C++ も C と同様に組み込み型の入出力文はありません。その代わりに、入出力機能はライブラリで提供されています。C++ の標準入出力ライブラリは iostream ライブラリです。 The file [code ]iostream.h[/code] is indeed a header file. It is not part of standard C++, however.

Get project updates, sponsored content from A Gentle Introduction to C++ IO Streams By Manasij Mukherjee One 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". Some things that you should check: Check the include folder in your version of VS (in "C:\Program Files\Microsoft Visual Studio xx.x\VC\include" check for the file which you are including, iostream, make sure it's there). However, that header has never been a standard C++ header.
