如果表达式

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。

If a function foo{} is part of, say, assignment expression, it is considered a function expression.

如果function foo{}是一个赋值表达式的一部分，他就被认为是函数表达式。

If the dollar sign ends a regular expression, the expression is matched only at the end of a line.

如果美元符号在正则表达式末出现，该表达式只会在遇到行末的时候出现。

On the other hand, it is expressible as a Boolean expression if you accept including function calls in the Boolean expression.

但换个角度，如果你允许在布尔表达式中植入包含函数调用，则它就是一个布尔表达式可表述的属性。

If more than one operand of an expression raises an error, the implementation may choose which error is raised by the expression.

如果一个表达式有一个以上的操作数引发错误，实现可以选择哪一个错误被该表达式引发。

If len is non-zero then *m is filled in with what matched the regular expression, m[0] contains what matched the whole string, m[1] the first sub-expression etc, see regmatch_t in the header file declaration for more details.

如果 len 不是 0，那么*m 被填充为正则表达式匹配的结果， m[0] 包含整个字符串匹配的结果， m[1] 是第一个子表达式匹配的结果，依此类推，更多细节参见 regmatch_t 在头文件中的声明。

If a procedure is called with an expression in the place of a formal parameter, the compiler generates a thunk which computes the expression and leaves the address of the result in some standard location.

如果一个程序在被呼叫的时候，用一个表达式占据了形参的位置，那么编译器就会产生一个thunk，这个thunk指的是：计算表达式的地址，然后把这个地址放在适宜的位置。

If a variable declaration includes an expression but not an explicit type, the static type of the variable is inferred from the static type of the expression.

如果变量声明中包含一个不是显式类型的表达式，变量的静态类型将通过表达式的静态类型来推断。

Only the first parenthesized group in the regular expression will be recognized; if you can't express everything you want that way, you can return multiple regular expressions, each of which contains a parenthesized group to be matched.

只有在正则表达式中的第一个括号组被识别；如果你不能以此方法表达你想要的东西，你可以返回多个正则表达式，其中每个正则表达式都包含一个用于匹配的括号组。

In this for, the expression uses the prefix increment operator, which as we know adds one to the value of val. After executing the expression , the for retests the condition . If the new value of val is still less than or equal to 10, then the for loop body is executed and val is incremented again. Execution continues until the condition fails.

在这个 for 循环中，表达式使用前自增操作符， val 的值加 1，执行完表达式后， for 语句重新测试条件，如果 val 的新值仍小于或等于 10，则执行 for 语句体， val 再次自增，继续执行直到条件不成立。

In this section we look at the theory behind the techniques used in rotary polishing and the effects that they have on paintwork and the results achieved.

在这里看抛光剂使用背后的理论，到底是怎么一回事，我们如何用好的抛光机和好的使用技巧来达到好的效果。
