Program Code – How C++ Is Used in Backend: Backend Development with C++

#include <iostream>
#include <string>
#include <vector>
#include <map>
#include <stdexcept>

// A mock database for simplicity.
std::map<std::string, std::string> mockDatabase{
    {'user:001', 'Alice'},
    {'user:002', 'Bob'},
    {'user:003', 'Charlie'}
};

// Represents a simple user with an ID and a Name.
class User {
    std::string id;
    std::string name;

public:
    User(std::string userId, std::string userName) : id(std::move(userId)), name(std::move(userName)) {}

    std::string getId() const {
        return id;
    }

    std::string getName() const {
        return name;
    }
};

// Simulate a backend service for managing users.
class UserService {
    // Here, we simulate a database call to fetch user data.
    std::string fetchUserNameFromDB(const std::string& userId) {
        if (mockDatabase.find(userId) == mockDatabase.end()) {
            throw std::invalid_argument('User not found.');
        }
        return mockDatabase[userId];
    }

public:
    // Retrieves a User object for a given user ID.
    User getUserById(const std::string& userId) {
        std::string userName = fetchUserNameFromDB(userId);
        return User(userId, userName);
    }
};

// Main function to run the application.
int main() {
    std::cout << 'Backend with C++ demo
';

    UserService userService;

    try {
        // Fetching users by ID.
        User user1 = userService.getUserById('user:001');
        User user2 = userService.getUserById('user:002');

        std::cout << 'Fetched User 1 - ID: ' << user1.getId() << ', Name: ' << user1.getName() << std::endl;
        std::cout << 'Fetched User 2 - ID: ' << user2.getId() << ', Name: ' << user2.getName() << std::endl;

        // Attempting to fetch a user that does not exist will throw an error.
        userService.getUserById('user:010');
    } catch (const std::exception& e) {
        std::cout << 'Error: ' << e.what() << std::endl;
    }

    return 0;
}

Code Output:

Backend with C++ demo
Fetched User 1 - ID: user:001, Name: Alice
Fetched User 2 - ID: user:002, Name: Bob
Error: User not found.

Code Explanation:

The program illustrates a basic backend system written in C++ where users are managed. Here’s the breakdown of how the code works:

1. We first define a mock database using a std::map that maps user IDs to user names. This simulates a real-world database in a simplified manner.

2. A User class is defined that contains a user’s ID and name and methods to retrieve these properties.

3. The UserService class acts as a service layer that interacts with the ‘database’. The fetchUserNameFromDB method is a private method that simulates a database call that retrieves a user’s name given their ID, throwing an error if the user is not found.

4. The getUserById function provides a public interface to get a User object using a given user ID. Internally, it calls fetchUserNameFromDB and constructs a User object with the fetched data.

5. In the main function, we create an instance of UserService and use it to fetch two users by their IDs, which we print to the console. We also demonstrate error handling by trying to fetch a non-existing user, which throws an error that we catch and print an appropriate message.

The architecture of this simple backend system is that main represents the entry point of the application, UserService serves as the business logic layer, and mockDatabase serves as the data layer. This separation of concerns is typical in backend systems, even though this example is highly simplified.
