Write one dimensional array C++ program that ask to the user to enter the array size and reads n integers, finds the largest of them, and count its occurrences. Suppose that you entered 100, 200, 100, 50, 50, 50 as shown in sample input/output. The program finds that the largest is 200 and that the occurrence count for 200 is 1.
