This is an example of _____ nested ______ for loops.2. When is `num1` in the outer loop incremented?### Explanation:In this C++ code, we have a main function that includes a nested loop structure. The outer loop initializes `num1` to 0 and runs as long as `num1` is less than or equal to 1, incrementing `num1` by 1 with each iteration. Inside the outer loop, there is an inner loop that initializes `num2` to 1 and runs while `num2` is less than 2, incrementing `num2` by 1 with each iteration.The `cout` statement inside the inner loop prints `num1` and `num2`, separated by a space, and then moves to a new line because of `endl`.The structure demonstrates the concept of nested loops, where one loop is placed inside another. It highlights how the inner loop completes all its iterations for each single iteration of the outer loop. Hence, the `num1` is incremented only after the inner loop has finished all its iterations for a given `num1`.

In the outer for loop first of all the loop control variable num1 is initalized . After that the…

1. This is an example of _____ nested ______ for loops.
2. When is `num1` in the outer loop incremented?

### Explanation:

In this C++ code, we have a main function that includes a nested loop structure. The outer loop initializes `num1` to 0 and runs as long as `num1` is less than or equal to 1, incrementing `num1` by 1 with each iteration. Inside the outer loop, there is an inner loop that initializes `num2` to 1 and runs while `num2` is less than 2, incrementing `num2` by 1 with each iteration.

The `cout` statement inside the inner loop prints `num1` and `num2`, separated by a space, and then moves to a new line because of `endl`.

The structure demonstrates the concept of nested loops, where one loop is placed inside another. It highlights how the inner loop completes all its iterations for each single iteration of the outer loop. Hence, the `num1` is incremented only after the inner loop has finished all its iterations for a given `num1`.
