is there a ...

tool that you can trace a recursive function?
or in other words a tool, program, etc, where graphicaly you can see the workflow of recursion? have somebody a link for this great tool(if exists).
or give me some tips how can i follow a recursive function steps

thanks in advance

You could have the program generate a file and output information during every step of the recursive function to said file.

ok i know i have a lot of options to trace that, but i just was curious if there exists some kind of tool to see recursion in action,
thanks for posting

A good visual debugger will allow you to unwind and inspect the call stack.

If you want some kind of visual feed back as your code recurses, you will have to do that your self :)

Well you could take CInt which is a C/C++ interpreter and modify it to show you the steps the function is going through. It may even have the ability already built in.

Edit: 100th post.:D

ok thanks for reply

i will have to make that kind of tool, and maybe could be helpfull
for other people learning to program, specialy to show the real power of recursion, and how it works.

i'm thinking of a tool that you enter some options , functions, etc
and that show you visualy(grapchics) how it will behave.
of course that will be when i finish my c++ book.

i would like to help you with recurrsion.. but i am still in the process of learning recurssion. :D

I would assume a profiler might be able to help you with this, but I've never used one for that purpose.

:p well i understand recursion , know i'm learning data structures(binary trees) and im using recursion a lot, but sometimes i get lost where the execution of the program goes :D

recursion is simple. it's just when a program calls itself. or you could do something weird like:

Code:

---

int recur(int i)
{
  cout<<i<<endl;
  return recur(i/2);
}

---

a fractal generator ;)

i think after learning recurrsion.. i might move on to recurrsion.. and then maybe after that study a little on recurrsion

maybe learning how to spell it would get rid of that infinite recursion problem ;)

>is there a ... tool that you can trace a recursive function?
cout.

>but sometimes i get lost where the execution of the program goes
Print it as it goes, litter your code with print statements, and draw the structure on paper. Paper is very important when working with complex data structures. Most of the time you simply cannot get everything in your head and paper is a good place to put down what you know as well as what you expect so that you can compare with what is. :)

best advice ever... I used to think I could do it all in my head, but after learning inheritance and polymorphism and using them in loops nested to the level of 5 along with recursive functions, you really lose your way... then you change one little think and if fcks with your entire program...
