Not quite, the ':' is the delimiter, so it should be:

Here's what I did to get your code to compile on my laptop (running hardy)


sudo apt-get install libglui-dev

I believe your first execution path is the one that gets executed. But again, why not create a temporary local-scope variable to remove all ambiguity?

I believe that what you are doing is portable. I think the scope of the tempory object is defined by the output stream's "<<" operator. If you are uncertain, why not introduce a temporary?

There is very little overhead. For example, comparing the memory usage between:



#include <unistd.h> // sleep is declared here

class AClass
{
public:
AClass(int n){

Lambda expressions are coming to C++: http://www.boost.org/doc/libs/1_39_0/doc/html/lambda.html

You will have to do something like:


template <typename T, int N>
class MyClass
{
public:
inline void method() { /* code */ };
};

I think method specializations have to be based off of the classes templated parameters (but I could be wrong). In any case, a workaround for what you want to do would be to introduce a templated...

If you haven't already, I would suggest posting your question in the programming talk forum.

For a C solution, you can check out the gnu scientific library: http://www.gnu.org/software/gsl/ (it's also in the repository)

I'm not sure what your level of knowledge is, but STL vectors incur minimal overhead over C style arrays (especially when optimizations are enabled), and the added benefits significantly outway any...

First step is to know what you need.

I would always suggest using STL vectors instead of C style arrays, so I don't know what you mean here. For an example:

Can I suggest an alternative to automake, cmake.

I'm still not understanding what you are looking for. Here is a solution for a simple linear program related to your post, written in AMPL.

I'm not exactly sure what you are asking. Are you looking for a language to model the problem in? If so, the two popular modeling languages are AMPL and GAMS. If you want to actually solve these...

You have a mis-understanding with your point 2. Passing a pointer by value will pass a copy of that pointer. The temp/copied pointer will still point to the object so usually there is no...
