Question 1

Examine the following lines of code:
Current = 1
Sum = 0
N = 5
While current <= n:
Sum = sum + current
Current = current + 1
This is an example of:
A) A definite loop
B) An indefinite loop
C) An infinite loop
D) Input error checking

Accepted Answer

This is an example of a definite loop because it iterates a known number of times, specifically from 1 to 5, incrementing the value of `current` each time until it exceeds `n`.

Question 2

Examine the following lines of code:
Which = input('Please enter 'F' or 'C')
While which != 'F' and which != 'C':
Which = input('Please enter 'F' or 'C')
This is an example of:
A) A definite loop
B) An indefinite loop
C) Correct syntax
D) Input error checking

Accepted Answer

The code is an example of an indefinite loop because it continues to prompt the user for input until a valid response ('F' or 'C') is entered.
