How to Create Quiz Game in C

Introduction

Creating a quiz game in C programming is a great way to practice coding and improve your programming skills. This project is simple enough for beginners but also challenging enough to teach important concepts like loops, conditionals, and functions. In this guide, you will learn how to create a basic quiz game in C, step by step. By the end, you will have a fully functional quiz game that you can compile and run on your computer.

Setting Up Your Development Environment

Before you start coding, make sure you have a C compiler installed on your computer. You can use GCC, which is available on most platforms, or an IDE like Code::Blocks or Dev-C++. Once your environment is set up, create a new C file where you will write your quiz game code.

Step-by-Step Instructions

Step 1: Adding a Menu to the Game

First, you need to create a simple menu that will be displayed when the program starts. This menu will allow the user to choose between starting the quiz, viewing instructions, or exiting the game.

#include <stdio.h>
#include <string.h>

struct Question {
    char question[100];
    char answer[50];
};

void showMenu();
void startQuiz();
void showInstructions();

int main() {
    int choice;

    do {
        showMenu();
        printf("Enter your choice: ");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                startQuiz();
                break;
            case 2:
                showInstructions();
                break;
            case 3:
                printf("Exiting the game. Goodbye!\n");
                break;
            default:
                printf("Invalid choice. Please try again.\n");
        }
    } while (choice != 3);

    return 0;
}

Step 2: Creating the Menu Function

The showMenu() function will display the main menu options. This function will be called every time the user finishes a round or when the program starts.

void showMenu() {
    printf("\n*********************************\n");
    printf("*          QUIZ GAME            *\n");
    printf("*********************************\n");
    printf("1. Start Quiz\n");
    printf("2. Instructions\n");
    printf("3. Exit\n");
    printf("*********************************\n");
}

Step 3: Implementing the Start Quiz Function

The startQuiz() function will handle the quiz questions, scoring, and feedback, similar to what was explained earlier.

void startQuiz() {
    struct Question quiz[3] = {
        {"What is the capital of France?", "Paris"},
        {"What is 5 + 7?", "12"},
        {"Who wrote 'Hamlet'?", "Shakespeare"}
    };

    int score = 0;
    char userAnswer[50];

    for (int i = 0; i < 3; i++) {
        printf("%s\n", quiz[i].question);
        scanf("%s", userAnswer);

        if (strcmp(userAnswer, quiz[i].answer) == 0) {
            printf("Correct!\n");
            score++;
        } else {
            printf("Wrong! The correct answer is %s.\n", quiz[i].answer);
        }
    }

    printf("\nYou got %d out of 3 questions correct.\n", score);

    if (score == 3) {
        printf("Excellent! You know your stuff.\n");
    } else if (score == 2) {
        printf("Good job! But there's room for improvement.\n");
    } else {
        printf("Better luck next time!\n");
    }
}

Step 4: Writing the Instructions Function

The showInstructions() function provides simple instructions on how to play the quiz game. This can be helpful for users who are new to the game.

void showInstructions() {
    printf("\n*******************************\n");
    printf("*       INSTRUCTIONS           *\n");
    printf("*******************************\n");
    printf("1. You will be asked 3 questions.\n");
    printf("2. Type your answer and press Enter.\n");
    printf("3. Your score will be displayed at the end.\n");
    printf("4. To exit the quiz, choose option 3 from the menu.\n");
    printf("*******************************\n");
}

Step 5: Adding Additional Features (Optional)

To make your quiz game more interesting, you can add features like:

• Multiple-choice questions: Instead of letting the user type the answer, give them multiple choices to select from.
• Time limit: Add a timer to each question to increase the difficulty.
• Randomized questions: Shuffle the questions to make each playthrough unique.

Compiling and Running the Program with the Menu

After adding the menu, compile and run the program using the same steps as before:

1. Compile the Code:
   • If you are using GCC, open your terminal or command prompt and navigate to the directory where your C file is located:
   • Run the following command:

     gcc -o quizgame quizgame.c

   • This will create an executable file named quizgame.
2. Run the Program:
   • After compiling, run the program by typing:

     quizgame

   • If you are using an IDE, simply press the "Run" button.
3. Use the Menu:
   • The program will now display the main menu. Choose an option to start the quiz, view instructions, or exit the game.

Conclusion

Creating a quiz game in C programming is a fun and educational project. It helps you practice basic programming concepts while building something that you can actually use. By following this guide, you now have a working quiz game that you can further enhance with additional features. Keep experimenting and improving your skills.
