A forward declaration is an identifier declaration (such as a class, function, or variable) to inform the compiler about its existence before it is defined. This allows you to use the identifier in situations where the order of declaration matters. ...

Declaration of structure pointer Just like another pointer variable declaration, a structure pointer can also be declared by precedingasterisk (*)character. The syntax is: structstructure_name*strcuture_pointer_variable; Here, structis the keyword which tells to the compiler that we are going to dec...
Note that for object types, the default value isnull, which means that the variable does not reference any object. If you try to access an uninitialized object variable, you will get aNullPointerExceptionat runtime: Stringstr;System.out.println(str);// throws NullPointerException ...
A forward declaration allows you to declare a variable of pointer type, but before you actually use it the compiler must see the complete definition. The error message indicates that this is not happening.May 3, 2009 at 1:38am Sundar0206 (14) how do i really get to solve this issue?
This declaration creates a variable, called count, that may point to a data object of type natural stored in memory. Initially, the variable has the value null. This is a special pointer value that does not point to any data object and is the default initial value for any access type. ...
