Create and record fake auto text processing program for a movie

Hello, I am making a short fiction movie for which I need footage of terminal running an auto text processing program in C++, similar to "Hello World" but with a variety of command lines that result in output that incorporates random blocks from a source text. I would provide the source text and need you to screen capture (video) and save the whole terminal output (the program's full activity log) which includes the mixture of code lines and fragments of the source text. Absolutely does not have to be perfect, it's meant to illustrate the idea of code generating on it's own including the words from the source text. Thanks so much!
