Which of the following code segments can be used to update the values of the variables as shown in the table?
A
temp ← word1
word3 ← word1
word1 ← temp
B
temp ← word1
word1 ← word3
word3 ← temp
C
temp ← word1
word1 ← word2
word3 ← temp
D
temp ← word3
word1 ← word2
word2 ← temp
To determine which code segment can update the values of the variables as specified in the table, we need to analyze how each segment manipulates the variables.
Assuming the goal is to swap two variables while keeping the third one intact, let’s briefly analyze the options:
– A: This segment stores `word1` in `temp`, assigns `temp` to `word3`, then assigns `word1` back to `temp`, which doesn’t help us achieve a useful update.
– B: Here, `temp` stores `word1`, then `word1` is replaced by `word3`, and finally `word3` is set to `temp`. This effectively swaps `word1` and `word3`.
– C: This segment replaces `word1` with `word2` and assigns `word1` to `temp`, but doesn’t achieve the desired update.
– D: This effectively replaces `word1` and `word2`, but does not interact with `word3`.
Based on this analysis, B is the correct choice because it effectively swaps the values of `word1` and `word3`, maintaining the integrity of the swap process.
In conclusion, the code segment that can be used to update the values of the variables as shown is B.
