Question

consider the following iteration statement: int num = 13; int lev = 35; while (lev >= 0) { num -= 3; lev -= 5; } what is the value of num after the for loop terminates? num = -13 num = 5 num = 13

Explanation:

Step1: Analyze loop condition

The while loop runs as long as lev >= 0. Initially, lev = 35.

Step2: Analyze operations in loop

In each iteration, num is multiplied by - 1 and lev is decremented by 5.
Since lev = 35, the number of iterations is $\frac{35}{5}=7$.

Step3: Determine final value of num

Starting with num = 13, multiplying by - 1 an odd number of times (7 times here) will result in num=-13.

Answer:

num = - 13
