g++ main.cpp foo.cpp bar.cpp -o program && ./programThe package library used in this example is likely GNU C++ Compiler (g++). In conclusion, cpp invocation is an essential tool for compiling and running C++ programs through a command line interface, and the package library used will depend on the specific compiler and tools being used.
