First impressions are rarely the best, but they are certainly what we remember for the rest of our lives. We're talking about programming, in case you were wondering. In this task, we will try to calculate the square of a number, display it on the screen, and also use the ability to read data from the keyboard (the user will enter the number while the program is running).
You can't complete this task, because you're not signed in.
