Birth Rate = No. of Births + Population
Death Rate = No. of Deaths + Population
For example, in a population sample of 200,000 that has 16,000 births and 12,000 deaths per
year, the birth rate and death rate are calculated as follows:
Birth Rate = 16,000 / 200,000 = 0.08
Death Rate = 12,000 / 200,000 = 0.06
Create a class Population that stores the data for the current population, annual no. of
births, and no. of deaths for a period of time. Member functions should return the birth rate and
death rate. Implement the class in a driver program.
f_Name
l_Name
address
city
state
zip
phone
Write the appropriate mutator (set) and accessor (get) functions for these member
variables.
Next, create a class named UnifiUser, which is derived from the class UserProfile.
The UnifiUser class should have the following member variables:
customerID
subscribe
The CustomerNumber variable will be used to hold a unique integer for each customer. The
subscribe variable should be a bool. It will be set to true if the customer wishes to
subscribe the mailing list. Write appropriate mutator (set) and accessor (get) functions
for these member variables. Demonstrate an object of the UnifiUser class in a complete
program.
Note: you may solve this question using abstraction technique or in a single .cpp file.
Question 1:
Suppose the birth rate and death rate in Malaysia are calculated as given below:
Input Validation: Implement appropriate input validations and display error message(s) for
invalid inputs.
Question 2:
Create a class named UserProfile with the following member variables:
Page 2 of 2
Create a class ProjectScore. The constructor of the class should first accept an array of
project scores as its argument. The constructor may initialize or take user input only for 2 or 3
students and suppose the project has 5 modules to enter the score. The class should have a
member function to calculate the average project score for each student. The range of score is
from 1 – 100, and the program should throw an exception in case of invalid score. Write a
driver program to test the functionality.
Write a template for the function named accumulator. The function should receive only
one argument which will determine the no. of values to be read (may be 4 or 5). It should then
accumulate (add) the values entered by the user, and then return the sum of values in the main
function. Test the template in a driver program by sending various types of arguments such as
int, float, double etc., and display the results.
