Answer:
The first value of i is 0 and last value of i is 20.
Explanation:
The following are the description of a given loop.
- In this problem, there are two loops one is the internal loop and the other is the external loop
- In the outer loop, the value of " i" is initialized with "0" So the first value is printed 0 in the console.
- For one value of "i" all the inner loop is executed.
- The loop is executed is less equal to 20 that's why the last value of "i" is printed 20 in the console window.
I am assuming this is a true or false question? If so, the answer is true.
