Question

Transient Population
Populations are effected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data:
The starting size of a population P
The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B
The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D
The average annual number of people who have arrived A
The average annual number of people who have moved away M
The number of years to display nYears
Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formula
N = P + BP - DP + A - M
where N is the new population size, P is the previous population size, and B, D, A and M are as defined above. The function should return the value computed for N and should receive the values of P, B, D, A and M as parameters.

Prompts And Output Labels. The program first displays the message "This program calculates population change." on a line by itself, followed by these prompts for the inputs described above:

Explanation / Answer

#include using namespace std; double populationSize(double P, double B, double D, double A, double M); int main() { double populationStart; double annualB; double annualD; double peopleA; double peopleM; int nYears; cout
