Write a program in C++that allows students to answer multiple-choice and fill in the blank questions in the console window, and ultimately display their scores

Sure, here's an example program in C++ that allows students to answer multiple-choice and fill in the blank questions in the console window, and ultimately display their scores:

#include <iostream>
#include <string>

using namespace std;

int main() {
    // declare variables for questions and answers
    string q1 = "What is the capital of France?\n";
    string q2 = "What is the largest planet in our solar system?\n";
    string q3 = "What is the formula for water?\n";
    string a1 = "Paris";
    string a2 = "Jupiter";
    string a3 = "H2O";
    
    // declare variables for student answers and score
    string ans1, ans2, ans3;
    int score = 0;
    
    // ask first question and get answer
    cout << q1;
    cin >> ans1;
    if (ans1 == a1) {
        cout << "Correct!" << endl;
        score++;
    } else {
        cout << "Incorrect. The correct answer is " << a1 << "." << endl;
    }
    
    // ask second question and get answer
    cout << q2;
    cin >> ans2;
    if (ans2 == a2) {
        cout << "Correct!" << endl;
        score++;
    } else {
        cout << "Incorrect. The correct answer is " << a2 << "." << endl;
    }
    
    // ask third question and get answer
    cout << q3;
    cin >> ans3;
    if (ans3 == a3) {
        cout << "Correct!" << endl;
        score++;
    } else {
        cout << "Incorrect. The correct answer is " << a3 << "." << endl;
    }
    
    // display final score
    cout << "Your final score is " << score << "/3." << endl;
    
    return 0;
}

In this program, we first declare strings for the questions and their corresponding answers. Then we declare variables for the student's answers and their score. We ask each question with `cout` and get the student's answer with `cin`. If the answer is correct, we increment the score by 1 and output "Correct!" with `cout`. If the answer is incorrect, we output the correct answer with `cout`. Finally, we display the student's final score with `cout`.
