If an array has a constant expression [2] (an expression that can be evaluated at compile time) as its bounds or empty braces (only permitted in a few contexts), then the array is not a VLA and has the same semantics such arrays have always had in C.

如果一个数组以常量表达式[2]（能够在编译时求值的表达式）或是空括号作为边界，那么这个数组不是VLA并且跟一直在C中的数组拥有相同的语义。

At a minimum, it is nearly always a good idea to use braces after an if when the statement in the body is anything other than a simple expression statement, such as an assignment or output expression.

至少，无论 if后面是简单语句，例如赋值和输出语句，还是其他任意语句，使用花括号都是一个比较好的做法。

We cannot always have associative law for operations, for instance, we did not have this law for mixed addition and multiplication,neither for subtraction, 2+3 2+1≠(2+3)(2+1)=5 3,（2-3）- 2≠2-（3-2）,this is why we have to set the rule in operations that "doing inside bracket at first and out side afterwards, doing multiplication and dividing first and addition and subtraction afterwards".

注意运算的结合律并不是永远对的，比如加法和乘法的混合运算就没有结合律，减法也没有，2+3 2+1≠5 3，（2-3）- 2≠2-（3-2），因此我们运算中总是规定先括号内再括号外，先加减后乘除。

In programming languages , the associativity of an operator is a property that determines how operators of the same precedence are grouped in the absence of parentheses.

在程序设计语言中，操作符的结合性用于在缺少括号的情况下，如何确定相同优先级的操作符的被分组的情况。
