What does “static” mean in C?
...call stack.
And to answer your second question, it's not like in C#.
In C++, however, static is also used to define class attributes (shared between all objects of the same class) and methods. In C there are no classes, so this feature is irrelevant.

How to unit test an object with database queries
...place, we were then able to do something like this in our code (we work in C++, but I'm sure you get the idea):
GetDatabase().ExecuteSQL( "INSERT INTO foo ( blah, blah )" )
At normal run time, GetDatabase() would return an object that fed all our sql (including queries), via ODBC directly to the d...
Which is the fastest algorithm to find prime numbers?
Which is the fastest algorithm to find out prime numbers using C++? I have used sieve's algorithm but I still want it to be faster!

What is the difference between JavaScript and ECMAScript?
...nguage? The standard defines the language. If some language implements the C++ standard, it is called C++, not something else (exactly because it implements that standard). So I still have the same question... what's the difference?

Can we write our own iterator in Java?
.../ creating an array of Strings
String[] languages = new String[]{"C", "C++", "Java", "Python", "Scala"};
// create your list and hold the values using the same list implementation.
SOList<String> languagesList = new SOList<String>(languages);
System.out.println("");

Should I prefer pointers or references in member data?
...re's no way to factor out this initialisation into another function (until C++0x, anyway edit: C++ now has delegating constructors)
the reference cannot be rebound or be null. This can be an advantage, but if the code ever needs changing to allow rebinding or for the member to be null, all uses of t...
What is a race condition?
...olution is: you lock the tickets between 4-5 with mutex (mutual exception, c++). In real world it is called ticket reservation :)

How does Dijkstra's Algorithm and A-Star compare?
...ause it uses less memory.
The code for Dijkstra's algorithm is:
// A C / C++ program for Dijkstra's single source shortest path algorithm.
// The program is for adjacency matrix representation of the graph
#include <stdio.h>
#include <limits.h>
// Number of vertices in the graph
