No more with a signed integer than with an unsigned. What's your point?
Like I said, I tried this for a while and stopped, because I realized I was over-complicating my code.
With an unsigned...

Obviously. My point is that "the value should never be negative" is not a reason to use an unsigned type. There may still be situations where you need to take a difference or use the value in an...

What would you gain from making the function static? It only requires more typing.
February 26th, 2015, 02:17 AM
I would strongly advice against mixing signed and unsigned integers. Just take this simple example:
int numerator = -1;
unsigned int denominator = 2;
bool isNegative = (numerator * denominator...

You start by writing all the tests (in this case unit tests) and then implement your class function by function to pass all the tests. This forces you to first think about all the functionality your...

Better to use a bool for the sign (and name it something like isPositive or isNegative), since there can only be two possible states ever.
Your setnumerator and setdenominator functions violate...

Don't use new  in C++, there is no need for it. Use std::vector instead.
And please post the code here, rather than providing some external link.
What do you mean by "doesn't work"?

That's not really a solution. How will this code be able to create/copy/destroy an instance of X?
Why do you want to get rid of the class template? What do you want to accomplish at a...

Not exactly. It's not throwing the exception during stack unwinding that is the problem. The problem is when the exception thrown during stack unwinding is not caught. If you catch any thrown...

Don't know if threads are covered in the book, but a quick way to make the program update approximately each second is to run the loop in a thread.

Well, no, because Windows Forms requires .Net and unmanaged C++ doesn't give you that.
What do you miss?
If you mean a nice looking GUI application, then yes that's possible in C++.

Calling sleep pretty much puts your program (well, the thread that calls sleep) into a coma. It doesn't do anything until it wakes from its sleep. One important thing your program won't do while it...

Why not just send the dialog a custom message to tell it to update the combo box contents? Or just add a member function to the dialog class that you call directly?

You call a dictionary application a text predictor and then conclude from that example that a dictionary is a form of text predictor. Seems like circular reasoning to me.
I would assume the...

When you say 'hashtable size' do you mean 'number of buckets'?
I think OP meant not knowing the maximum number of data elements to be stored ahead of time.
What makes you say this is a bad idea?...

Are you benchmarking unoptimized code? That's not very useful.
July 23rd, 2014, 08:31 AM
This might be a (premature) optimization trick to prevent branching due to the short-circuiting behavior of &&.
Look how much easier to read your code becomes with a few local variables. You should really stop copy-pasting source code; it's a very bad habit.
Yes, you could do that. but it sounds to me like a list box is better suited for your user interface. This would also allow the user to select an item by typing multiple characters, which is much...

I'm sure you can come up with a test case that fails the second algorithm.
As to why the first one may be too slow: a std::set keeps all its elements sorted. Dijkstra's algorithm only needs to...
That's basically the algorithm for finding a topological order. ;)
That's because there is no specialization for 'implements_load' and 'implements_store'. Don't know if you removed this to get a minimal example or if they are missing in your actual code (maybe the...
Compiles fine in VC9.
What is the complete error message you get?
