DECLARE@MyNumberINT;SET@MyNumber =4-2+27;-- Evaluates to 2 + 27 which yields an expression result of 29.SELECT@MyNumber; Use parentheses to override the defined precedence of the operators in an expression. Everything within parentheses is evaluated to yield a single value. That value can...
Operators that have the same precedence are bound to their arguments in the direction of their associativity. For example, the expressiona=b=cis parsed asa=(b=c), and not as(a=b)=cbecause of right-to-left associativity of assignment, buta+b-cis parsed(a+b)-cand nota+(b-c)because of...
Operators with higher precedence are evaluated first. consider this: (2+2)*9 = 4*9 = 36 2+2*9 = 2+18 = 20 Because () have more precedence than + and * 18th Jun 2017, 5:00 AM Nithiwat + 4 Ehhh not really 'choose', more or less 'make' with use of brackets. It's just ...
The below table is primarily meant to be a reference chart that you can refer back to in the future to resolve any precedence or associativity questions you have. Notes: Precedence level 1 is the highest precedence level, and level 17 is the lowest. Operators with a higher precedence level ...

Operator Precedence in C - A single expression in C may have multiple operators of different types. The C compiler evaluates its value based on the operator precedence and associativity of operators.
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 expression a=b=c is parsed as a=(b=c), and not as (a=b)=c because of right-to-left associativity. Notes...

A link tohttp://cpp.operator-precedence.comwas added to this page, presumably with the idea that it would be useful to have a simpler view of this chart. I've tentatively reverted the change, just to make sure it's not linkbait. Is such a link useful? Alternatively, could this chart...
