Question

All my questions are from c++

The code presented is a segment written in C++. It contains nested loops and a conditional statement, and the task is to determine what will be displayed on the console when `j = 2`. Here’s a breakdown and transcription of the code: ```cpp for (int j = 1; j < 4; j++) { for (int k = 1; k <= j; k++) { if (j * k > 3) break; cout << j * k << endl; } cout << j % 2 << endl; } ``` ### Explanation: - **Outer Loop (`for (int j = 1; j < 4; j++)`)**: This loop iterates with `j` starting at 1 and increments by 1 until `j` is 3. However, the problem specifies checking when `j = 2`. - **Inner Loop (`for (int k = 1; k <= j; k++)`)**: For each value of `j`, `k` starts at 1 and goes up to `j`. - **Conditional (`if (j * k > 3)`)**: - If the product of `j` and `k` is greater than 3, the `break` statement exits the inner loop. - **Output (`cout`)**: - Inside the inner loop, `cout << j * k << endl;` prints the product of `j` and `k`. - After the inner loop, `cout << j % 2 << endl;` prints the remainder when `j` is divided by 2. ### Output for `j = 2`: - **Inner Loop Execution**: - When `j = 2`, `k` ranges from 1 to 2. - For `k = 1`, `j * k = 2`, which is not greater than 3, so `2` is printed. - For `k = 2`, `j * k = 4`, which is greater than 3, causing the break, and the inner loop ends. - **Outer Loop Execution**: - After breaking out of the inner loop, `j % 2 == 0` is evaluated, and `0` is printed. Therefore, the complete output when `j = 2` is: ``` 2 0
