So yeah, as alot of you will know Im Currently Learning C++ and I have come to my first problem out of many that will come.

That is: How do I check the type of a C++ data type variable?

typeof is provided by the GNU Compiler Set. As for Microsoft C ... *shrug*.

Short answer, you really should not.

Types and Classes are hard-coded in. Compiled. And they are generally not needed at runtime.

Example:
class MyClass;
class MyOtherClass;

int main() {

    MyClass object; //We know that this is of type MyClass, it cannot (in general) be changed (type-casted)

    MyOtherClass another_object; //This is a different object that is (generally) always of type MyOtherClass

}


If you tell me exactly what you are trying to accomplish than I will be able to help you out more.

I realized my explanation sounded like crap. So I made it different and hopefully better.

If you design your classes and such correctly there should be little to no need for typeof.

Agreed, it's not a C++ standard either, which means plenty of "bugger" moments when attempting to use it on Microsoft C, Borland C etc etc.

Thanks for the Example, But I had escaped this Problem earlier so there was no need. Thanks anyway though.
