Explanation / Answer

Question 5
A) first>second = true
first>third = false

hence control goes to second>third which is also false
finally else condition executes and prints :

" 8 is the largest "

Question 5
B)

Atleast one comparision is made if the values are like
first =8 second =7 third =6

then the first if condition is true and prints "8 is largest"

Question 5
C)

Atmost two comparisions are made as in solution for (A) bit.
values : first = 8 second = 7 third = 8

Question 5
D)

Suppose if you take solution for (A) bit , then both first and third are largest numbers having value 8 but the code gives only third as largest.
