here hope this helps.
Explanation:
#include <iostream>
using namespace std;
//Country class declaration
class Country {
public:
string country;
double population;
double area;
};
int main()
{
Country ctry[100];
int n;
double large_population, large_area, large_density, temp_density;
string p_ctry, a_ctry, d_ctry;
// Reading input on how many countries we want to store the information
cout << "How many countries you want to read the data ? ";
cin >> n;
// Reading country name, population and area for the countries
for(int i = 0; i < n; i++) {
cout << "Enter Country Name: ";
cin >> ctry[i].country;
cout << "Enter population: ";
cin >> ctry[i].population;
cout << "Enter area: ";
cin >> ctry[i].area;
}
large_population = 0;
large_area = 0;
large_density = 0;
// Identifying largest population and area country
for(int i = 0; i < n; i++) {
if(ctry[i].population > large_population) {
p_ctry = ctry[i].country;
large_population = ctry[i].population;
}
if(ctry[i].area > large_area) {
a_ctry = ctry[i].country;
large_area = ctry[i].area;
}
// Population density is population divided by total land area or water volume
temp_density = ctry[i].population / ctry[i].area;
if(temp_density > large_density) {
d_ctry = ctry[i].country;
large_density = temp_density;
}
}
cout << endl;
cout << "Country "<< a_ctry << " has the largest area " << large_area << endl;
cout << "Country "<< p_ctry << " has the largest population " << large_population << endl;
cout << "Country "<< d_ctry << " has the largest population density " << large_density << endl;
return 0;
}
