cout << print numbers with commas

Last Modified: 2008-03-03
I would like to format the number output from cout (or printf) with commas. I have tried to use the SetLocale() to change from the standard "C" locale to several different locales but the output dosn't change. I am using VC++ 5.0.

I think you will have to rewrite the << operator
for the type of number you are talking about.

you will have to write it your self.  What you can do is format the number to a string (you can use << to send the number to a string stream)  Then count the digits and insert the commas.  I'd give you an example, but I don't have time now.

Thank you all for your responses to my question. I thought that printf would look at the settings in the "locale" struct and do formating for me, but I guess not. Oh well. Thanks again.
