  🌿  Smart Garden Manager in C++ with Robotics, UI, Drones, and Sound "A Rainwater Conservation System for Tomorrow’s Farms" 🧭  1. Introduction: Farming in the Age of Climate Change In a world where clean water is more precious than gold, efficient  rainwater harvesting and plant care systems  are no longer optional — they’re essential. Smart farming doesn’t mean just automating irrigation. It means combining  robotic drones, environmental sensors, and intelligent scheduling  to build a garden that practically takes care of itself. In this guide, we build a  fully functional Garden Manager System  using  C++  that: Captures and conserves rainwater Uses  robotic drones and sensors  to monitor crop health Integrates a  real-time UI  with progress bars and alerts Includes  timers  for scheduling plant growth and drone tasks Plays  interactive sounds  based on crop state and events Whether you'r...

C++ Mini Projects: Mini Quiz Game


Here is another project on the C++ series. If you have been following along we have built a lot of projects on C++ till here which means you may have a nice practice of hands on C++ and making useful products out of it. So if you have missed the early projects then do check them out. Let's continue the series with this new mini quiz game. 

Description

This game asks multiple choice questions and takes answers as the input. Finally after calculation it displays the results.

Skills used you will learn throughout:

Arrays.....

Are used for storing questions, answer options and the right answers

Loops...

For iterating through all questions

Conditional statements...

For evaluation of answers and calculation of scores.

The code to build the desired project:

#include <iostream>

#include <string>

using namespace std;


int main() {

    // Quiz data

    const int NUM_QUESTIONS = 3; // Number of questions

    string questions[NUM_QUESTIONS] = {

        "What is the capital of France?",

        "Which programming language is known as the 'mother of all languages'?",

        "What is 5 + 3?"

    };

    string options[NUM_QUESTIONS][4] = {

        {"1. Berlin", "2. Madrid", "3. Paris", "4. Rome"},

        {"1. Python", "2. Assembly", "3. C", "4. Java"},

        {"1. 6", "2. 7", "3. 8", "4. 9"}

    };

    int correctAnswers[NUM_QUESTIONS] = {3, 3, 3}; // Correct options

    int userAnswers[NUM_QUESTIONS]; // To store user input

    int score = 0; // User's score


    // Game starts

    cout << "Welcome to the Mini Quiz Game!\n";

    cout << "------------------------------\n";

    cout << "Answer the questions by entering the option number (1-4).\n";


    // Quiz loop

    for (int i = 0; i < NUM_QUESTIONS; ++i) {

        // Display question

        cout << "\nQuestion " << i + 1 << ": " << questions[i] << endl;

        

        // Display options

        for (int j = 0; j < 4; ++j) {

            cout << options[i][j] << endl;

        }

        

        // Take user's answer

        cout << "Your answer: ";

        cin >> userAnswers[i];


        // Validate input

        while (userAnswers[i] < 1 || userAnswers[i] > 4) {

            cout << "Invalid choice. Please select an option between 1 and 4: ";

            cin >> userAnswers[i];

        }


        // Check if the answer is correct

        if (userAnswers[i] == correctAnswers[i]) {

            cout << "Correct!\n";

            ++score; // Increase score

        } else {

            cout << "Wrong. The correct answer was option " << correctAnswers[i] << ".\n";

        }

    }


    // Display final score

    cout << "\nQuiz Over!\n";

    cout << "Your final score: " << score << " out of " << NUM_QUESTIONS << endl;


    return 0;

}

Explanation of code 

Setting up the quiz data...

const int NUM_QUESTIONS = 3;

string questions[NUM_QUESTIONS] = {

    "What is the capital of France?",

    "Which programming language is known as the 'mother of all languages'?",

    "What is 5 + 3?"

};

string options[NUM_QUESTIONS][4] = {

    {"1. Berlin", "2. Madrid", "3. Paris", "4. Rome"},

    {"1. Python", "2. Assembly", "3. C", "4. Java"},

    {"1. 6", "2. 7", "3. 8", "4. 9"}

};

int correctAnswers[NUM_QUESTIONS] = {3, 3, 3};

Questions...

Storing the text for every question:

Options...

Storing four choices for every question 

CorrectAnswers...

Is an array in which every element is corresponding to the right option for every question.


Displaying all questions and the right answer options...

cout << "\nQuestion " << i + 1 << ": " << questions[i] << endl;

for (int j = 0; j < 4; ++j) {

    cout << options[i][j] << endl;

}


Using a nested loop here for every question following its right answer 


Input and its validation 

cin >> userAnswers[i];

while (userAnswers[i] < 1 || userAnswers[i] > 4) {

    cout << "Invalid choice. Please select an option between 1 and 4: ";

    cin >> userAnswers[i];

}

Makes sure that answer of user is between 1 and 4


If user input is not valid the game asks the user to try again 


Checking and the scores...


if (userAnswers[i] == correctAnswers[i]) {

    cout << "Correct!\n";

    ++score;

} else {

    cout << "Wrong. The correct answer was option " << correctAnswers[i] << ".\n";

}


Comparison of users answers to right options

If it finds the answers right , increases the scores

Displaying of final score....


cout << "Your final score: " << score << " out of " << NUM_QUESTIONS << endl;


Total final scores are displayed. 

Now let's go through a full sample of the game.

Sample running of game

....


Example of input and output
