Quiz model

Design the skeleton of Question and Quiz structs.

Project: Quiz app

In this five-lesson project you'll build a quiz app. Each lesson adds a piece; by the final lesson you'll have a program that combines all parts.

Throughout the project you'll define a struct Question type, add questions, run the quiz, and compute score and percentage. The functions you'll define: add_question, run_quiz, print_percentage and run_quiz_app. In this first lesson you'll design the model: the struct Question definition and the main skeleton.

Question struct

struct Question models a question. It has two core fields: text holds the question text, correct holds the index of the correct answer.

Example: struct Question { char text[64]; int correct; };. Here text is a 64-byte string, correct is an integer 0-3. This design represents multiple-choice questions simply; options are kept separate. You'll use this struct throughout the project; in the next lessons you'll add and play questions.

Exercise Write the quiz skeleton

Define struct Question with char text[64]; and int correct;. Write int main(void) and inside it print "Quiz hazır" with printf("Quiz hazır\n");.

Show example solution

#include <stdio.h>

struct Question {
    char text[64];
    int correct;
};

int main(void) {
    printf("Quiz hazır\n");
    return 0;
}

Test yourself

What does struct Question store?
- Only the question text
- Only the answer
- The question count
- Question text and correct answer
Show answer

Question text and correct answer — struct Question stores both the question text and the correct answer.
Match fields to purpose

Correct answer
struct Question

Question type

Text field

Complete the Question text field

struct Question { char ____[64]; int correct; };

Show answer

struct Question { char text[64]; int correct; };
