Explanation / Answer

//Pseduco code explanation :

//Button source event

If the source of the event was the Search button

Then lastName = retrieve the text from the mSearchText text field.

If lastNam is the empty string

Then Call messageBox()

Display"Please enter the student's last name."

Else

student = Call mMain.search(lastName)

Then Call clear()

Else if the source of the event was the

Exit button

Then If mStudent is not null

Then Call saveStudent(mStudent)

Call mMain.exit() to terminate the application End If
