Because strings are commonly used in programs, most modern languages include a built-in string data type.
Once that is done, we can define variables of type std:: In string form, numbers are treated as text, not numbers, and thus they can not be manipulated as numbers e. Any other characters are left inside cin, waiting for the next extraction.
