Array wont compile correctly

[V416]

I am quite new to C++ and I can't seem to see the problem with my code. I have been working on in this assignment for about 3 days now. Any help will be greatly appreciated.
Here are some output examples.
/*
Enter the size of the array: 5
Enter the numbers in the array, separated by a space, and press enter: 1 5 9 7 3
Enter a number to search for in the array: 9
Found value 9 at index 2 which took 3 checks.

Enter the size of the array: -5
ERROR: you entered an incorrect value for the array size!

Enter the size of the array: 5

Found value 9 at index 0 which took 1 checks.
We ran into the best case scenario!
