c++ get last element in array

To get the last element in a C++ array, you can use the index of the last element, which is the size of the array minus one. Here are the steps to do it:

1. Declare an array with the desired elements. For example, int arr[] = {1, 2, 3, 4, 5};.

2. Find the size of the array using the sizeof operator divided by the size of one element. For example, int size = sizeof(arr) / sizeof(arr[0]);.

3. Subtract one from the size to get the index of the last element. For example, int lastIndex = size - 1;.

4. Access the last element using the index obtained in the previous step. For example, int lastElement = arr[lastIndex];.

By following these steps, you can retrieve the last element of a C++ array.
