# Estimated Population Formula at End of the Year

If P is the population on the first day of the year, B is the birth rate, and D is the death rate, the estimated population at the end of the year is given by the formula:

P + (B * P)/100 - (D * P)/100

The population growth rate is given by the formula:

B - D

Write a program that prompts the user to enter the starting population, birth and death rates, and n, the number f years. The program should then calculate and print the estimated population after n years. Your program must consist of the following functions:

a. growthRate: This function takes as its parameters the birth and death rate, and it returns the population growth rate.

b. estimatedPopuation: This function takes as its parameters the current population, population growth rate, and n, the number of years. It returns the estimated population after n years.

Your program should to accept a negative birth rate, negative death rate, or a population less than 2.

Format it in cpp.

#### Solution Summary

This solution provides guidelines on creating a program in cpp format to find the growth rate and the estimated population.
