by the class may imply its address stored in the target pointer. The addresses do not differ, but remember that they differ in the amount and type of memory required when viewing objects of different classes. Therefore, the object pointer must belong to the same class as before.

When one object reference variable is assigned to another object reference variable then a copy of the reference is created a copy of the object is created a copy of the reference is not created it is illegal to assign one object reference variable to ano

(C) Copies will not be made. (D) An application is not allowed to assign an object reference variable to another object exploration variable. Explanation: If an object’s learning resource variable is assigned to another link target variable, a copy of the link is created.

What is pointer where it is used pointer to pointer and pointer to function explain by giving example?

A pointer is a variable that makes it easy to refer to another variable. Unlike other variables, which contain values ??created by a particular type, a pointer contains our own variable address. To illustrate, an integer variable (or your whole family might say stores) has an integer value, but an integer pointer sees the address of the integer variable.

What is dangling pointer a pointer pointing to NULL pointer pointing to memory location which has been freed pointer which is pointing to new location none of these?

A dangling pointer is often a situation where memory has indeed been dynamically allocated to a variable and/or after use the internal memory is freed, but when the pointer is reused if it still opposes the previous position then the application is called a dangling pointer. or possibly a dangling pointer.

Which of the following statements is correct * pointer to derived class Cannot be created derived class pointer Cannot point to base class pointer to base class Cannot be created base class pointer Cannot point to derived class?

b) Derived class pointers usually do not point to the base class. c) Pointer and derived class cannot be executed. d) Pointers to the base class are not created. The correct answer was “B”.


What are the advantages of reference variable over pointer and pointer over reference variable?

Difference between a reference variable and a default variable Because references cannot be null, they are safer to use. A pointer can be reassigned while it cannot be referenced and should only be assigned at initialization. A pointer can be directly assigned to NULL, but it cannot be referenced.
