One important aspect of C++ that is related to operator precedence is theorder of evaluationand theorder of side effectsin expressions. In some circumstances, the order in which things happen is not defined. For example, consider the following code: floatx=1; x=x/++x; The value of <it><...
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

All comparison operators have equal precedence, and all have greater precedence than the logical and bitwise operators, but lower precedence than the arithmetic and concatenation operators. The logical and bitwise operators have the order of precedence described in the following section, and all have ...
, left to right The following notes provide further information to the above table: [1] The ++ and -- operators at this precedence level are the postfix flavors of the operators. [2] The ++ and -- operators at this precedence level are the prefix flavors of the operators. ...
Q2: How can I override operator precedence in C++? A2:Parentheses can be used to override default operator precedence in C++. Expressions enclosed in parentheses are evaluated first, allowing developers to explicitly control the order of operations. ...
b : c; because the precedence of arithmetic left shift is higher than the conditional operator. Notes Precedence and associativity are compile-time concepts and are independent from order of evaluation, which is a runtime concept. The standard itself doesn't specify precedence levels. They are ...
Because the order of subexpression evaluation is not specified, you can explicitly force the grouping of operands with operators by using parentheses. In the expression a + b * c / d the * and / operations are performed before + because of precedence. b is multiplied by c before it is ...
