Console is not printing on multiple lessons, despite lesson allowing me forward

I’m new and picking up the basic C++ classes, though when I try to print anything to the console (i.e. “Hello World” and others) it does not print anything at all. It still says I pass the step and it allows me to move forward to the next page or lesson, but I am simply not seeing any of my code results on the console, even when I compile and execute it.
Is this an issue with my browser, or something wrong with the lessons I’ve chosen? I have tried both Firefox and Chrome and neither of them are showing my console results.
