The class should have one get_data method to read the values of the class variables. Then write an application driver class that reads the data of three Canadian provinces and prints:

A. The name of the province whose premier`s name is on top of the list of all premiers name in asending alphabetical order.

B. The name of the province, that has the largest population.

Explanation / Answer

#include <iostream>

using namespace std;

class Province{
private:
string name;
string premier;
int population;
int cities;
public:
void get_data();//get data from input
string get_name(){
return name;
}
string get_premier(){
return premier;
}
int get_population(){
return population;
}
int get_cities(){
return cities;
}
int operator != (const Province &b){//Assuming province names are unique
return name != b.name;
}
};

void Province::get_data() {
cout<<"Enter Province name: ";
getline(cin,name);
cout<<"Enter Premier name: ";
getline(cin,premier);
cout<<"Enter the population of the province: ";
cin>>population;
cout<<"Enter number of cities in the province: ";
cin>>cities;
cin.get();
}

Province max_premier(Province arr[],size_t size){//size_t is a standard unsigned integer used for size info
int max=0;
for (size_t i = 0; i < size; i++) {
if( arr[i].get_premier() > arr[max].get_premier()){
max = i;
}
}
return arr[max];
}

Province* twolowest_cities(Province arr[],size_t size){//size_t is a standard unsigned integer used for size info
int min=0;
Province *res = new Province[2];
for (size_t i = 0; i < size; i++) {
if( arr[i].get_cities()<arr[min].get_cities()){
min = i;
}
}
res[0] = arr[min];
min = (min+1)%size;//take another element as candidate second min
for (size_t i = 0; i < size; i++) {
if( arr[i].get_cities()<arr[min].get_cities() && arr[i]!=res[0]){
min = i;
}
}
res[1] = arr[min];
return res;
}

Province max_population(Province arr[],size_t size){//size_t is a standard unsigned integer used for size info
int max=0;
for (size_t i = 0; i < size; i++) {
if( arr[i].get_population() > arr[max].get_population()){
max = i;
}
}
return arr[max];
}

int main(int argc, char const *argv[]) {
Province arr[3];
Province cur;
Province *low;
for (size_t i = 0; i < 3; i++) {
arr[i].get_data();
}
cur = max_premier(arr,3);
cout<<"Name of provice at top according to order of premiers: "<<cur.get_name()<<' ';
cur = max_population(arr,3);
cout << "Name of province with max population: "<< cur.get_name() << ' ';
low = twolowest_cities(arr,3);
cout << "Two provinces with least number of cities:" << ' ';
for (size_t i = 0; i < 2; i++) {
cout << low[i].get_name() << ' ';
}
return 0;
}
