Write a program that predicts the approximate size of a population of organisms.

Question

Write a program that predicts the approximate size of a population of organisms. The application should use text boxes to allow the user center the starting number of organisms, the average daily population increase (as percentage), and the number of days the organisms will be left to multiply. For examle, assume the user enters the following values:

WRITE THE PROGRAM IN PYTHON ONLY

starting number of organisms: 2

Average daily increase : 30%

Number of days to multiply: 10

The program should display the following the following table table of data

Day Approximate Population

1 2

2 2.6

3 3.38

4 4.394

5 5.7122

6 7.42586

7 9.653619

8 12.5497

9 16.31462

10 21.209

Explanation / Answer

// C++ code
#include <iostream>
#include <fstream>
#include <cctype>
#include <cstring>
#include <stdlib.h> /* srand, rand */
#include <iomanip>
#include <limits.h>
#include <cmath>
#include <algorithm>
#include <vector>

using namespace std;

int main()
{
int start, days;
double average;
double sum = 0;

cout << "Starting number of organisms: ";
cin >> start;

cout << "Average daily increase: ";
cin >> average;

cout << "Number of days to multiply: ";
cin >> days;

sum = start;
cout << " Day Approximate Population ";

for (int i = 1; i <= days; ++i)
{
cout << i << " " << sum << endl;
sum = sum + sum*average/100;
  
}
  

return 0;

}

/*
output:

Starting number of organisms: 2
Average daily increase: 30
Number of days to multiply: 10

Day Approximate Population
1 2
2 2.6
3 3.38
4 4.394
5 5.7122
6 7.42586
7 9.65362
