How many times is the loop block entered when the following code executes?fоr(int i=16; і < 28; i+=2) { <code inside loop block>}
Question
How many times is the loop block entered when the following code executes?
for(int i=16; i < 28; i+=2) {
<code inside loop block>
}
Solution
The loop starts at 16 and ends before 28, increasing by 2 each time.
Here are the steps:
- i = 16, 16 < 28, so enter the loop. (1st time)
- i = 18, 18 < 28, so enter the loop. (2nd time)
- i = 20, 20 < 28, so enter the loop. (3rd time)
- i = 22, 22 < 28, so enter the loop. (4th time)
- i = 24, 24 < 28, so enter the loop. (5th time)
- i = 26, 26 < 28, so enter the loop. (6th time)
- i = 28, 28 is not less than 28, so the loop ends.
So, the loop block is entered 6 times.
