precedence and associativity in c

introduced:The C and Pointers P83 page has an example: A*b+c*d+e*f, and for this example, the precedence and binding of the operator are explained. To facilitate the following instructions, we have numbered the operators in the above expressions:

The following table lists the precedence and associativity of C + + operators. Operators is listed top to bottom, in descending precedence. Precedence Operator Description associativity 1 :: Scope

C + + Operator precedence The operators at the top of this list are evaluated. Precedence Operator Description Example associativity 1 :: Scoping operator Class::age = 2; None 2

ArticleDirectory C ++ operator precedence C ++ operator precedence The operators at the top of this list are evaluated first. Precedence Operator Description Example Associativity 1 ::

Summary:This paper is a pioneering analysis of the role of sequence points in the evaluation of C-language expressions: The operand to the left of the sequence point is evaluated before its right operand. The comma operator, logic and operator &&,

Although, there is a certain C + + foundation (because the undergraduate has learned this kind, haha), but still decided to read the system of the book (before a few times before. Sweat).Leave it for your own reference later. (The content will be

Readers may suspect that something as simple as an if, a for, a while, a goto, or a switch should also be about programming style, is it a fuss? I really find that many programmers write expressions and basic statements in the wrong way, and I have

+ 、-、 *,/, = Priority 1. Priority level As with mathematics, C language stipulates multiplication and subtraction before adding and reducing . In other words, the multiplication and division operators have a higher precedence

An expression C + + provides a rich operator and defines what these operators mean when the operands are of a built-in type. In addition, C + + supports operator overloading, allowing programmers to customize the meaning of the operator when used
