Conditional and Looping Constructs — Question 4

9

In the above code, num1 += num2 + num3 is a shorthand notation for num1 = num1 + num2 + num3.

Given,

num1 = 4
num2 = 3
num3 = 2

First, the expression num2 + num3 is evaluated:

num2 + num3 = 3 + 2 = 5

Now the expression becomes:

num1 = num1 + 5

which translates to:

num1 = 4 + 5 = 9
