Inserting an X into a table depending on user input

[asmtom]

In my program I have a table of mon-sun on top, and morning, noon night on the side. I want the user to insert which of the options they want, and then an "X" will appear in the alotted spot. Does anyone have any ideas on how to approach this problem?

What kind of application do you have in mind? A console application, windows application, ...?

An array could help you.

It's a console application, I'm just doing a first year C++ course, so it's out of Dev-C++. So far I have a certain places, "a", "b", "c" and have it so if it is not one of the ones selected, it just turns into a "-" and not an "X".
