convert char to wchar

[ekailan]

This is a test code to convert chat to wchar the problem is that each time the else statement is executed .....So the conversion is not working !!!!!!!

char p[500];
 while(getline(inFile1, line))
  {     
    //we read p from file that contain only one word "why"............for testing
    strcpy_s(p, 500, line.c_str());
 
    string search = p;
    const size_t newsize = 100;
    size_t origsize = strlen(search.c_str()) + 1;
    size_t convertedChars = 0;
    wchar_t wcstring[newsize];
    mbstowcs( wcstring, search.c_str(), newsize);
    wcscat_s(wcstring, L" (wchar_t *)");
 
    if(wcstring == L"why")
            cout<<"Right conversion";
            else
            cout<<"Wrong conversion";

if(wcstring == L"why")

This is always false.

wcstring is an array of wchar_t. Therefore, the name wcstring is the address of element 0. Ditto for L"why". That's the address of the "w".

Since there are two arrays the addresses will always be different.

I suggest you use wcscmp, or if you use the == operator, do so with two wstring objects.
