Question

consider the following: int a = 7; int b = 3; system.out.println(3 + a % 2); b += 5 - a; system.out.println(b); what is the output of this program? 49 41 01

Explanation:

Step1: Calculate the first print statement

First, calculate \(a\%2\) where \(a = 7\). The modulo operation \(7\%2\) gives the remainder when \(7\) is divided by \(2\). \(7\div2 = 3\) with a remainder of \(1\), so \(7\%2=1\). Then \(3 + a\%2=3 + 1=4\). But this is just the first print statement's value.

Step2: Calculate the new value of \(b\)

The statement \(b +=5 - a\) is equivalent to \(b=b+(5 - a)\). Given \(a = 7\) and \(b = 3\), then \(5 - a=5 - 7=- 2\). So \(b=3+( - 2)=1\).
