比较2个wchar_t数组

#include<iostream>
#include <cwchar>

int main() {
    wchar_t arr1[] = L"Hello";
    wchar_t arr2[] = L"World";
    wchar_t arr3[] = L"Hello";

    if (std::wcsncmp(arr1, arr2, sizeof(arr1) / sizeof(arr1[0])) == 0) {
        std::wcout << L"arr1 and arr2 are equal"<< std::endl;
    } else {
        std::wcout << L"arr1 and arr2 are not equal"<< std::endl;
    }

    if (std::wcsncmp(arr1, arr3, sizeof(arr1) / sizeof(arr1[0])) == 0) {
        std::wcout << L"arr1 and arr3 are equal"<< std::endl;
    } else {
        std::wcout << L"arr1 and arr3 are not equal"<< std::endl;
    }

    return 0;
}
