Question

One problem in timber management is to determine how much of an area to leave uncut so that the harvested area is reforested in a certain period of time. It is assumed that reforestation takes place at a known rate per year, depending on climate and soil conditions. A reforestation equation expresses this growth as a function of the amount of timber standing and the reforestation rate. For example, if 100 m2 are left standing after harvesting and the reforestation rate is 0.05, then 100 + (0.05 * 100),or 105 m2, are forested at the end of the first year. At the end of the second year, the number of m2 forested is 105 + (0.05 * 105), or 110.25 m2. Assume that the area we are talking about has a total of 10,000 m2, with 5000 m2 uncut and a reforestation rate of 0.04. Write a program to print a table showing the number of m2 forested at the end of each year, for a total of 20 years. [10 Marks]

Answer 1

SOLUTION:-

#include <iostream>
#include <stdlib.h>
#include <math.h>
using namespace std;

int main()
{
int year=1 ;

double Acres = 10000, uncut = 5000, Reforest_rate = .04;

double reforest = 0;

while(year<=20)

{

uncut = uncut + (uncut*Reforest_rate); // Calculation of Reforestation Growth

cout << "In Year:"<<year <<","<<"The Forested Area is:"<<"\t"<< uncut<<"m2"<< endl;

year++;

}

return 0;
}
