wstring
Declares a string of wide characters. wstring is a typedef that specializes the template class basic_string to contain wchar_t string data. wstring inherits the capabilities of the basic_string class; this includes operators and methods.
Other typedefs that specialize basic_string include string, u16string, and u32string. For more information, see <string> Members.
typedef basic_string<wchar_t, char_traits<wchar_t>, allocator<wchar_t> > wstring;
Example
// string_wstring.cpp
// compile with: /EHsc
#include <string>
#include <iostream>
int main( )
{
using namespace std;
// Equivalent ways to declare an object of type
// basic_string <wchar_t>
const basic_string <wchar_t> s1 ( L"abc" );
wstring s2 ( L"abc" ); // Uses the typedef for wstring
// Comparison between two objects of type basic_string <wchar_t>
if ( s1 == s2 )
cout << "The strings s1 & s2 are equal." << endl;
else
cout << "The strings s1 & s2 are not equal." << endl;
}
The strings s1 & s2 are equal.
