Question
What needs to go into <condition> for the code to output:12345for(int num = 1; <condition>; num++) { System.out.println(num);}a.)num < 6b.)num > 5c.)num < 5d.)num == 5
Solution
The correct answer is a.) num < 6.
Here's why:
The condition in a for loop determines how long the loop will continue to run. In this case, we want the loop to run while the variable num is less than 6.
Step by step explanation:
- The loop starts with num = 1.
- It checks the condition. If num is less than 6, it enters the loop. If not, it exits the loop.
- It prints the value of num.
- It increments num by 1.
- It goes back to step 2.
This process repeats until num is no longer less than 6. So, the loop will print the numbers 1, 2, 3, 4, and 5, which is the desired output.
The other conditions will not give the desired output:
b.) num > 5: This condition will never be true, so the loop will not run at all. c.) num < 5: This condition will stop the loop before num reaches 5, so it will only print 1, 2, 3, and 4. d.) num == 5: This condition will only be true when num is 5, so it will only print 5.
