Write a c++ program that declares a structure to store country name and population in millions. It declares two structure variables and inputs values (in main). it passes both variables to a function that shows the record of the country with more population.
Kindly answer asap, cuz the due date of assignment is today.
Sure! Here's a step-by-step guide on how you can write a C++ program that accomplishes the task you described.
Step 1: Include the necessary header files.
```c++
#include <iostream>
#include <string>
```
Step 2: Define the structure to store country name and population.
```c++
struct Country {
std::string name;
int population;
};
```
Step 3: Declare a function to compare the population of two countries and show the record of the country with more population.
```c++
void showCountryRecord(const Country& country1, const Country& country2) {
if (country1.population > country2.population) {
std::cout << "Country " << country1.name << " has a larger population of " << country1.population << " million." << std::endl;
} else if (country2.population > country1.population) {
std::cout << "Country " << country2.name << " has a larger population of " << country2.population << " million." << std::endl;
} else {
std::cout << "Both countries have the same population of " << country1.population << " million." << std::endl;
}
}
```
Step 4: Create the main program.
```c++
int main() {
// Declare two structure variables
Country country1, country2;
// Input values for country1
std::cout << "Enter country 1 name: ";
std::getline(std::cin, country1.name);
std::cout << "Enter population of " << country1.name << " (in millions): ";
std::cin >> country1.population;
// Ignore the newline character left in the input buffer
std::cin.ignore();
// Input values for country2
std::cout << "Enter country 2 name: ";
std::getline(std::cin, country2.name);
std::cout << "Enter population of " << country2.name << " (in millions): ";
std::cin >> country2.population;
// Call the function to show the record
showCountryRecord(country1, country2);
return 0;
}
```
That's it! With these steps, you have a complete C++ program that declares a structure to store country names and populations, inputs values for two countries, and passes them to a function to compare and show the record of the country with a larger population.
Make sure to save the file with a `.cpp` extension, compile it, and run it to test your program. Let me know if you need any further assistance!
Sure! I can help you with that. Here's a C++ program that accomplishes what you described:
```cpp
#include<iostream>
using namespace std;
// Declare a structure to store country name and population in millions
struct Country {
string name;
int population;
};
// Function to display the record of the country with more population
void showCountryWithMorePopulation(Country country1, Country country2) {
if (country1.population > country2.population) {
cout << "Country with more population: " << country1.name << endl;
cout << "Population: " << country1.population << " million" << endl;
}
else if (country2.population > country1.population) {
cout << "Country with more population: " << country2.name << endl;
cout << "Population: " << country2.population << " million" << endl;
}
else {
cout << "Both countries have the same population." << endl;
}
}
int main() {
Country country1, country2;
// Input values for the first country
cout << "Enter name of the first country: ";
getline(cin, country1.name);
cout << "Enter population of the first country (in million): ";
cin >> country1.population;
cin.ignore();
// Input values for the second country
cout << "Enter name of the second country: ";
getline(cin, country2.name);
cout << "Enter population of the second country (in million): ";
cin >> country2.population;
cin.ignore();
// Call the function to show the record of the country with more population
showCountryWithMorePopulation(country1, country2);
return 0;
}
```
To compile and run the code, follow these steps:
1. Save the code in a file named "country.cpp".
2. Open a terminal or command prompt, and navigate to the directory where the file is saved.
3. Compile the code using a C++ compiler such as g++:
`g++ country.cpp -o country`
4. Run the program:
`./country`
You will then be prompted to enter the details of two countries. After entering the information, the program will display the country with more population (if there is one).
I hope this helps! Let me know if you have any other questions.
