Organizing data with methods that operate on the data and creating a new data type is called encapsulation.

Inline function specifier reduces the overheads associated with a normal function call.

The new operator always returns a void pointer.

'this' pointer has to be used while accessing data members in a member function.

In C++, identifiers have to be declared at the beginning of the blocks.

In C++, an identifier must be initialized using constant expression.

Data objects can be initialized when allocating memory using 'new'.

Scope resolution operator has the highest precedence.

Reference to an object behaves like a constant pointer.

We can make function inline by using the keyword 'inline'.

Private members of a structure can be accessed directly from the outside of the structure.

The following syntax is valid. void inline gram_ panchayat :: show_gram_ panchayat_info().

The members of a class by default are private.

A copy constructor is used to copy an object member wise to another object of the same class.

Member function cannot be called from within a constructor.
