Overview

realcsh.c is an interactive shell that runs C++ source code. A line of input is handled as a line in main() function, and the resulting C++ code is compiled, and executed.

If a line starting with # such as #include <iostream> is entered, it is added to every code after that at the start of sourcecode.

The list of such lines can be seen with ##
