Answer to Question #342818 in C++ for herry

Question

Write a user defined function that will ask the user to input 5

array integers and performed the following menu functions:

1. Maximum

2. Minimum

3. Count Odd

4. Count Even

5. Exit

If the user press the following number (s), do the corresponding

functions

1. Print the largest array value

2. Print the lowest array value

3. Count the number of even number(s)

4. Count the number of odd number(s)

5. Exit

Sample Input/Output:

==========Main Menu==========

[1] – Maximum

[2] – Minimum

[3] – CountEven

[4] – CountOdd

[5] – Exit

==============================

Enter your choice: 2

Enter 5 integer number(s):

20

30

8

500

800

The lowest value is: 8
