Everyone's doing it!

http://www.telegraph.co.uk/earth/environment/climatechange/7177230/New-errors-in-IPCC-climate-change-report.html

New examples of statements based on student dissertations, two of which were unpublished.

It's not like it's the first time either. Remember this one? That turned out so well in the end didn't it :icon_rolleyes:
http://en.wikipedia.org/wiki/Iraq_Dossier

that much of the work had been plagiarised from various unattributed sources.

Did I say end? Oh silly me, there will be no end to this fiasco.

What does seem to be common between them is the "sod the evidence, we know we're right because..." attitude of those publishing this propaganda.

Climate change isn't science, it's economics.
The first reason it's economics is that it's based on a whole mass of numbers(*) of dubious quality. Everybody and his dog has an opinion on what they all "might" mean, but essentially everyone is clueless in the long run.
The big advantage for CC "scientists" is that it might take 20 years before someone finally figures out that they're a charlatan. But hey, it won't matter by then, they've had one hell of a ride on the gravy train. Traditional economists are envious of this. It normally takes only a few years to discover that they've been blowing it out of their asses.

The second reason it's economics is that it gives governments an excellent "fear" stick to beat the populous with, and at the same time fleece them for more taxes.

Not to mention all the crooks moving in to …

Initiatives are things typically started by governments because they want to be seen to be doing something.

But look closely at the root "init". It's only a start; they don't have the will or interest to take it through to the end.

That's because your target OS is Win32, and absolute addresses are completely meaningless in a virtualised address space.

> I have tried using the exit() function to pass the sum back, but just keeps giving me 0 back as the exit status.
That's the result of the exec() call, not the result of the child process.

To get the result from the child, the parent uses one of the wait calls, then examines the resulting status value to get the exit status of the child.

But your spec said the child should also print things as well right?

Well you could try indenting your code.

The last return 0; seems WAY WAY out of place...

I'm shocked that someone with a programming job can't solve this trivial problem :-O

I said "close enough for you to make an attempt yourself".

Whining that the API you want doesn't exist in the form you want doesn't count. Have you studied the whole C++ bitmap API and related topics for an API which might do the same job?

This should be a minor obstacle, one that you've so far failed to show any sign of attempting yourself.

> If it is so easy - will you make translate the code to c++ for me
No.

Use a while loop to read all keys, then sleep.

> When you look at my output you can see the discrepancies start at the 50th element of the vector...
Yes, the code is still broken. You're returning a pointer to a local variable.
The result is that some of your data is trashed when that bit of the stack gets re-used for something else.

As this is C++, consider the following function prototype. void loadfile ( string filename, std::vector<double> &results );

Adding . to your PATH is a terrible idea!.

I'm joe hacker, and I've managed to create a short program called 'sl' in your world-writeable temp directory.
You lazily come along as root, and mis-spell 'ls' in an attempt to get a directory listing. You box is now mine.

Stick to ./program for running your local programs.

If you do create a program you want to keep, then create a $HOME/bin directory of your own, and put the file there. Add $HOME/bin to the end of your path, and make sure only you have access to your own bin directory.

And make sure the source for anything useful you create is safely stored somewhere :)

> This is one of those problem sets which prepares you for the job interviews.
After half a dozen clicks on that site (or should I say, "what a sight!"), it's disgusting what rubbish people spout as being good answers. There's no end of "Well my compiler does this, therefore it's the right answer".

Prepare - what a laugh.
Anyone armed with that information will either fail the interview or get confused on the first programming assignment.

The short answer is you can't, at least not in any way that is remotely useful.

For those suggesting addition, try this

#include <stdio.h>
#include <limits.h>

void f1 ( void ) {
  double a = 1E10, b = 1E-10;
  printf( "a=%.10f, b=%.10f\n", a, b );
  a = a + b;
  b = a - b;
  a = a - b;
  printf( "a=%.10f, b=%.10f\n", a, b );
  printf( "Oh dear, the tiny value got lost next to the huge value\n\n" );
}
void f2 ( void ) {
  int a = INT_MAX, b = INT_MAX - 1;
  printf( "%d %d\n", a, b );
  a = a + b;
  printf( "a is now %d - overflow\n", a );
  b = a - b;
  a = a - b;
  printf( "%d %d\n", a, b );
}

int main ( ) {
  f1();
  f2();
  return 0;
}

$ gcc foo.c
$ ./a.out 
a=10000000000.0000000000, b=0.0000000001
a=0.0000000000, b=10000000000.0000000000
Oh dear, the tiny value got lost next to the huge value

2147483647 2147483646
a is now -3 - overflow
2147483646 2147483647

And your question is what?
Did you read any of the thread, or did you just see the title and blast away?

Why would a library management project NEED a graphics header file?

And no.
It seems obvious from your question that you found your homework answer on the web, except for the fact that it has a header file you don't have.

Hence the totally weird question about looking for the same thing, without a particular header.

So do you want to learn how to program, or just pass the class?

