Write a program which 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 the number of subjects he failed in is greater than 3, then he does not get any grace. Otherwise the grace is of 5 marks per subject.
- If the student gets second class and the number of subjects he failed in is greater than 2, then he does not get any grace. Otherwise the grace is of 4 marks per subject.
- If the student gets third class and the number of subjects he failed in is greater than 1, then he does not get any grace. Otherwise the grace is of 5 marks.
# Determine the grace marks obtained by student
c = int(input('Enter the class: '))
sub = int(input('Enter the number of subjects failed: '))
while c :
if c == 1 :
if sub <= 3 :
print('Student gets total of', 5 * sub, 'grace marks')
else :
print('No grace marks')
break
if c == 2 :
if sub <= 2 :
print('Student gets total of', 4 * sub, 'grace marks')
else :
print('No grace marks')
break
if c == 3 :
if sub == 1 :
print('Student gets 5 grace marks')
else :
print('No grace marks')
