WebOne of the great strengths of C++ is its I/O system, IO Streams. As Bjarne Stroustrup says in his book "The C++ Programming Language", "Designing and implementing a general input/output facility for a programming language is notoriously difficult". He did an excellent job, and the C++ IOstreams library is part of the reason for C++'s success.
