Question

Write a C++ program to grade the answers to a true-false quiz given to students in a course. The quiz consists of 5 true-false questions. Each correct answer is worth 2 points.

Answer 1

The quiz program is an illustration of loops and conditional statements

• Loops are used to perform repetition
• Conditional statements are used to make decisions

The quiz program

The quiz program written in C++, where comments are used to explain each action is as follows:

#include <iostream>

using namespace std;

int main(){

   //This prints the instruction

   cout<<"Enter T/t for True; F/f for False\n";

   //This initializes the question

   string questions[5] = { "Q1", "Q2", "Q3", "Q4", "Q5"};

   //This initializes the correct options

   char options[5] = { 'T','T','F','F','T'};

   //This declares the user response

   char opt;

   //This initializes the score to 0

   int score = 0;

   //This loop is repeated 5 times

   for (int i = 0; i < 5; i++){

       //This prints the current question

       cout << i + 1 <<". "<<questions[i]<<"\nAnswer: ";

       //This gets the user response

       cin>>opt;

       //If the user response is correct

       if(toupper(opt) == options[i]){

           //The score is incremented by 2

           score+=2;

       }

   }

   //This prints the total score

   cout<<"Score: "<<score;

   return 0;

}
