Where you have a printf (except as a prompt), use fprintf. You will also need to open the file for writing and be sure to close it after you are done. Google got me to this URL in under 15 seconds [url]http://hackerslife.blogspot.com/2005/01/write-to-file-in-c.html[/url]

What error message?

Apparently that isn't available yet in MySql, though there is a bug about it: [url]http://bugs.mysql.com/bug.php?id=27793[/url]

Start with the Java tutorials in this forum.

I suspect you are dealing with a timing issue, where you have modules levelOne and levelTwo that each import common. After that, levelOne changes the value, but levelTwo has already got its own copy, so it doesn't see the change. If this is the problem, then the simplest solution is …

That sounds about right to me. If the program is data centered (as is probable in this environment), start with the data design, normalize the schema, and see how that affects your UML layout. Or vice versa if the program is calculation centered. Most web services deal with an MVC …

You probably don't want charAt(). If you want to extend yourself, think about doing a regular expression that matches three words, the middle one "hello" and with sub-matches for the word before and the word after. That would be maybe three lines (for that part). Start here: [url]http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/package-summary.html[/url] ... and …

If you go with the random number as a day in the year, then you can use datetime.datetime.strptime(str(number),"%j") to generate an actual date (in year 1900). The range of day number strings is "1" through "366" (though if you want to deal with leap years, you need to specify a …

I learned most of this stuff by asking questions of an expert, so don't have much experience with tutorials online. Google gives some help, of course: [LIST] [*]This one starts very far back (flat file storage), but seems to cover the bases pretty well: [url]http://www.tekstenuitleg.net/en/articles/software/database-design-tutorial/intro.html[/url] [*][url]http://www.databaseanswers.org/tutorial4_db_schema/index.htm[/url] (slide show and or …

Well, you know that sum(each visited node) == node(3,3), so you can work the problem backward: There are two legal cells adjacent to (3,3): (3,2) and (2,3). The sum just prior to reaching those cells would have to be (3,3) - (that cell). And so forth backward. You can prune …

I don't know zlib, but most compression algorithms have these properties: [LIST] [*]There is a 'lookup table' overhead, so for files that are quite short, a 'compressed file' may be longer than the raw file. The lookup table can be considered constant size (for long enough files), so other things …

The main thing is that if you want to call a function directly you have to know how to spell its name at the time when you write the code. To call a function via a pointer to it, your code can just dereference the pointer and call the result: …

It is always good to read the docs: [url]http://docs.python.org/library/internet.html[/url]

Talk to your mentor/team leader at IRDE. Tbey will either have something they want done, or at least some ideas about what is good or not so good to spend your time on.

You might want to think about some other things than just the course work and the kind of work itself. For instance: Some companies, and particularly if you work in the internal IT department, the job will be a lot of very urgent (probably small) problems that need to be …

char* is not a wide string, which is needed. There is a lot of help via google.

Short answer: "No"

A little more detail might be helpful

Also: please provide the exact input and output. As far as I can see (quickly, not carefully) there is no possible 'No added students' output.

[CODE]# put it at the end cat tomove.html >> toreceive # note >>, not >[/CODE] There are a variety of ways to put it at a particular spot in the file. You will need a temporary file to hold either the original torecieve or the new one. Lets assume you …

You appear to be translating from (postgresql?) where type text is the best option. In MySQL, varchar(size) is a better choice if possible. However, it does work, so I have not changed it. The syntax issue is the single quotes. If you want to quote table or column names, you …

What you show isn't python, I think. I think you should start with a hello world python program, in a text file, then extend it one step at a time until you get where you need to go. Working in the python line editing environment is fine for a quick …

I recommend that you use some paper or a text editor to lay out some idea of how the program should flow, ignoring coding details. After you are happy that you see how the program will flow, then start filling in code, starting with whatever part makes most sense to …

The % operator is modulo: Remainder after dividing the first operand by the second. The comments are actually helpful.

In lieu of caffeine: What change did you make to the code between compiles. Go back to the previous one and work [B]very slowly[/B] toward the next one. When the compiler doesn't return it is sometimes just working very slowly through some kind of template instantiation, and by the time …

what you need is a collection of animation coordinate arrays. The STL is your friend here: Do you want to always iterate through all the sprites? Then use a vector. Do you want to look up sprites by name? Use a map. Each Player instance then has one collection of …

As a general rule, it is better to have the database engine do as much work as possible. The engine will be able to make use of internals, hidden optimizations, etc; and you will avoid the overhead of transmitting partial results across the network to and from the db server. …

If you invoke the python interpreter from the command line, like this: [ICODE]python[/ICODE] and then type in the small program, then "no" you exit the interpreter with a control key (unix and unix-like shells, it is Ctrl-D, don't know in Windows) If, on the other hand, you put your program …

Very quickly, here's code that works for the first sentence. The others are parallel. Note that I had to fall out of regex just a little bit in order to filter out the short words.

All recursion is basically the same: Solve a big problem by splitting it into smaller problems that you solve by splitting them into smaller problems that... eventually are so small that you just do the work and return. To make it a recursive problem, the method for solving each sub …

Best solution: Create some BSTs, calculate their correct height by careful thought, test that your method gives you the expected answer. Just looking at it, I'd say your code gives you the right answer, but it works hard to do so. You might consider whether there is a way to …

You should read the 'Read me first" thread before you post here. [http://www.daniweb.com/forums/thread78060.html](http://www.daniweb.com/forums/thread78060.html) In particular, it is much easier for us to read your code if you use the CODE-tags as described in that thread.

So we have two tables that look like [CODE=sql] create some_table ( id integer not null primary key, areas_sub_local_obj integer /* etc */ ) [/CODE] where [ICODE]areas_sub_local_obj[/ICODE] is a reference to some other row in the same table. Is that right? And the merge needs to maintain the reference relationship. …

Usually, you would use either of [ICODE]'' or ""[/ICODE] (adjacent quotation marks) to show an empty trailing field. The other option is to pick a 'never otherwise used' marker and use it whenever a NULL is needed

If you want to know whether one chunk of code or another is faster you need to actually run the tests. Repeatedly and on your platform. If you do it with profiling on, you will also find out what the hot spots are so that you can optimize as needed. …

The specification of the line count is ambiguous: Does a # line increase the line count but not the character count, or is it skipped entirely. Gribouillis' code ignores the line count, but you need to deal with it one way or the other.

It looks to me as if you find the first match, but then don't look for the overlap correctly. You should actually have a state machine like this (you don't have to call it that, of course) state 0: looking for the first place it can match : string1[k] == …

For how many cases within an empty domain is any predicate true? The answer is of course zero. So depending on the quantifier of the predicate, you can predict the behavior.

There really are good reasons to prefer one language or another [B]for a particular task[/B]. There is no good way to make a general decision about what language is 'better' than another without more specification. This (I think it is silly) discussion seems to be a theme for the last …

This is a great opportunity to refactor the tables so that a student is a person and some things about being a student; a teacher is a person and some things about being a teacher. Then the select is done on the person table and your problem disappears. like: [CODE=sql] …

I think maybe Que::add is the problem: Which 'front' is the internal one? Which order should you do things in? Debugging technique: in PrintHelper, cout << 'END'<<endl if you get a null temp.
