Hello, why we are using append( ) method as :
s0.append( " I love c++ " );
and not like this :
append( s0, “I love c++” );
And similarly why we use empty as :
s0.empty( );
why we don’t use it as :
empty (s0);
What actually this ’ . ’ is doing in between s0 and method ?
Dot (.) operator is known as “Class Member Access Operator” in C++ programming language, it is used to access public members of a class . Public members contain data members (variables) and member functions (class methods) of a class.
the append and empty function are defined as such so we follow the syntax to implement them
Ok thanks
