Dynamic memory program with explanation? ?

#include <iostream>

int main() {

int size;

// Prompt the user to enter the size of the array

std::cout << "Enter the size of the array: ";

std::cin >> size;

// Allocate memory dynamically for the array

int* array = new int[size];

// Prompt the user to enter elements for the array

std::cout << "Enter " << size << " elements for the array:\n";

for (int i = 0; i < size; i++) {

std::cin >> array[i];

}

// Display the elements of the array

std::cout << "The elements in the array are:\n";

for (int i = 0; i < size; i++) {

std::cout << array[i] << " ";

}

// Deallocate the dynamically allocated memory

delete[] array;

return 0;

}

Explanation:

1. The program begins by declaring an integer variable size, which will store the size of the array that the user will input.
2. The user is prompted to enter the size of the array using the std::cout and std::cin statements.
3. Memory is allocated dynamically for the array using the new operator. The new operator returns a pointer to the first element of the allocated memory. In this case, the int* variable array is assigned the memory address of the dynamically allocated array.
4. The user is then prompted to enter the elements for the array using a for loop. The loop iterates size times, and each element is assigned to the corresponding index of the dynamically allocated array.
5. After the user has entered all the elements, the program proceeds to display the elements of the array using another for loop.
6. Finally, the delete[] operator is used to deallocate the dynamically allocated memory. It's important to deallocate the memory to avoid memory leaks.
7. The program ends with the return 0; statement
