**Affected subclause:** [[basic.string]](basic.string)  


**Change:** Non-const .data() member added[.](#1.sentence-1)

  


**Rationale:** The lack of a non-const .data() differed from the similar member of std​::​vector[.](#1.sentence-2)

This change regularizes behavior[.](#1.sentence-3)

  


**Effect on original feature:** Overloaded functions which have differing code paths
for char* and const char* arguments
will execute differently
when called with a non-const string's .data() member
in this revision of C++[.](#1.sentence-4)

[*Example [1](#example-1)*: int f(char *) = delete;int f(const char *);
string s;int x = f(s.data()); // ill-formed; previously well-formed — *end example*]
