Why isn't my terminal returning anything?

I'm making a university project in C++ on VSCode (Windows), but I can't get the terminal to display anything. It worked for all my previous assignments, but suddenly it's giving me trouble. I type in the command to compile my script into a .exe file, and nothing happens. It just opens the same command prompt. I really need to contribute to this project, so any help at all is appreciated. I've tried restarting my PC and reinstalling VSCode but neither work