First, INDENT your code.

main()

    int n = 0, i = 0, x = 0, ax = 0, bx = 0, cx = 0, dx = 0, ex = 0, fx =

    scanf("%s", &r);
    for (; i < 10; i++) {
        switch (r[i]) {
        case 'I':
            a[ax] = i;
            ++ax;

Your teacher is an idiot. They probably no more understand the code than you do, since all they did was grab it from the ioccc site and hand it to you.

You're NOT going to learn how to program from them. Figuring out that code will tell you NOTHING (that's NOTHING!) about how to write a C program.
Real code produced by professionals in the real world looks nothing like that kind of crap.

Feel free to direct them to this forum.

Has this so-called 'teacher' told you at any time to use any of these?
- void main
- fflush(stdin)
- conio.h
- gets(buffer)
If the answer is "all of them", then be very afraid.
I'd be worried the the answer was even any of them.

Actually, you'd probably be better off failing/dropping the class than soaking up more broken information from them.

"tomorrow" - oh the jollity.
The very idea that you could hope to learn enough to take on any random assignment like the ones you posted with only 24 hours "experience" is comical.

> guide me on how do I solve them so that I get some preparation for tomorrow
Problem solving is a skill acquired over many months and years.

This isn't the matrix, you're not going to be able to just download this and calmly announce "I know kung fu". Someone (tomorrow) will just say "show me" and you're toast.

If (and I do me IF) someone does post the answers, you're not going to get anywhere just from staring at the code. Even if you memorise it, it won't tell you anything about how to solve the next one.

Save yourself the embarrassment, and quietly drop out of the competition "for personal reasons". Anyone who is even remotely prepared for this (not you) is going to take it away.

Post #12 is as close to an answer on a plate as you're likely to get.

If you can't see the answer from there, just give up at being a C++ programmer.

> why i would come here and bother u to fix such an error!
Because that code WAS CORRECT with an OLD C++ compiler, but it is broken for a NEW C++ compiler. The link I posted (assuming that you haven't read it) explains that (and the reason why).

Your idea of "help" is something that will get you past the next assignment deadline without fixing any of the underlying problems in your knowledge.
My idea of "help" is to try to get you to work things out for yourself (with some nudging from us). But if you keep bleating "plz, it's too hard", then you're a lost cause.

> How might I began to program a text adventure/IF in Lua?
The same way you would in any other programming language.

There is so much more to writing a program than just figuring out the syntax of your current implementation language.
http://en.wikipedia.org/wiki/Software_development_process

There is no more a "how to write an adventure game" than there are "how to write a mobile phone" or "write an air traffic control system". At the fundamental level, they're all the same (except for the size of the problem).

First you figure out "what" you want.
Then you figure out "how" you're going to do it (in several iterations usually, getting more detailed each time).
Then you can start writing some code.

Once you've actually figured out the "how to program" step, then the problem and implementation are details.

Think "learning to drive". You only do this once.
Then "go fast, drive Ferrari" is one problem and implementation
and "move stuff, drive van" is another.
Sure there are a few details, and a bit of practice, but the basics should be there for either (or other) case.

> I should change it to the month it was created instead.
Is it "January"?

List of things wrong with kaveyarrasan.k's effort:
- it's two years too late
- it's in C, not C++ (see the forum title)
- it has no code tags
- it uses void main
- it has a buffer overflow (<=25 steps off the end)
- the for loop to "search" for the char to replace serves no purpose. Just use a[n] directly.
- as the input buffer is un-flushed, the %c scanf will read the \n left behind by the %d scanf earlier.

Well the Wiki link has at least one code example.
And I bet at least one of the couple of dozen links on the same page also have code as well.

Frankly, I don't think you've got the nouse to finish this assignment.
I'm finding it hard to believe you read the Wiki. More like you had a quick glance at it, then dismissed it as "useless" and posted your begging letter again.

It's your homework, make some more effort!
I'm not going to do it for you.

> please can u giv me the algorithm for the library management

int numBooksRead  = 0;
for ( i = 0 ; i < numShelves ; i++ ) {
  while ( numBooksRead == 0 );   // you are here (permanently)
}

So what do you need us for?

Presumably there are some examples you can find (if you look hard enough), which you should study, then try for yourself.

So start by doing some tests (or did you hope that you could write 500 lines and it would work first time).

Eg.

int main ( ) {
  printf( "Number of words in file=%d\n", words_in_file("test.txt") );
  return 0;
}

Keep testing that ONE function until it returns a good result for all your tests,

Then move on to the next function (which doesn't depend on other functions), say your comparisons.

Build up the picture of what works and what doesn't.

IMO, you need to put this idea on hold for 6 month and set about learning C++ from the beginning.

Sure, you might get there yourself, but every other day you'll be in some kind of hole, and on a message board asking for help on the latest problem you're faced with.
It might eventually get written, but it won't have anything to do with your skill as a programmer.

You subtract the offset from the exponent. A stored exponent of 128 say would map to a real exponent of 1. So fractions ultimately end up with negative real exponents (0.5 = 1 * 2^-1)

If you're able to extract the sign, exponent and mantissa bits, then the rest should be pretty easy. There is nothing irregular about fractions except for the magnitude of the exponent.
