What is the number of iterations the following while loop will perform before terminating?
x = 4
while x < 4 + 6:
print(x)
x += 1
Instruction: Choose the option that best answers the question.
Options:
0, since we cannot include arithmetic operations in while loop conditions
Infinity
6
1
Answer (2)
The question is asking how many iterations a given while loop will perform before it terminates. Let's break down the loop to understand its behavior.
The initial value of x is set to 4. The condition in the while loop is x < 4 + 6 , which simplifies to x < 10 .
Here's how the loop will work step-by-step:
First Iteration:
Current value of x is 4.
The condition x < 10 is true (4 < 10), so the loop executes.
The value of x is printed (output: 4).
x is incremented by 1, so it becomes 5.
Second Iteration:
Current value of x is 5.
The condition x < 10 is true (5 < 10), so the loop executes.
The value of x is printed (output: 5).
x is incremented by 1, so it becomes 6.
Third Iteration:
Current value of x is 6.
The condition x < 10 is true (6 < 10), so the loop executes.
The value of x is printed (output: 6).
x is incremented by 1, so it becomes 7.
Fourth Iteration:
Current value of x is 7.
The condition x < 10 is true (7 < 10), so the loop executes.
The value of x is printed (output: 7).
x is incremented by 1, so it becomes 8.
Fifth Iteration:
Current value of x is 8.
The condition x < 10 is true (8 < 10), so the loop executes.
The value of x is printed (output: 8).
x is incremented by 1, so it becomes 9.
Sixth Iteration:
Current value of x is 9.
The condition x < 10 is true (9 < 10), so the loop executes.
The value of x is printed (output: 9).
x is incremented by 1, so it becomes 10.
Termination:
Current value of x is 10.
The condition x < 10 is false (10 < 10 is not true), so the loop terminates.
The loop runs a total of 6 iterations before terminating. Therefore, the correct answer is 6 .
The while loop will perform 6 iterations before terminating. It starts with x at 4 and continues until x is no longer less than 10. Therefore, the chosen option is 6 .
