Question

- This program should get input from user to select the case. Create two cases.                 

- If user selects first case, then program should do the following:                 

o Program asks user to enter any number, multiply every element of the array z by that number, and print the                    results.                 

o If user selects second case, then the program should print all the elements in array z which are either                    divisible by 2 or 5.{ Hint: you can use logical OR operator for a test condition. }                 

- Include the default case in your program that prints a message
