Doubt in string class

#1

Hello, I want to know that why we write empty function with a dot.

s0.empty( );

why we don’t write it as empty( s0);

#2

hello @yashsharma4304

bro it needs some knowledge of classes and objects.

s0 is an object and empty is its member function .
to call any function of a class using object we use dot.
thats why so.empty()
