# std::wcscat

From cppreference.com
< cpp‎ | string‎ | wide

Defined in header `<cwchar>` |  |
wchar_t *wcscat( wchar_t *dest, const wchar_t *src ); |  |

Appends a copy of the wide string pointed to by `src` to the end of the wide string pointed to by `dest`. The wide character `src[0]` replaces the null terminator at the end of `dest`. The resulting wide string is null-terminated.

The behavior is undefined if the destination array is not large enough for the contents of both `str` and `dest` and the terminating null wide character.

The behavior is undefined if the strings overlap.

### Parameters

dest | - | pointer to the null-terminated wide string to append to
src | - | pointer to the null-terminated wide string to copy from

### Return value

Returns a copy of `dest`

### Example

Run this code

    #include <iostream>
    #include <cwchar>
    #include <clocale>

    int main(void)
    {
        wchar_t str[50] = L"Земля, прощай.";
        std::wcscat(str, L" ");
        std::wcscat(str, L"В добрый путь.");

        std::setlocale(LC_ALL, "en_US.utf8");
        std::wcout.imbue(std::locale("en_US.utf8"));
        std::wcout << str << '\n';
    }

Possible output:

    Земля, прощай. В добрый путь.
