Question

Question 26 options:

How many times will the while loop execute? Type the answer as an integer, "infinity" or "unknown".

int x = 3;
while (x < 370)
{
System.out.print(x + " ");
x *= x;
}

Answer 1

The while loop will run 3 times.

Explanation:

The while loop runs as long as the condition specified is true.

The condition in the code is x<370

So while loop will keep running till x remains less than 370 .

1st run:

1. x is 3 which is less than 370.
2. System.out.print will display the value 3 in output
3. The value of x will then change to 3 (3*3)

2nd run:

1. x is 9 which is less than 370.
2. System.out.print will display the value 9 in output
3. The value of x will then change to 81(9*9)

3rd run:

1. x is 81 which is less than 370.
2. System.out.print will display the value 81 in output
3. The value of x will then change to 6561 (81*81)

After the 3rd run the while loop will be terminated as the value of x will be 6561 will is not less than 370.

Output of the above code is:

3 9 81
