1.If cin and cout objects are in the 'iostream' , why do we need to declare it again using 'std' ?
2.are cout,cin,cerr,clog the only ones in the iostream?
3.under which categories do cin,cout and iostream fall? (library,object etc..)
4.can we use the same iostream for both linux and windows? how come?
- and where can I find the real code of iostream?
