C+ +没有提供查询变量或表达式的类型的简便方法。
C + + has never had an easy mechanism for querying the type of a variable or an expression.
默认指定的子句可以为一个常量、一个特殊的寄存器、另一个全局变量、一个表达式或关键字NULL。
The default clause specified can be either a constant, a special register, another global variable, an expression or the keyword NULL.
XPath表达式使用动态定类型(在对表达式或变量求值之前，不必知道表达式或变量的类型)。
XPath expressions use dynamic typing (the type of an expression or of a variable is not necessarily known until the expression or variable is evaluated).
这意味着通过引用正则表达式(或者甚至是一段代码)，变量会拒绝将其值设置为某些恶意的值或完全无意义值的尝试。
This means that a variable may reject attempts to set its value to something malicious or simply nonsensical by referring to a regular expression (or even a piece of code).
然后表达式中对变量的引用可以静态绑定到本地堆栈框架或一列全局变量的特定槽上。
References to variables within an expression can then be statically bound to a particular slot in either the local stack frame or the list of global variables.
二者的实现基础完全相同，即在编译时将“var”替换成为分析得到的正确的变量或数组类型表达式。
Both work fundamentally the same way, at compile time the keyword "var" is replaced with the correct scalar or array type for the associated expression.
对于大多数Shell，人们经常提到的局限性之一在于，它们具有松散的变量类型、没有数据数组支持、没有用于执行基本的数学或表达式计算的内置功能。
One of the commonly quoted limitations of most shells is that they have loose variable typing, no support for arrays of data, and no built-in functionality to perform basic math or expressions.
一种常数、变量、函数名或表达式。
默认指定的子句可以为一个常量、一个特殊的寄存器、另一个全局变量、一个表达式或关键字NULL。
The default clause specified can be either a constant, a special register, another global variable, an expression or the keyword NULL.
表达式可以简单到就是一个变量（如清单2 所示）或者是一个方法调用（例如getList()），亦或是包含布尔逻辑或三目运算符的复杂表达式。
This expression can be as simple as a variable (as shown in Listing 2) or a method call (like getList()), or a complex expression that involves boolean logic or a ternary operator.
value属性可以是文本字符、变量或变量外加一个定制的正则表达式。
The value attribute may be literal characters, variables, or variables plus a customized regular expression.
这些语句也规定程序员可以选择的变量与参数种类，以及当一个表达式使用过程或函数时代码将返回的值的类型。
These statements also define the kinds of variables and parameters the programmer can choose and the type of value that the code will return when an expression accesses the procedure or function.
value值可以包含文本字符、变量或具有定制正则表达式的变量。
The value attribute can contain literal characters, variables, and variables with custom regular expressions.
一种常数、变量、函数名或表达式。
表达式，计算为包含环境变量名称的字符串，或对应于环境字符串表中环境字符串的数字顺序的整数。
Expression that evaluates either a string containing the name of an environment variable, or an integer corresponding to the numeric order of an environment string in the environment-string table.
将表达式或其一部分的结果存入一个临时变量，临时变量的名字用来解释其用途。
Put the result of the expression, or parts of the expression, in a temporary variable with a name that explains the purpose.
如果表达式表示类或结构，则将作为表达式对象来检索成员变量列表。
If the expression represents a class or structure, retrieve a list of member variables, as expression objects.
标准C允许使用需要引用自身的表达式初始化对象或变量，但只适用于非静态作用域的对象。
Standard C allows for the initialization of an object or variable with an expression involving a reference to itself, but only for objects of nonstatic extent.
从过程返回的值可以像变量或常数的值一样参与到表达式中。
The value returned from the procedure participates in the expression just as the value of a variable or constant would.
计算某些表达式可以更改变量的值，或会影响程序的状态。
Evaluating some expressions can change the value of a variable or otherwise affect the state of your program.
自增自减运算是C语言常用的运算，它只能作用于变量，不能作用于常量或表达式。
Self-increase operation and the self-reduction operation are the operations used in C language, they can only act on the variable, not act on the constant or the expression.
本文中，我们以经典风险模型为基础构造了三类风险模型并且对其进行研究，得到了与破产相关的一些变量的表达式或性质。
In this text, based on the classical risk model, we construct and research three kinds of new risk models. Finally we obtain some expressions or characters of the variables about ruin.
如果相应语句为某个表达式赋值，请用一个可写的变量、属性或数组元素替换该表达式。
If the statement assigns a value to an expression, replace the expression with a single writable variable, property, or array element.
在不允许输入有反变量和不考虑竞争冒险的情况下，一般不能从最简或非——或非表达式来找最小化或非逻辑网络。
When it is under the condition that no input inversion is allowed and no competition and hazard are considered, the minimization Nor logic Network can not be derived from the simplest Nor-Nor formula.
本文中我们在经典风险模型的基础上构造了三类随机变量具有相依性的风险模型并对它们进行了研究，得到了与破产相关的一些变量的表达式或性质。
In this text, based on the classical risk model, we construct and research three kinds of new risk models with dependence. Finally we obtain some expressions or characters of the variables about ruin.
如果正在用本机代码编程，有时可能需要限定变量名或包含变量名的表达式的上下文。
If you are programming in native code, you might sometimes have to qualify the context of a variable name or an expression that contains a variable name.
