Leading Blanks in Input


By default, std::cin ignores leading whitespaces when it reads input from the keyboard or file. For example, if you execute the following statement:
 
char name[10];
cin>>name;

and the user enters the following:
 
   Leon

The leading blanks are not inserted into name. You should be aware of this rule because strings with leading whitespaces will be trimmed and thus become shorter than you might expect.
