A(n) ________ operator determines whether a specific relationship exists between two values.

Relational operators have left to right associativity. Left to right associativity means that when two operators of same precedence are adjacent, the left most operator is evaluated first.

Relational OperatorsMeaning>Greater than=Greater than or equal to y

x == y

Note: It can be easy to forget that equal to is “==” and not “=” which is assignment.  In many cases, the compiler won’t note this as an error because x==y and x=y are both valid expressions.

What is the result of a relational expression?

Relational expressions are Boolean expressions and thus are equal to either true or false.

How a program treats true and false

C++ programs store true and false in memory as numbers.

false is stored as 0

true is stored as 1

Relational operator precedence and relationship to the other operators

Note how the relational operators rank in precedence to the mathematical and assignment operators. Also, note that the less than/greater than operators have higher precedence than the equal/not equal relational operators.
