getline: Another Method of Taking Input in C Plus Plus

In previous lessons we have learn that the keyword cin is used to get input from the user. But I want to tell you something about cin keyword that is very important to know. The keyword cin separates the words or "group of characters differentiated by spaces". It only keeps the first group of characters (or first word) and ignores the rest of the characters coming after the space.
