Write a program that uses a function to reverse a list of integers. The function is to receive a pointer to the first item along with the number of items and use pointer arithmetic to access the items. Arrays are NOT permitted in the function.

In the main program

declare a large array of 100 integers.

Request the user to enter numbers and insert them into the array in order.

The user can enter anywhere from 3 to 100 numbers.

You cannot use array notation to insert the number into the "array"

You must use pointer arithmetic

Call the reverse function with the address of the first element (i.e., a pointer) and the number of items the user entered.

The only declaration permitted in the function is a temporary that is declared as a POINTER to an integer

The function will reverse the items

You cannot use array notation to swap numbers

You must use pointer arithmetic

The main program is to print the reversed numbers using pointer arithmetic to access them.

Please explain this code. Also what is missing?

\} void swap (int \&a, int &b) int temp; temp =a; a=b; b=temp
