@teja:
if we use call by value in copy constructor,,
class base
{
int a;
public:
base(int x)
{
a=x;
}
base(base c)
{
}
};
int main()
{
base b(1);
base b1=b;// this ll be seen as base c=b(see the copy constructor)..this ll
in turn call another copy constructor..
return 0;
}
now it ll create a separate object each time you call a copy constructor..so
it ll result in infinite loop..so we have to pass by reference..
