Which statement corrects the off-by-one error in the following code: # This code prints the first 10 numbers starting with zero i = 0 while i <= 10 : print(i) i = i + 1

• Replace |i = 0| with |i = 1|

• Replace |while i <= 10| with |while i < 10|

• Replace |i = i + 1| with |i = i + 2|

• Replace |while i <= 10| with |while i + 1< 10|

How many times will the following loop run? i = 0 while i < 10 : print(i) i = i + 1

The code snippet below is supposed to check whether an integer greater than 1 is a prime number. What will be the result of executing it? j = 2 result = 0 number = int(input("Please enter an integer (2 or greater):")) while j < number : if number % j == 0 : result = 1 j = j + 1 if result == 1 : print("Number:", number, "is Not Prime.") else : print("Number:", number, "is Prime.")

• The code snippet contains a compile error.

• The code snippet displays the desired result.

• The code snippet displays an incorrect result.

• The code snippet causes an infinite loop.

What is the output of the following code snippet? a = 2 n = 16 r = 1 b = a i = n while i > 0 : if i % 2 == 0 : # n is even b = b * b i = i / 2 else : r = r * b i = i - 1 print("r =", r)

• r = 16

• r = 128

• r = 4096

• r = 65536

• 0

• 62

• 63

• The code fragment displays no output because it does not compile.
