I'll show you how to create an interactive program that reads your name and prints a greeting. The program will ask for your name, wait for you to type it, then say hello with your name included in the message.
You'll learn to use cin, which is like cout but for input instead of output. While cout sends information to the screen, cin receives information from the keyboard. They work together to make programs interactive.
This problem teaches you about variables, which are containers that store information. I'll create a string variable to hold the name you type, then use that variable in the greeting message.
