Calculate Grade

Scroll bars select midterm and final exam, average is calculated

To calculate the grade from the midterm and final exams we must divide (midterm+final) by 2. If we use midterm+final/2, it will find the midterm plus half of the final.explanation

Build the form as shown below:

Horizonal Scroll Bars

  Name:  hsbMidterm
  LargeChange = 1
  
  Name:  hsbFinal
  LargeChange = 1

Labels

  Name:  lblInstructions
  Text = "Select midterm and final grade:"
  
  Name:  lblMidterm
  Text = "Midterm: 0"
  
  Name:  lblFinal
  Text = "Final: 0"

  Name:  lblAverage
  Text = "Average: 0"

Write the code as shown below:

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void hsbMidterm_Scroll(object sender, ScrollEventArgs e)
        {
            //calculate grade
            int midterm = hsbMidterm.Value;
            int final = hsbFinal.Value;
            double average = (midterm + final) / 2;
            lblMidterm.Text = "Midterm: " + midterm;
            lblFinal.Text = "Final: " + final;
            lblAverage.Text = "Average: " + average;
        }

        private void hsbFinal_Scroll(object sender, ScrollEventArgs e)
        {
            //calculate grade
            int midterm = hsbMidterm.Value;
            int final = hsbFinal.Value;
            double average = (midterm + final) / 2;
            lblMidterm.Text = "Midterm: " + midterm;
            lblFinal.Text = "Final: " + final;
            lblAverage.Text = "Average: " + average;
        }
        
    }
}

Remember, you should try doing each of these programs on your own. Get it to work, break it, modify it, and then try to write it on your own!
