What will the result of num1 variable after execution of the following statements?int j = 1, num1 = 4;while (++j <= 10){num1++;}

The initial value of num1 is 4 and j is 1. The while loop will increment j by 1 and check if it's less than or equal to 10. If true, it will increment num1 by 1. This will continue until j is no longer less than or equal to 10.

Here's the step by step breakdown:

1. Initial values: j = 1, num1 = 4
2. First loop: j becomes 2 (j++), j is less than or equal to 10, so num1 becomes 5 (num1++)
3. Second loop: j becomes 3, j is less than or equal to 10, so num1 becomes 6
4. This continues until j becomes 10, at which point num1 is 13
5. On the next loop, j becomes 11, which is not less than or equal to 10, so the loop ends

So, after the execution of the statements, the value of num1 will be 13.
