Explanation
In the above program, we created a module Module1 that contains the Main() function. The Main() function is the entry point for the program.
In the Main() function, we created an array arr1. Then we get the index of the last occurrence of the item within the array using LastIndexOf() method of the Array class. After that, we printed the index of the item on the console screen.
