Can anyone solve this

Question

A teacher gives a 20-question true/false test to his students. To calculate their grade, he gives 2 points for a correct answer, -1 point for an incorrect answer, and does nothing if they leave it blank. You are going to write a program that outputs to the screen each student’s ID, their answers, the number of points they received on the test, and their letter grade
