你好，Variable+'n'+is+never+used是定义局部变量，就会报“变量定义了，但是没有使用”的警告！，，并且变量也没有被赋值。很容易迷惑人。把变量改为全局变量后，就不会有警告了。或者在定义的前面加上 volatile 后，编译就通过了。这个和编译器的库有关。

you think you are arguing. In most situations, the compiler is perfectly aware of the complete lifetime of an object at compile time. If you assign a value to a local variable and the function ends, then you clearly have a case of "variable...
An application has at least one possible path through its code that reads a variable before any value is assigned to it.If a variable has never been assigned a value, it holds the default value for its data type. For a reference data type, that default value is Nothing (Visual Basic...
