CString question

[benjnp]

here's a sample line of codes #1 CString strLine; strLine = "Hello"; cout << strLine << endl; output 007706BC #2 CString strLine; strLine = "Hello"; printf("%s\n", strLine); output Hello Why didn't cout display the "Hello" string, but using printf will display the desired output. What's the difference between cout and printf that made the above discrepancy? Thanx :)

Try using String of char* instead of CString. Just remember to import in your C++ file.

CString has the address of the memory location I think.

take a look at this http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcmfc98/html/_mfc_cstring.3a3a.operator_lpctstr.asp i think u should cast it to (LPCTSTR) cout << (LPCTSTR) Your_CString_Object;

Use GetBuffer to the underlying char *, don't forget to call ReleaseBuffer after. Christian Graus - Microsoft MVP - C++

Thanx guys, Now I know what's the difference and what to do. But since it is a console app, i'll use printf instead. :)

yup, both cout and printf can be used in console applications but since cout had some trouble or need additional things to consider, I think it will be beneficial to use printf instead

It was doing exactly what it was told to do. benjnp wrote: I think it will be beneficial to use printf instead If you consider the lack of about nine characters to be beneficial, you've a great deal to learn. It would be beneficlal to learn how a CString object behaves when used with cout and printf(). You'll be amazed at what you find!

Got your point. I understood how a CString object works especially when used in cout. But for now, since I'm in a hurry, I'll use printf for the moment.
