Question

Write a function called mathgame.m that repeatedly asks a user to answer a simple addition question. After each question the user is told if their answer is correct or incorrect and they are given the opportunity to continue or to stop. When they stop a summary of their results for the game is provided.

Tackle this problem in small pieces. The following is a suggested strategy but certainly not the only one:

Create two random integers between 1 and 10 and store them in separate variables.

Compute the sum of the two integers and store the result in another variable.

Output the question so the user can see the two random numbers but can not see the result of the sum operation.

Prompt the user to enter their guess and collect it using the input function.

Determine if the user

Explanation / Answer

function mathgame = mathgame()
    disp('Welcome to the math game!');
    count = 1;
    correct = 0;
    incorrect = 0;
    rand1 = 1 + 9 * rand(1);
    rand2 = 1 + 9 * rand(1);
    sprintf("%d: %d + %d =",count,rand1,rand2);
    answer = input('');
    if answer == rand1+rand2
        disp('Correct!');
        correct = correct +1;
    else
        disp('Incorrect!');
        incorrect = incorrect+1;
    end
    again = input('Again','s');
    while strcmp(again,'y')==1
        count = count+1;
        rand1 = 1 + 9 * rand(1);
        rand2 = 1 + 9 * rand(1);
        sprintf("%d: %d + %d =",count,rand1,rand2);
        answer = input('');
        if answer == rand1+rand2
            disp('Correct!');
            correct = correct +1;
        else
            disp('Incorrect!');
            incorrect = incorrect+1;
        end
    again = input('Again','s');
    end
    sprintf('Correct: %d (%.2f %%), Incorrect %d (%.2f %%)',correct,(100.0*correct/count),incorrect,(100.0*incorrect/count))
end
