can anybody tell me how this code works
-
int compute(int n) { if(n>0) { n=compute(n-3)+compute(n-1) return n; } return 1; } void main() { x=compute(5); cout<<x; } o/p:9 can anybody explain in detail the flow
It won't until you fix at least two syntax errors. :rolleyes:

I can tell you why it doesn't work: it goes into infinite recursion. I was wrong. :)

While I don't know exactly what it computes, it does indeed terminate.

1/ Fire up visual studio. 2/ Compile your program. 3/ set a breakpoint in main. 4/ Assuming VS6, press f11 to step into compute. put n in your watch window. 5/ press f11 a lot, until the program is finished. 6/ Enjoy your new shiny enlightenment. Fight evil monks on bleak mountains. Iain.
Plz sir... CPallini CPallini abuz drugz, plz plz help urgent.
that the right way to debug a program :)

Nah! I said that because the OP seems to be *wondering* how it works. That code should work, BTW [insert very much unsure smiley here]. I don't have a compiler here though.
