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

Answer 1

These functions worked for me... I got Bloodshed Dev C++;

I do remember back in the day that The turbo C++ compiler warned

you that it cannot inline the function containing loops, if statements,

select statements, and basically any type of selection or looping statements...

not an error, just a warning that your request to inline the function is DENIED...

some compilers attempt to do it, but don't say anything if they can't;

I didn't see anything regarding either function....both returned the correct

result of 6=3!

It is safe to say that Factorial() was inlined... but we aren't sure about factorial()

as it contains an if statement; no way to tell except by reverse engineering, or

getting an assembler version of the object code and check the jump and return calls

...no thanks..

================================================

using namespace std;

#include <iostream>

inline long factorial( long N)

{

long longIntNumReturn;

if (N==1)

{

longIntNumReturn=1;

}

else

{

longIntNumReturn = N * factorial(N-1);

}

return(longIntNumReturn);

}

inline long Factorial(long N)

{

return (

(

(N==1) ? 1 : (N*Factorial(N-1))

)

);

}

int main()

{

cout << factorial(3) << endl;

cout << Factorial(3) << endl;

}
