| Resize string Resizes the string to a length of n characters. If n is smaller than the current string length, the current value is shortened to its first n character, removing the characters beyond the nth. If n is greater than the current string length, the current content is extended by inserting at the end as many characters as needed to reach a size of n. If c is specified, the new elements are initialized as copies of c; otherwise, they are value-initialized characters (null characters). Parameters n New string length, expressed in number of characters. size_t is an unsigned integral type (the same as member type string::size_type). c Character used to fill the new character space added to the string (in case the string is expanded).
