I have been doing some reading, and I see that I can use getch() to get a keystroke. What I have seen is that this is considered bad practice, however I have seen conflicting opinions. I am writing a console application for my class, and would like to be able to move a marker(*) around the screen based on the arrow keys being pressed. Is getch() the right way to go about this, or is there a better method to capture it. I want them to just be able to push the arrow, not need to push enter or anything. I don’t need the code specifically, I just want to know if I should avoid getch(), and if so, what functions are there for this type of idea.

getch()is not a standard function in either C or C++. It’s found in some obsolete compilers, such as Turbo C and it’s also defined in certain commonly used libraries such as curses, but in any case it’s a C function, not C++. For C++ you should probably just stick with standard C++ I/O. If you can’t do this for some reason then go for the most portable option, e.g. curses.
