CENG 198 Spring 2014-15 CENG 198 LABWORK 8 1. Write a method that decides whether two given numbers are amicable numbers or not. Hint: Amicable numbers are two numbers so related that the sum of the proper divisors of the one is equal to the other, one being considered as a proper divisor but not the number itself. Such a pair is (220,284); for the proper divisors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55 and 110, of which the sum is 284; and the proper divisors of 284 are 1, 2, 4, 71, and 142, of which the sum is 220. 2. Assume user enters a series of characters and wants to know how many vowels exist in it. Let’s assume the number of characters in the series entered by the users is 20. Write a program using a while loop to read the characters and count how many characters of each vowel occurs in it. For example, if the series is ‘ABNAVOIEIKONVKAPLBO’ then your program should print: ‘A’ repeated 2 time(s) ‘E’ repeated 1 time(s) ‘I’ repeated 2 time(s) ‘O’ repeated 3 time(s) ‘U’ repeated 0 time(s) Use switch-case statement to count the vowels. Assume all characters are capital characters. CENG 198 Spring 2014-15 3. Assume that you are working for a kinder garden. The meal menu is defined according youngest child.

Write a program that input n and n personal information of employees. Each employee information contains gender code (F for females, M for males) and age. Program will find and display: a. Number of female workers older than 30 and number of male workers younger than 50 b. Average age of female and male workers Sample Run: Enter number of employees: 100 Enter gender and age: F 39 Enter gender and age: F 33 Enter gender and age: M 45 Enter gender and age: F 45 Number of female workers older than 30: 45 Number of male workers younger than 50: 33 Average age of females: 35.7 Average age of males: 47.8
