inline function

[vishal]

:o Actually i want to know about inline functions. the basic restrictions on them and where to use it. whether we can use return statement on it or not and the explanation about it.

I am following balagurusamy fo it and on page no. 84 of it they hav used return in inline. Also i want to know about the restrictions that why we can not use loops,switch or while in inline. And if possible pls give me some nice tutorial of friend functions
