Question
What would be output at the end of the following code segment? int num = 0; for(int row = 0; row < 7; row++ ) { for(int col = 0; col < 2; col++) { num++; } } System.out.println(num);a.)0b.)14c.)7d.)2
Solution
The output of the code would be 14.
Here's the step-by-step explanation:
- The variable
numis initialized to 0. - The outer loop runs 7 times because
rowis initialized to 0 and the loop continues as long asrowis less than 7. - For each iteration of the outer loop, the inner loop runs 2 times because
colis initialized to 0 and the loop continues as long ascolis less than 2. - During each iteration of the inner loop,
numis incremented by 1. - Therefore,
numis incremented a total of 14 times (7 iterations of the outer loop * 2 iterations of the inner loop). - The final value of
num(14) is printed.
So, the correct answer is b.)14.
