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