The Correct Answer and Explanation is:
Correct Answer (MATLAB Function):
matlabCopyEditfunction onTime = CheckStatus(noTraffic, gasEmpty)
% Assign onTime with true if noTraffic is true and gasEmpty is false
onTime = noTraffic && ~gasEmpty;
end
Explanation
This function determines if a condition for being on time is met based on two logical inputs: noTraffic and gasEmpty. The variable onTime is assigned a logical value of true only when noTraffic is true and gasEmpty is false.
The statement:
matlabCopyEditonTime = noTraffic && ~gasEmpty;
uses logical operators to evaluate the required conditions. The && operator represents logical AND, meaning both conditions must be satisfied for the result to be true. The ~ symbol represents logical NOT, which inverts the value of gasEmpty. So, ~gasEmpty is true when the gas tank is not empty.
By combining both:
- If
noTrafficis true (indicating there is no traffic), and gasEmptyis false (indicating there is fuel),
then onTime is set to true, indicating that the scenario supports arriving on time. If either of the conditions fails, onTime becomes false, meaning that being on time cannot be guaranteed.
The function does not use conditional statements like if or else. It relies entirely on logical operators to make the evaluation concise and direct. Logical expressions such as these are often preferred in situations where binary conditions are involved, allowing clear and efficient computation.
This implementation ensures minimal code with maximum clarity. The logic is executed in one line, making the code both readable and functional without unnecessary complexity. This is suitable for automation or decision-making systems that depend on straightforward logical evaluations.
