Question

Write a program which asks the student to choose between the summation exam and subtraction exam. In the summation or subtraction exam the student will be asked ten times to sum or subtract two single digit random integer numbers Check his answers, If the student answers 80% or more of the questions correctly he will pass otherwise he will be asked if he would like to get the exam again, If his answer is ok repeat the exam for him. If the student failed to success two times do not ask him to repeat the exam and till him that he should study well before getting the exam again. Note: If the student answers the first five simultaneous questions correctly give him 100% score and terminate the exam. matlab

Answer 1

The program will guide the student through the summation and subtraction exams, and provide feedback based on their performance.

function runMathExam()

passThreshold = 0.8;

maxAttempts = 2;

fprintf('Welcome to the Math Exam!\\');

while true

fprintf('Choose the type of exam:\\');

fprintf('1. Summation Exam\\');

fprintf('2. Subtraction Exam\\');

choice = input('Enter your choice (1 or 2): ');

if choice == 1

operator = '+';

elseif choice == 2

operator = '-';

else

fprintf('Invalid choice. Please enter 1 or 2.\\');

continue;

end

correctAnswers = 0;

attempts = 0;

while attempts < maxAttempts

for i = 1:10

num1 = randi(9);

num2 = randi(9);

if i <= 5

correctAnswer = num1 + num2;

else

correctAnswer = num1 - num2;

end

userAnswer = input(sprintf('%d. %d %s %d = ', i, num1, operator, num2));

if userAnswer == correctAnswer

fprintf('Correct!\\');

correctAnswers = correctAnswers + 1;

else

fprintf('Incorrect. The correct answer is %d.\\', correctAnswer);

end
