In C++ primer 4th 8.8.1 sections:

Why there is NO Copy or Assign for IO Objects? 

ofstream out1, out2;  
out1 = out2;              // error: cannot assign stream objects  
ofstream print(ofstream); // error: can't initialize the ofstream parameter  
out2 = print(out2);       // error: cannot copy stream objects

Can anyone tell me the reason? Thanks a lot.

The short answer is : it doesnt make sense to copy or reassign a C++ stream. The real question is: what are you trying to achieve exactly ?
