Which operator is used to compare two values for equality?

The operator used to compare two values for equality is the equality operator. This operator checks whether the values of two operands are the same and returns a Boolean value of true or false. In many programming languages, this is typically represented by the double equal sign (==). For instance, when evaluating the expression 5 == 5, the equality operator will confirm that both sides are equal, resulting in true.

In contrast, the assignment operator is primarily used to assign a value to a variable and does not compare values. The relational operator is broader, encompassing various comparisons such as less than, greater than, and not just equality. Lastly, the logical operator is used for logical conjunctions and disjunctions, helping evaluate truth values but not specifically for checking equality between two values. Thus, the equality operator is the precise tool for comparing two values to determine if they are equal.
