How to copy an image using CopyFile if we know the name of the image?

Question

Programming

Hello.
How to copy an image using CopyFile if we know the name of the image?
We have an image name, there are two types (to choose from):
1. type const wchat *image_name = "001.jpg"
2. type const char *image_name2 = "001.jpg"
There is a function - CopyFile(L"\\image_name" , L"\\0\\image_name.jpg", true);
We copy the file from the root folder to folder 0, without changing the name.
It seems like a simple case, but there was a gag.
UPD:
Used wcscat. But the value p_imagedoes pc_imagenot change.
Here is the code:

WIN32_FIND_DATA FindFileData;
    HANDLE hf;
    hf = FindFirstFile(L"*.jpg", &FindFileData);
    if (hf != INVALID_HANDLE_VALUE)
    {
      do
      {
        k = 2;
        
        //CStringW image_name = FindFileData.cFileName;
        //CString myConvertedString = image_name;
        ///*const char* namefile;
        //cout << "Name file";
        //cin >> namefile;*/
        const WCHAR* image_name = FindFileData.cFileName;
        const WCHAR* image_name3 = FindFileData.cFileName;
        _bstr_t b(image_name);
        const char* image_name2 = b;

        init_image(image_name2, k, sty);
        pert1 = template_1(y, x);
        pert2 = template_2(y, x);
        pert3 = template_3(y, x);
        /*	cout << "template 1: = " << pert1 << endl;
        cout << "template 2: = " << pert2 << endl;
        cout << "template 3: = " << pert3 << endl;
        system("pause");
        */
        res = calculation_number(pert1, pert2, pert3);
        if (res == -1)
          cout << "нет распознанных цифр" << endl;
        if (res == 0)
        {
          cout << "Это изображение распознано как 0:" << image_name2 << endl;
          WCHAR *p_image = L"\\";
          WCHAR *pc_image = L"\\0\\";
          wchar_t* wcscat(wchar_t* p_image, const wchar_t* image_name3);
          wchar_t* wcscat(wchar_t* pc_image, const wchar_t* image_name3);
          wcout << p_image << endl;
          wcout << pc_image << endl;

          CopyFile(p_image, pc_image, true);
        }
          
        //std::wcout << FindFileData.cFileName << endl;
        
      } while (FindNextFile(hf, &FindFileData) != 0);
      FindClose(hf);
      system("pause");
    }
