Hi everybody,

I want to concatenate two wchar_t* but error.
Help me, please.

#include <iostream>
using namespace std;

int main()
{
wchar_t* name1 = L"Sơn";
wchar_t* name2 = L"Văn";
wchar_t* name3;

// I want to concatenate two name1 and name2!!!
wcscat_s(name1, 4, name2);

wprintf_s(L"%ls\n", name1);

system("pause");
return 0;
}

Thank all my friend.

Answer 3

#include <iostream>
#include <fcntl.h>
#include <io.h>
using namespace std;

int main()
{
//Changes console to UTF-16
_setmode(fileno(stdout), _O_U16TEXT);
wcout << L"\xfeff"; //Byte-order Mark

wchar_t name1[10] = L"Sơn";
wchar_t name2[] = L"Văn";
wchar_t* name3;

// I want to concatenate two name1 and name2!!!
wcsncat(name1, name2, 4);

wcout << name1 << endl;
return 0;
}
