Operator Precedence Languages (OPL) are deterministic context-free and have desirable properties. OPL are parallely parsable, and, when structurally compatible, are closed under Boolean operations, concatenation
Operators that have the same precedence are bound to their arguments in the direction of their associativity. For example, the expressiona= b= c is parsed asa=(b= c), and not as(a= b)= c because of right-to-left associativity of assignment, buta+ b- c is parsed(a+ b)- c and ...
Operators that are in the same cell (there may be several rows of operators listed in a cell) are evaluated with the same precedence, in the given direction. For example, the expressions*p++anda=b=care parsed as*(p++)anda=(b=c), and not as(*p)++or(a=b)=cbecause of right-to-le...
Any language expression consists of operands (variables, constants, etc.) connected with each other by operators. Operations are executed in a strict order. The value that determines a privilege to execute a certain operation is called precedence. The op

Understanding the '-->' Operator in C: Explanation and Example The --> is not actually an operator in C language. However, there’s a bit of a trick behind why this might appear to work in some contexts due to operator precedence and the way the compiler interprets it. Let’s dive ...
When several operations occur in an expression, each part is evaluated and resolved in a predetermined order calledoperator precedence. Precedence Rules When expressions contain operators from more than one category, they are evaluated according to the following rules: ...
