lvalue

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

提供一个左值迭代器而不是读写迭代器有什么好处?

An identifier is a modifiable lvalue if it refers to a memory structure, union , or pointer.

涉及到在内存中的地址的表达式称为左值表达式.

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

说得更具体一些, 计算左值表达式就会产生对象.

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

解引用返回左值，因此可将解引用操作符用作赋值操作的左操作数。

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

任务声明中的lvalue与rvalue由一个冒号加等号隔离开来（：=）。

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

与下标和解引用操作符一样，赋值操作也返回左值。

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

分配声明中的lvalue和rvalue以：=（冒号加等号）被隔开。
