In plain words
Cpi is a tiny C++ interpreter that allows users to compile and execute C++ programs immediately like a scripting language. It uses an internal compiler to interpret code without requiring separate compilation steps. The tool is built with Qt and works on Windows and Unix-like systems, supporting rapid development and testing of C++ scripts.
