Question

Practice 4 ways of allocating/deallocating memory in an array

Answer 1

There are four ways to allocate and deallocate memory in an array - static allocation, dynamic allocation, stack allocation, and heap allocation.

Step-by-step explanation:

Allocating and deallocating memory in an array can be done using various methods:

1. Static allocation: In this method, memory for the array is allocated and deallocated automatically by the compiler. The size of the array is fixed at compile-time.
2. Dynamic allocation: This method involves using functions like malloc() and free() in C or new and delete in C++ to dynamically allocate and deallocate memory for the array. The size of the array can be determined at runtime.
3. Stack allocation: In some programming languages, arrays can be allocated and deallocated on the stack using array declarations without the need for explicit memory management. The size of the array should be known at compile-time.
4. Heap allocation: This method involves allocating and deallocating memory for the array on the heap using heap memory management functions like malloc() and free().
