What is pointer What are the advantages of using a pointer?
(i) Pointers make the programs simple and reduce their length. (ii) Pointers are helpful in allocation and de-allocation of memory during the execution of the program. Thus, pointers are the instruments of dynamic memory management. (iii) Pointers enhance the execution speed of a program.
What are pointers in programming?
In computer science, a pointer is an object in many programming languages that stores a memory address. This can be that of another value located in computer memory, or in some cases, that of memory-mapped computer hardware. A pointer is a simple, more concrete implementation of the more abstract reference data type.
What is the advantage of using pointers in C Mcq?
Pointers enable complex “linked” data structures like linked lists and binary trees. Question 10 Explanation: See below explanation (A) With pointers, address of variables can be passed different functions can use this address to access the variables.
What is the use of pointers Mcq?
The function fun() expects a pointer ptr to an integer (or an address of an integer). It modifies the value at the address ptr. The dereference operator * is used to access the value at an address….
| A | Pointers allow different functions to share and modify their local variables. |

| D | All of the above |
Which of these are reasons for using pointers Mcq?
Discussion Forum
| Que. | The reason for using pointers in a C program is |
|---|---|
| a. | Pointers allow different functions to share and modify their local variables. |
| b. | To pass large structures so that complete copy of the structure can be avoided. |
| c. | Pointers enable complex data structures like linked lists and binary trees. |
Why pointer is important in C?
Pointers allow us to perform dynamic memory allocation and deallocation. Pointers helps us to build complex data structures like linked list, stack, queues, trees, graphs etc. Pointers allow us to resize the dynamically allocated memory block. Addresses of objects can be extracted using pointers.
