But is the Coordinater definition known to CPF_Thread when it is defined? The cpf_thread.h file should look something like this,
#include "Coordinater.h"
class CPF_Thread
{
// ....
};

Thank you, you are as just as they come.

Could you please be more specfic.
What is this feature of Python you are looking for in C++?
I can tell you right now that if you give up information there is no way of getting it back unless...

In an educational situation "working" may not be good enougth. Maybe the code should be of a certain quality reflecting what you have been taught.
Why not ask the teacher to be more specific...

Well, an include guard will take care of the linker problem.
Regarding many types in a vector I strongly advice you to seek a solution that avoids downcasting. The most common way is to declare...
-
You can store any pointer data type already in a vector since you can upcast any pointer to void*. And you can always downcast a void* pointer again to its actual type although this will not be...

It appears to have been submitted already,

You need to add an include guard. Otherwise the compiler will generate a function in each compilation unit. The linker will then find several versions of the same function.
One way (if you use...

Dear quorsum,
On behalf of the rest of us I would like to extend an appology. Despite our sincere efforts our replies must have blocked your thinking and so of course we don't deserve even a thank...

Well, the OP wanted equivalence and returning f is closer to the original.
I agree it may be safer to rule out NaN first and since the order doesn't matter logically I change my suggestion...

The Java function can be used pretty much as written. Here's a C++ 11 template version to handle both float and double:
#include <cmath>
template<typename T>
T signum(T f) {
return...
-
I think "return 0.0;" should rather be "return f;" to conform with the original.
But std::isnan in <cmath> is overloaded both for float and double.
Why is that? For an || logical...

Only you know since you're not telling how you compare.
Have you printed what file_name points at so you know it is '\0' indeed?
Are you sure you are comparing what file_name points at and not...

The STL containers don't give you access to implementation detail like say internal pointers.
What you could do is push the elements on stack, clear the list, and then rebuild it with the elements...

Locality? It beats me why you consider this,
void foo() {
auto unitColors_at_or_zero = [&]( auto id ){ auto it = unitColors.find(id); return it != unitColors.end() ? *it : 0; };
DWORD...

That works for me too. :)
But there's a certain amount of implementation dependency at play here and it's never wrong to be explicit about the literal type.
Also it seems in C++ 11 it's...
-
You don't have to do anything special. You can treat it like you would an int or double.
-
To denote a long long literal you need to add one of the suffixes l or L like
long long test = 5000000000L;
-
That's typical feature overuse. Something a pumped up newbie would put in to show off. You get the worst of two worlds:
As implementation it's too much. What's wrong with a simple free function? ...
-
Certainly (as all replies show) but regardless of how you decide to do it I suggest you encapsulate the map, the initialization of the map and accesses to the map in a class called say UnitColors...

As an abstract data type a heap is called a priority queue so that's what you should be looking for.
The C++ standard library has one called std:: priority_queue and I'm quite certain there is one...

Recursive problem formulations are often succinct and elegant but they have their fair share of problems in practice. One is the risk of running out of stack space, another is the relative slowness...
-
Well, my intention was just to clarify the recursive solution in principle.
Optimization is another story.
The dictionary strategy they suggested probably was a memoization attempt to avoid...
-
That is a recursive formulation of the problem. In code it would look like this,
int count(int a, int b) {
if (a>b) return 0; // no solution
else if (a==b) return 1; // one solution

If you plan to return a pointer to the 2D array you are asking for trouble. Chances are it gets stale and there will be a much harder to find runtime bug.
The most immediate solution is to return...
