How many hashes (+) does the code output to the screen?
- A . one
- B . zero (the code outputs nothing)
- C . five
- D . three
Correct Answer: C
C
Explanation:
The code snippet that you have sent is a loop that checks if a variable “floor” is less than or equal to 0 and prints a string accordingly.
The code is as follows:
floor = 5 while floor > 0: print(“+”) floor = floor – 1
The code starts with assigning the value 5 to the variable “floor”. Then, it enters a while loop that repeats as long as the condition “floor > 0” is true. Inside the loop, the code prints a “+” symbol to the screen, and then subtracts 1 from the value of “floor”. The loop ends when “floor” becomes 0 or negative, and the code exits.
The code outputs five “+” symbols to the screen, one for each iteration of the loop.
Therefore, the correct answer is C. five.
