c++ char* 与LPCTSTR相互转化

char ch[1024] = "wo shi ni baba";
    int num = MultiByteToWideChar(0, 0, ch, -1, NULL, 0);
    wchar_t *wide = new wchar_t[num];
    MultiByteToWideChar(0, 0, ch, -1, wide, num);
    //查看转换好的结果
    cout << wide[3] << endl;

    
    //LPCTSTR 转换成 char *
    wchar_t widestr[1024] = L"wo shi ni yeye";
    int num1 = WideCharToMultiByte(CP_OEMCP, NULL, widestr, -1, NULL, 0, NULL, FALSE);
    char *pchar = new char[num1];
    WideCharToMultiByte(CP_OEMCP, NULL, widestr, -1, pchar, num1, NULL, FALSE);
    //查看转换好的结果
    cout << pchar[1] << endl;
