The C++ array pointer add function allows you to perform pointer arithmetic on arrays. This means that you can increment or decrement the pointer to navigate through the elements of the array. The resulting pointer can then be used to access or modify the corresponding element.

Here are some examples:

int arr[] = {1, 2, 3, 4, 5};
int* ptr = arr;

// Increment the pointer and access the second element
ptr++;
cout << *ptr << endl; // Output: 2

// Decrement the pointer and modify the third element
ptr--;
*(ptr+2) = 6;
cout << arr[2] << endl; // Output: 6

In this example, we first initialize an array `arr` with five elements, and then create a pointer `ptr` that points to the first element. We then increment the pointer once, so that it now points to the second element, and output its value. Finally, we decrement the pointer and use it to modify the value of the third element. The package library for the C++ array pointer add function is `#include `.
