Question

I’m trying to compare and multiply 2 random number variables with the int value entered in textboxes. If it is the correct increment the correct answers it does not increase the number although it increment works alone but it does not work with the textbox.

private void button1_Click(object sender, EventArgs e)
{
    int x = Randomnumber.Next(12);
    int z = Randomnumber.Next(12);

    //int cv = +correct;
    textBox2.Text = x.ToString();
    textBox3.Text = z.ToString();

    int s = x * z;
    if (s == int.Parse(textBox4.Text))
    {
        correct++;
        numbercorrect.Text = correct.ToString();
    }
}

Answer 1

    private void button1_Click(object sender, EventArgs e)
    {


        int result = Convert.ToInt32(textBox4.Text); int x, z;

        if (Convert.ToInt32(textBox2.Text) * Convert.ToInt32(textBox3.Text) == result)
        {
            correct++;
            numbercorrect.Text = correct.ToString();
            Randomnumber.Next(12);
            textBox2.Text = Randomnumber.Next(12).ToString();
            textBox3.Text = Randomnumber.Next(12).ToString();

        }

}
