Which operator checks for less than or equal to?

• A. Less than
• B. Less than or equal to
• C. Not equal to
• D. Equal to

Answer: (B)

The operator that checks for less than or equal to compares two values and returns true when the first value is either smaller than the second or exactly the same as the second. It’s usually written as <=. This is useful in conditions where you want to include the equality case, such as deciding whether a value falls within a range or should continue a loop.

For example, if x is 5 and y is 7, x <= y is true. If x and y are both 5, x <= y is also true. If x is 8 and y is 7, x <= y is false.

The other options don’t fit this check: the strict less-than operator (<) would be false when the values are equal; the not-equal operator (!=) checks whether they are different; the equal-to operator (==) checks whether they are the same, not whether one is less than or equal to the other.
