Question

A store sells rope only in whole-foot increments. Given three lengths of rope, in feet, the following code segment is intended to display the minimum length of rope, in feet, that must be purchased so that the rope is long enough to be cut into the three lengths. For example, for lengths of 2.8 feet, 3 feet, and 5 feet, the minimum length of rope that must be purchased is 11 feet. For these inputs, the code segment should display 11. As another example, for lengths of 1.1 feet, 3.2 feet, and 2 feet, the minimum length of rope that must be purchased is 7 feet. For these inputs, the code segment should display 7.
double len1
double len2 double len3; double total = lenl + len2 + len3; int minLength = (int) (total + 0.5); System.out.print(minLength);
Which of the following best describes the behavior of the code segment?
1. The code segment works as intended for all nonnegative values of lent, len2, and len3.
2. The code segment does not work as intended for some values of lent, len2, and len3. It could be corrected by casting lent, len2, and len3 to int before adding them together and assigning the sum to minLength. The code segment does not work as intended for any values of lent, len2, and len3. It returns the sum of 0.5 and the three lengths for all values of lent, len2, and len3. 3. The code segment works as intended but only when the sum of the three lengths is an integer or the decimal part of the sum of the three lengths is greater than or equal to 0.5. 4. The code segment does not work as intended for some values of lent, len2, and len3. It could be corrected by declaring minLength as a double and casting it to an int in the System.out.print statement.

Answer 1

Answer:

The correct option is option 3 which is The code segment works as intended but only when the sum of the three lengths is an integer or the decimal part of the sum of the three lengths is greater than or equal to 0.5.

Explanation:

As the variable minLength is defined as an integer thus the value is being truncated although the value of 0.5 is being added however if the decimal portion of the length is less than 0.5, the portion is truncated.

Answer 2

Answer:

Answer is option 3) The code segment works as intended but only when the sum of the three lengths is an integer or the decimal part of the sum of the three lengths is greater than or equal to 0.5. Therefore,

Refer below for the explanation.

Explanation:

As the integer minlength that will result as final output illustrates that the integer of three ropes added 0.5 in the final output minlength.
