Question

If the following program is supposed to put down three tennis balls, where is the logic error?

1 def place_three_ball():
2 for i in range(4):
3 put_ball()
4
5 placeThreeBalls()

A. Line 1
B. Line 2
C. Line 3
D. Line 5

Answer 1

The logic error is on line 2 of the program, where range(4) should be range(3) to ensure that only three tennis balls are placed down, not four.

Step-by-step explanation:

The logic error in the program that is supposed to put down three tennis balls is on line 2. The range function in Python starts at 0 and goes up to, but does not include, the specified end value. By using range(4), the loop will iterate four times, which will result in four calls to put_ball(), not three.

To fix this error, the range() function should be called with an argument of 3, so that the loop iterates three times, and three balls are placed as intended.

The logic error in the given program is on line 2.

The program uses the range(4) function, which generates numbers from 0 to 3. Since the loop runs 4 times, it will execute the put_ball() function one extra time, resulting in four balls being put down instead of three.

To fix this logic error, you should change range(4) to range(3) on line 2. This will make the loop run only three times, putting down three tennis balls as intended.
