|not_eq operator||Inequality operator|
equality-expr := equality-expr != relational-expr | equality-expr not_eq relational-expr
The not_eq operator compares two expressions for inequality. It returns true if the operands are different or false if they are the same. The not_eq keyword is interchangeable with the != token. Note that there is no keyword equivalent for the == operator.
