Question
What would be output at the end of the following code segment? int num = 0; for(int row = 0; row < 8; row++ ) { for(int col = 0; col < 0; col++) { num++; } } System.out.println(num);error180
Solution
The output of the code will be 0.
Here's the step by step explanation:
- An integer variable
numis initialized with the value 0. - A
forloop is set up to run 8 times, withrowincrementing from 0 to 7. - Inside this
forloop, anotherforloop is set up to run from 0 to -1 (which is less than 0). However, since the condition for this loop to run iscol < 0, andcolis initialized to 0, this inner loop will never run. - Therefore,
num++inside the inner loop will never be executed. - After both loops have finished executing, the value of
num(which is still 0) is printed to the console.
So, the output of the code will be 0.
