How to use stoull on VS2008?

Question

Do you have any idea on how to use stoull on Visual Studio 2008? I want to convert string to unsigned long long. Thanks!

http://msdn.microsoft.com/en-us/library/ee404774.aspx - if you click on "other versions", it shows that it isn't available before 2010. Try using `stringstream` instead? — Mats Petersson, Jul 24 '13 at 00:16
@chris Is there any way I can implement `stoull` or any other method that I can use to achieve unsigned long long? — Christian Mark Ramos Godoy, Jul 24 '13 at 00:17
@ChristianMarkRamosGodoy, `long long` wasn't a standard type before C++11, so I'm not completely sure. — chris, Jul 24 '13 at 00:18
@ChristianMarkRamosGodoy As was pointed out to you by [an answer](http://stackoverflow.com/a/17814627/583833) in your other question, you can use stringstreams for this. — Borgleader, Jul 24 '13 at 00:25
In VC2008 and earier, you can use a (non-standard) `_strtoui64`; [see documentation](http://msdn.microsoft.com/en-us/library/85zk715d.aspx). `__int64` is the same type as `long long` with these compilers. — Igor Tandetnik, Jul 24 '13 at 04:32

you can make use of : _atoi64, _atoi64_l, _wtoi64, _wtoi64_l which converts a string to a 64-bit integer.

hope this helps!! Happy coding, -codevik
