The editor shows sample boilerplate code when you choose language as C++ and start coding! Read inputs from stdin OneCompiler's C++ online compiler supports stdin and users can give inputs to programs using ... The easiest solution is probably to create a local header file called iostream.h which just includes < iostream > and imports the namespace std. Then, in order for the compiler to allow #include you add the local path to your include file search path. For g++, this works: g++ -I local_folder [other flags] … Incidentally, your remark about … the deprecated " #include iostream.h " isn’t quite correct: this isn’t deprecated because it has never been legal C++. # include < iostream > # include # include The preprocessor searches in an implementation-dependent manner, normally in search directories pre-designated by the compiler/IDE. This means the compiler will search in locations where standard library headers are residing. The header files can be found at default locations like /usr/ include or /usr/local/ include . This method is normally used to include standard library header files. Example: Below is the C++ program to demonstrate ... Topics Covered iostream stands for standard input-output stream. # include iostream declares objects that control reading from and writing to the standard streams. In other words, the iostream library is an object-oriented library that provides input and output functionality using streams. A stream is a sequence of bytes.
