赋值表达式

Only assignable expressions can be used to pass var and out parameters.

只有可赋值的表达式可以被用于传递 var 参数和 out 参数。

In Python, assignment is not an expression.

在python中，赋值不是一个表达式。

In an assignment, Python requires an expression on the righthand side of the =.

在一个赋值中，python要求等号右边是一个表达式。

Finally we can write out the verification condition of a path according to some rule, depending on assertion of the path's start point, assertion of the path's end point, condition expression and assignment statement of the path.

最后，有了路径起始断点的断言，路径的条件表达式、赋值语句，路径的终止断点的断言，按照一定的规则就写出了这条路经所对应的验证公式。

Like the rule, the expression after assignment operator = defines the subrule

类似于规则，赋值号=后面的表达式定义了子规则

Likewise, the second assignment successfully converts the lambda expression to the delegate type Func because the result of x+1 is implicitly convertible to type double.

同样第二个赋值成功地转换 lambda 表达式到 delegate 类型 Func ，是因为 x+1的返回值是隐式转换成 double 的。

Due to historical reasons, note that the alternate VarAdd syntax listed above matches neither the syntax for variable assignment within an expression, nor the syntax for variable addition within an expression.

由于历史原因，注意上面列出的VarAdd可代替语法既不能将变量赋值用于表达式内，也不能将变量加用于表达式内。

The first assignment successfully converts the lambda expression to the delegate type Func because, when x is given type int, x+1 is a valid expression that is implicitly convertible to type int.

第一个赋值成功地转换 lambda 表达式到 delegate 类型 Func ，是因为当 x 是 int 型， x+1 是一个有效的表达式并可以隐式地转换到类型 int 。

The value of an expression shall be the same under any order of evaluation that the standard permits.

12.2 在标准允许的任何赋值顺序下表达式的值都必须相等。

Assignment operators shall not be used in expressions that yield a Boolean value.

1313.1 在产生布尔值的表达式中不能使用赋值操作符。

Do you know, i need you to come back

你知道吗，我需要你回来
