Windows 11 error link in BSoD notification is usually due to faulty drivers or files. One solution is to update drivers manually and automatically using a dedicated application. Don’t miss our stories showing how to enter Safe Mode in different ways.

Windows Reference_By_Pointer error is one of the most difficult types of BSOD (Blue Screen of Death) to fix and diagnose. This issue has been prevalent in Windows 10 and we are starting to see better user reports in Windows 11 as well.


Corrupted or outdated graphics drivers can cause a lot of problems on your computer. Your current pointer closing link error code is one of them. Update outdated graphics drivers by following the instructions below. Step 1: Press the Windows key R + to open any Run window. Type devmgmt.And msc but press Enter.

When the reference_by_pointer message appears, Windows sees the wrong number of reference points for the running object. Because this can be a real security issue, Windows shuts down and displays a BSOD, forcing your system to reboot and wiping all active disk space during the process.

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: Only the address of the specified class, which is stored in the object pointer, can enter its discussion. The addresses do not differ, but they can differ in the amount and style of storage needed for objects associated with different classes. Therefore, the same target class pointer must be used.

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

You do not need to make a copy of the certificate. (D) It is illegal to assign an object reference variable to another object reference variable. Explanation: If an object reference variable is maximally assigned to another object reference variable that you simply copy, the reference is often 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 stores the address of another variable. Unlike other variables, which contain a specific type based on values, the pointer side refers to the address of the variable. For example, an integer variable continues (or, one might say, stores) the primary integer value, and an integer pointer holds the address of the integer being changed.

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 suspended pointer is a situation where memory has been dynamically allocated due to a variable, and after the current memory usage, the memory is freed only when the pointer is reused, it must always point to the last digit, then it will be considered stuck. Marked pointer or free hanging 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) A derived class pointer must not point to a base class. c) It is not possible to create a pointer to a derived grouping. d) It is not possible to create a pointer to a class set belief. The correct answer is “B”.

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

Difference between a reference variable and a pointer variable Since references cannot be NULL, they are safer to use. A pointer can be reassigned while a reference cannot be permanently assigned on initialization. A pointer can be completely NULL, but a reference is not.

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: Only props of the specified class can get their stored address using an object pointer. The sentences do not differ, but differ in the amount and type of memories needed for the objects of the different manuals. Therefore, the same class object pointer must be used.

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) that is, no right to reproduce the link is created. (d) This is when you want to illegally assign an object reference to another object reference variable. Explanation: Normally, when an object reference variable is reassigned to another object reference, a copy of the reference point is created.

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

A pointer is definitely a variable that holds the address of another variable. Unlike other properties that contain mode values, a particular pointer contains the address of a variable. For example, a large integer variable (or you can expose memory) holds an integer value, but an exclusive integer pointer holds the address in 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?

Dangling pointers can be a situation where memory was still dynamically allocated to a variable, then after using the memory, someone’s memory is freed, but when the index is reused, if it still leads to the previous location, we become hands referencing hands that both hanging and free.

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) A derived class pointer cannot return a base class. c) A pointer to a derived symbol could not be created. d) An array-based pointer cannot be created. The correct alternative is option B.

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

Difference between a reference variable and a pointer variable Since references cannot be null, they are definitely safer to use. A pointer can be reassigned, but a reference cannot, and must be assigned at initialization. In particular, pointers can be set to NULL, but references can’t.
