C++ TCHAR to char conversion

Question

How do you convert a TCHAR to a char array without using built-in functions and with out including other header files (how do you do convert TCHAR to char using standard c++ )

int main()
{

    TCHAR szProcessName[MAX_PATH] = _T("<unknown>");
    char szText[MAX_PATH] ;

    std::cout << sizeof(szProcessName)/sizeof(TCHAR) << std::endl;


    for (int i =0; i <sizeof(szProcessName)/sizeof(TCHAR); i++ )
    {
            szText[i] = (char)szProcessName[i];
    }
    //szText[sizeof(szProcessName)/sizeof(TCHAR)] = '\0';

    std::cout << strlen(szText) << " " << strlen("<unknown>") <<std::endl;
    std::cout << szText <<  " <unknown>" <<std::endl;


    if (szText == "<unknown>") 
        std::cout << "equal" << std::endl;
    else 
        std::cout << "Not equal " << std::endl;


    return 0; 
}

what i got in the console

$ g++ test.cpp && ./a.exe
260
9 9
<unknown> <unknown>
Not equal

Answer 1

I wrote my own function to compare two char arrays

int cmpstrs( char *x , char* y )
{

    if (strlen(x) != strlen(y) )
        return 0;

    for (int i =0; i < strlen(x); i++ )
    {
        if (x[i] != y[i])
            return 0;
    }   
    return 1;

}
