Summary

Section 21.1 Introduction

• Class template basic_string provides typical string-manipulation operations.

• The typedef statement

  
  typedef basic_string< char > string;
  

  creates the alias type string for basic_string<char> (p. 870). A typedef also is provided for the wchar_t type (wstring).

• To use strings, include C++ Standard Library header <string>.

• Assigning a single character to a string object is permitted in an assignment statement.

• strings are not necessarily null terminated.

• Most string member functions take as arguments a starting subscript location and the number of characters on which to operate.

• string member functions size and length (p. 871) return the number of characters currently stored in a string.
