lvalue

lvalue

 英

  • 網絡左值;理解左值;左值表達式

例句

The address-of operator. Takes a single argument that must be an lvalue . Yields the address in memory of that object.

地址操作符需要一個操作唯一操作必須對象操作返回操作對象內存存儲地址

Like the subscript and dereference operators, assignment returns an lvalue .

和解引用操作符一樣賦值操作返回

It explains the difference between an object and a name and how they relate to the notion of an lvalue .

本章解釋對象名字區(qū)別以及它們怎樣概念聯(lián)系

Dereference returns an lvalue, so we may use a dereference operator as the left-hand operand of an assignment.

引用返回因此引用操作符用作操作操作

An Object is a named region of storage; an lvalue is an expression referring to an object.

這時候可以解釋對象一個命名存儲區(qū)域對象引用表達式

In general, the left-hand side of an assignment operator always requires an lvalue .

一般賦值運算符左邊總是需要一個

The lvalue and rvalue in the assignment statement is separated by a : = (colon plus equal sign).

分配聲明lvaluervalue:=(冒號等號隔開

What are the benefits of offering a LValue iterator against a Read Write iterator?

提供一個不是讀寫什么好處

You might think of lvalue as meaning location value.

可以看作位置

More specifically, evaluating an expression that is an lvalue yields an object.

具體一些計算表達式產生對象

A modifiable lvalue cannot have an array type, an incomplete type, or a type with the const attribute.

更改不能為數類型、(聲明完善類型或者具有常量屬性類型

Name one case where an lvalue is required.

舉出一個需要例子

The subroutines chapter covers new syntax (prototypes and attributes), plus the brand new lvalue attribute (as of 5. 6. 0).

程序主要針對語法原型屬性),以及屬性(5.6.0)。

Instead of magic indexes, we get meaningful names (such as v: val. lval for each line's lvalue and line. op for each line's operator).

使用神奇索引我們獲得意義名稱例如,v:val.lval用于lvalue,line.op用于操作符)。

Some operators, such as assignment, require that one of their operands be an lvalue.

有些操作符比如賦值要求其中一個操作必須
