Console. WriteLine indicates to write a string to the Console and then wrap it.
Console. Read indicates reading strings from the Console without line breaks.
Console. ReadLine indicates reading strings from the Console and wrapping them.
Console. ReadKey gets the next character or function key that the user presses. The pressed key is displayed in the Console window.
