'class' keyword in variable definition in C++

What does the following variable definition mean?

class MyClass* myClass;

I tried running the code class MyClass* myClass = new MyClass(); and found that it simply creates a pointer to a new instance of MyClass.

What is the purpose of using the class prefix here? Does it make any difference?

Solution

  • An elaborated type specifier is a type name preceded by either the class, struct, enum, or union keyword. 

    class identifier 
struct identifier 
enum identifier 
union identifier

    An elaborated type specifier is used either for emphasis, or to reveal a type name that is hidden by the declaration of a variable with the same name in the same scope.
