<a name="idp77672648"></a><h2>Description</h2>
<p>The <a class="link" href="basic_string.html" title="Class template basic_string">basic_string</a> class represents a Sequence of characters. It contains all the usual operations of a Sequence, and, additionally, it contains standard string operations such as search and concatenation.</p>
<p>The <a class="link" href="basic_string.html" title="Class template basic_string">basic_string</a> class is parameterized by character type, and by that type's Character Traits.</p>
<p>This class has performance characteristics very much like vector<>, meaning, for example, that it does not perform reference-count or copy-on-write, and that concatenation of two strings is an O(N) operation.</p>
<p>Some of <a class="link" href="basic_string.html" title="Class template basic_string">basic_string</a>'s member functions use an unusual method of specifying positions and ranges. In addition to the conventional method using iterators, many of <a class="link" href="basic_string.html" title="Class template basic_string">basic_string</a>'s member functions use a single value pos of type size_type to represent a position (in which case the position is begin() + pos, and many of <a class="link" href="basic_string.html" title="Class template basic_string">basic_string</a>'s member functions use two values, pos and n, to represent a range. In that case pos is the beginning of the range and n is its size. That is, the range is [begin() + pos, begin() + pos + n).</p>
<p>Note that the C++ standard does not specify the complexity of <a class="link" href="basic_string.html" title="Class template basic_string">basic_string</a> operations. In this implementation, <a class="link" href="basic_string.html" title="Class template basic_string">basic_string</a> has performance characteristics very similar to those of vector: access to a single character is O(1), while copy and concatenation are O(N).</p>
<p>In this implementation, begin(), end(), rbegin(), rend(), operator[], c_str(), and data() do not invalidate iterators. In this implementation, iterators are only invalidated by member functions that explicitly change the string's contents. </p>
