What is tail call optimization?

Question

Very simply, what is tail-call optimization?

More specifically, what are some small code snippets where it could be applied, and where not, with an explanation of wh

Answer 1

1. We should ensure that there are no goto statements in the function itself .. taken care by function call being the last thing in the callee function.

2. Large scale recursions can use this for optimizations, but in small scale, the instruction overhead for making the function call a tail call reduces the actual purpose.

3. TCO might cause a forever running function:

   void eternity()
   {
       eternity();
   }
