   //typedef LPSTR PTSTR, LPTSTR;
    //LPTSTR -> LPSTR

    //typedef CHAR *LPSTR, *PSTR;
    //LPSTR,PSTR -> CHAR *
    LPTSTR lptStr = "Hello";

    CString csStr = "Hello";
    CString csStr1 = "HEllo";

    if(csStr == lptStr)
    {
        AfxMessageBox("csStr == lptStr");
    }

    if(csStr1 == lptStr)
    {
