C++ PROGRAM

Exercise 1: Average Age of Adults Write a program that computes the average age of adults in a sample population. The program prompts the user to enter the size of the population and then using a for loop, it shall prompt the user for the age of every person in the population. The program shall compute the average age of adults only. Produce output as shown in the sample input/output. Note: an adult is a person whose age is 2 18. Sample input/output: Enter size of population sample : 6 Enter age of person # 1:20 Enter age of person # 2: 10 Enter age of person #3: 15 Enter age of person # 4: 24 Enter age of person #5: 19 Enter age of person #6: 18 There are 4 adults in the population sample. The average age of adults is: 20.25 Exercise 2: Count the Numbers Write a program that prompts the user to enter a number n. Then, it asks the user to enter a sequence of numbers ending with -999. The program then displays the count of numbers in the sequence smaller than n, the count of numbers larger than n, and the count of numbers equal to n. Sample input/output: Enter the value of n: 56 Enter a number, -999 to stop: 67 Enter a number, -999 to stop: 23 Enter a number, -999 to stop: 19 Enter a number, -999 to stop: 88 Enter a number, -999 to stop: 56 Enter a number, -999 to stop: 12 Enter a number, -999 to stop: 85 Enter a number, -999 to stop: 55 Enter a number, -999 to stop: -999 There are 4 numbers less than 56 There are 3 numbers grater than 56 There are 1 numbers equal to 56
