How to convert an enum type variable to a string?
... help of the Boost.Preprocessor library, which can be used with both C and C++ code, you can easily take advantage of the preprocessor and let it generate this function for you. The generation macro is as follows:
#include <boost/preprocessor.hpp>
#define X_DEFINE_ENUM_WITH_STRING_CONVERSIO...
How do I detect unsigned integer multiply overflow?
I was writing a program in C++ to find all solutions of a b = c , where a , b and c together use all the digits 0-9 exactly once. The program looped over values of a and b , and it ran a digit-counting routine each time on a , b and ab to check if the digits condition was satisfied.

When to use “new” and when not to, in C++? [duplicate]
When should I use the "new" operator in C++? I'm coming from C#/Java background and instantiating objects is confusing for me.

C++11 std::threads vs posix threads
...her abstraction level, a really good interface and plays nicely with other C++11 classes.
The C++11 std::thread class unfortunately doesn't work reliably (yet) on every platform, even if C++11 seems available. For instance in native Android std::thread or Win64 it just does not work or has severe p...
Why don't structs support inheritance?
... "inline storage" behavior of arrays, Bad Things happen, as can be seen in C++.
Consider this pseudo-C# code:
struct Base
{
public int A;
}
struct Derived : Base
{
public int B;
}
void Square(Base[] values)
{
for (int i = 0; i < values.Length; ++i)
values [i].A *= 2;
}

How can I reliably get an object's address when operator& is overloaded?
...
Update: in C++11, one may use std::addressof instead of boost::addressof.
Let us first copy the code from Boost, minus the compiler work around bits:
template<class T>
struct addr_impl_ref
{
T & v_;
inline addr_impl_r...

Are static class variables possible in Python?
...4
>>> MyClass.i, m.i
>>> (3, 4)
This is different from C++ and Java, but not so different from C#, where a static member can't be accessed using a reference to an instance.
See what the Python tutorial has to say on the subject of classes and class objects.
