Question

Onsider the following two code segments. Code segment ii is a revision of code segment i in which the loop header has been changed.

Code Segment I:


for (int k = 0; k < 10; k++)
// Code block

Code Segment II:


for (int k = 10; k > 0; k--)
// Revised code block

What is the main difference between the two code segments?
a) The loop condition
b) The loop initialization
c) The loop increment
d) The loop termination condition

Answer 1

The main difference between the two code segments is the loop condition. In Code Segment I, the loop condition is k < 10, while in Code Segment II, the loop condition is k > 0. The difference in the loop condition affects the direction of the loop iteration.

Step-by-step explanation:

The main difference between the two code segments is the loop condition. In Code Segment I, the loop condition is k < 10, which means the loop will continue executing as long as the value of k is less than 10. In Code Segment II, the loop condition is k > 0, which means the loop will continue executing as long as the value of k is greater than 0.

So, the difference lies in the direction of the loop iteration. Code Segment I will iterate from 0 to 9, incrementing k by 1 in each iteration. Code Segment II, on the other hand, will iterate from 10 to 1, decrementing k by 1 in each iteration. The loop initialization and increment/decrement are the same in both code segments.
