AND print the formatted output directly

But I a little bit curious about the fast I/O... I always use gets to make my solution faster... but it was "less" faster than I thought... So, can someone give me an example how to make fast I/O parser? Thanks.

ID = (number of pancakes) - ID
And I got AC..

If I simulate like these: 8 4 6 7 5 2 -> 6 2 5 7 6 4 8 -> 3 7 5 2 6 4 8 -> 5 4 6 2 5 7 8 -> 2 6 4 2 5 7 8 -> 4 5 2 4 6 7 8 -> 3 4 2 5 6 7 8 -> 2 2 4 5 6 7 8 -> 0 5 1 2 3 4 -> 5 4 3 2 1 5 -> 4 1 2 3 4 5 -> 0 Does the algorithm correct? I just want to clarify if my approach is correct.

Strange Result on Struct

My friend of mine ask me about this code and I was unable to answer it why. Here's the code: #include<stdio.h> struct da{ int a; short b; }asd; void main(){ printf("%d",sizeof(asd)); } It supposed to be 6 bytes, didn't it? But when my friend compiled it with GCC and VC++ 6, he got 8 bytes?...

Maybe, with files, it's easier to understand: #include <iostream> #include <fstream> using namespace std; int main() { ofstream outfile("__test__.txt"); outfile << "You will not see this string till outfile.flush() is run."; cin.get(); // open __test__.txt to check if it contain...

#include <iostream> using namespace std; int main(){ cout << "a" << flush; while(1){} } But now it does make a difference, doesn't it? You should use flush only when you know what you're doing, in very few and specific situations (for instance when you're dealing with pipes). Confused... ...

I still don't get it... from http://www.cs.hmc.edu/~geoff/classes/hmc.cs070.200401/notes/io.html and http://www.gillius.org/ctut/app_b.htm it explain that flush usage is to output the buffer... but, when I try with these code: #include <iostream.h> int main() { char mystrin[10] = "HELLO"; ...

flush

I just don't understand, what flush() means in C++? I mean flush with cout object, like this:

Code: Select all

``````...
cout.flush();
...``````
Is there also for cin object? Thanx...

Hmmm... still confused why... from your given code (I've compiled it with MS Visual with some modification on codes) I have not seen the modified code -- so can't comment. Also, VC++ 6 is not something I am very familiar with, so it would be unwise to give you misleading info. But there were a few ...

Thanx Sumankar for your explanation... Because there is no object of type inner created when an object of type OuterBar is created.Forget the virtual stuff. OuterBar is derived from Outer (and both ctors are being called).The base class has declared a nested class but does not have a member object o...

Re: Code (don't understand)

class Outer { protected: T Inner; }; How would you read this for some type T? Think about access qualifiers. I have't come across anything that says it should be anything else when it comes to a nested class. I might be wrong ;) so prove me wrong. Also, the forget the `virtual' in the next part and...
