Instance of class cann’t access member of the class within the class

“Clubing data member and member function known as class.”

lets take an Example

Class A

{

Data member;

Member function;

}

If we create instance of the class in other class, that instance cannot access member of the class

lets take an Example

Class B

{

A  obj=new A();

A.Datamember;  // Error  instance member cann’t access datamember within the class

}

Solution :

Every executable statementmust be in a definition block( inside a function , constructor)

Class B

{

A obj =new A();

Public B()

{

Obj.DataMember=value; // you can access the datamember

}
