Is it possible to have a recursive inline function in C++?

Question

1)I have an inline function with recursion, when i compiled it i am not seeing any Error/Warning for that why?
2)As far as i know its compiler dependent whether to copy inline function or not, but my question is how we will get to know whether compiler has added inline function or not?
3)In What stage of compilation Inline function will be copied?

Answer 1

Yes it is possible to have a recursive inline function in C++, see the following sample code -

inline int factorial(int num)
{
    if(!num)
    {
       return 1;
    }
    else
    {
       return num*factorial(num-1);
    }
}
