如何从指向指针数组的指针中删除对象？

#include <iostream>

void deleteObjectFromPointerArray(int** pointerArray, int arraySize, int* targetObject) {
    int targetIndex = -1;

    // Find the target object in the pointer array
    for (int i = 0; i < arraySize; i++) {
        if (pointerArray[i] == targetObject) {
            targetIndex = i;
            break;
        }
    }

    if (targetIndex != -1) {
        // Shift the pointers after the target object by one position
        for (int i = targetIndex; i < arraySize - 1; i++) {
            pointerArray[i] = pointerArray[i + 1];
        }

        // Decrease the size of the pointer array
        arraySize--;

        // Delete the target object
        delete targetObject;
    }
}

int main() {
    const int arraySize = 5;
    int* pointerArray[arraySize];

    // Initialize the pointer array with some objects
    for (int i = 0; i < arraySize; i++) {
        pointerArray[i] = new int(i);
    }

    // Delete an object from the pointer array
    int* targetObject = pointerArray[2];
    deleteObjectFromPointerArray(pointerArray, arraySize, targetObject);

    // Print the updated pointer array
    for (int i = 0; i < arraySize - 1; i++) {
        std::cout << *pointerArray[i] << " ";
    }
    std::cout << std::endl;

    return 0;
}
