For loops - Assigment

[toldav]

I need help in write this code. If someone can give me a hand on this please.

I need to determine which students have a specific major based upon the button that is clicked , then code will pull all the CS student's name and put them in the results list box. The text box above the results list box should contain the specified major and the text box below the results list box should contain a message indicating the total number of students with specific major.
Please the picture.

Thank you
