got 45 on linux
than tried with fflush(stdout) and got 9 which is correct . so I guess that
both child and parent process getting the same buffer and thus resulting in
more number of hello

correct answer is 9 as already mentioned

Output Hello printed 10 times. Since form command spawns the process, so for
every call their are two process created and since if process gets
successfully created fork returns some positive no. which is the process id,
so it will break the loop and finally only the 10 child processes will be
left which will print Hello 10 times. I hope that I cleared your doubt.

 can u plz explain how 10 processes are created..? shouldn't it be 9..??

 On Thu, Sep 22, 2011 at 12:23 AM, ravi maggon maggonr...@gmail.comwrote:

 Output Hello printed 10 times. Since form command spawns the process,
 so for every call their are two process created and since if process gets
 successfully created fork returns some positive no. which is the process 
 id,
 so it will break the loop and finally only the 10 child processes will be
 left which will print Hello 10 times. I hope that I cleared your doubt.

Re: [algogeeks] plz help

2011-09-07 Thread rahul vatsa
i think it should be 1.
5/2 paintings r made by 5/2 ppl in 5/2 days  using 5/2 canvas
= 1 painting is made by 1 person in 1 day using 1 canvas

i.e. 1 guy cn make a painting in 1 day using a canvas.

Now, the other case, to make 25 paintings using 25 canvases in 25 days.

As there r 25 days  total paintings required is 25, so u need just 1 guy to
do that. u have here 25 canvases, bt he cn make using just 1.

I think the code is running infinity times as there is no checking condition
when to stop the calculation of max value. so before going to the max
function there should be a checking till when you need to run the loop.

Well This is Certainly lacks logic behind the Coder.

Please remember EVERY RECURSIVE PROGRAM Need Break for certain condition.

here mid keep updating without knowing when to finish the recursion so the
code never goes below line seven..


I appreciate this way of Creating LOOP although its a good CPU hogging
program..


Keep Working... :P
