My program exited without running with return value 3221225620

I'm trying to write a c++ code that calculates a student's percentage grade. This is a sample of what the output should look like

Enter student's first and last name: John Smith Number of questions on the test: 40 Number of answers the student got correct: 31 John Smith 77.5%

Below is my own code. It allows me to enter the first line Enter student's first and last name: but then it just exits and this is the feedback return value 3221225620. please what am I doing wrong?

        // Lab 3 percentage.cpp
        // This program will determine the percentage
        // of answers a student got correct on a test.


        #include<iostream>
        #include<string>

        using namespace std;``

        int main()
        {
        string name;
        int numQuestions,
            numCorrect,
            studentName;
        double percentage;
        

        // Get student's test data
        cout << "Enter student's first and last name: ";
        cin >> studentName;

        cout << "Number of questions on the test: ";
        cin >> numQuestions;

        cout << "Number of answers the student got correct: ";
        cin >> numCorrect;

        // Compute and display the student's % correct
        percentage = (numCorrect / numQuestions) * 100;
        // WRITE A STATEMENT TO COMPUTE THE % AND ASSIGN THE RESULT TO percentage.

        cout << "The student: " << studentName << "has a test score of " << percentage << endl;

        return 0;
        }
