Problem Statement

Write a program to find the grace marks for a student using switch. The user should enter the class obtained by the student and the number of subjects he has failed in. Use the following logic. - If the student gets first class and he fails in more than 3 subjects, he does not get any grace, Otherwise, he gets a grace of 5 marks per subject. - If the student gets second class and he fails in more than 2 subjects, he does not get any grace. Otherwise, he gets a grace of 4 marks per subject. - If the student gets third class and he fails in more than 1 subject, then he does not get any grace. Otherwise, he gets a grace of 5 marks.
