A function can return a reference.Returning a reference can be very useful when you are overloading certain types of operators.
However,it also can be employed to allow a function to be  used on the left side of an assignment statement.


int &f( )//return a reference
int x;
int main( )
f( )=100; //assigning 100 to reference returned by f()
cout<< x <<"\n";
return 0;
//return an int reference.
int &f()
return x;  //return a reference to x
