does not create anything; it declares a reference called result to a type CC and sets it equal
to *this, so now result and this are one and the same object.

CC result= *this;

ClassA::ClassA( const ClassA &from)
     :member1( from.member1 )
     ,member2( from.member2 )
     ,.... etc

int* x = new int[1000];

void foo(int i)
