How I can check if a variable is initialized?

[mp121209]

Hello,
I have a question,
If I have a variable, such as a pointer, but I don't know if it is initialized. Is there any method to check this?
For example, it likes

int *ptr;
if (isInitializedPointer(ptr))
   std::cout << "The pointer is available to use" << std::endl;
else
   std::cout << "The pointer is not already initialized" << std::endl;

Thanks for your helps!

I dont think any function is available to check .....

You should initialize it when you use it the first time.

just like:

int* ptr = 0;

But, isInitializedPointer(ptr) is useless in C++, you can get the value of ptr.

You can not get the initialized mark of it, there is no records, only if you mark it yourself.
