Question

Refer to the following python code snippet:

a = 100

b = 1

c = 5

while a > 1:

b += 1

a*=0.5

print(b,c)

What is b?

flag
sentinel value
counter
boolean

Answer 1

In the provided Python code, 'b' functions as a counter, which is used to count the number of times the while loop has executed.

Step-by-step explanation:

The Python code snippet you provided shows a while loop that executes as long as the value of a is greater than 1. During each iteration of the loop, b is incremented by 1, and a is halved (a is multiplied by 0.5). The loop runs until a becomes 1 or less, at which point the final values of b and c are printed.

In terms of the given options, b serves as a counter. A counter is a variable used to count the number of times a loop has executed. It starts with an initial value (in this case, 1) and is incremented by a certain amount (in this case, 1) each time the loop body is executed.

The code snippet provided in the question is written in Python. It initializes three variables, a, b, and c, with the values 100, 1, and 5 respectively. The while loop executes as long as the value of a is greater than 1. Inside the loop, b is incremented by 1 and a is multiplied by 0.5. The final values of b and c are printed.
