Print Array Size

An array called nums has already been created for you with the values {10, 20, 30, 40, 50}.

Your task is to calculate and print how many elements are in the array.

In C++, you can find the number of elements in an array using the expression:
sizeof(nums) / sizeof(nums[0])

This works because sizeof(nums) gives the total size of the array in bytes, and sizeof(nums[0]) gives the size of one element. Dividing the two gives you the count of elements.

Expected output:
