explode(): Returns an array of strings, each of which is a substring of

Choosing which C++ Container to use can be tricky, so here's a simple flowchart to help decide which Container is right for the job.
This flowchart was based on Mikael Persson's post.
This little graphic in the flowchart is from Megan Hopkins
Static members have class scope as opposed to object scope
C++ Example
// define in header
class Singleton {
public:
static Singleton *getInstance();
private:
Singleton() {}
static Singleton *instance;
};
// initialize in .cpp
Singleton* Singleton::instance = 0...
Defined within Another Class
C++
Nested Class[ref] (needs a reference to enclosing class)
class Outer {
class Inner {
public:
Inner(Outer* o) :outer(o) {}
private:
Outer* outer;
};
};
Java
[non-static] Nested Class (aka Inner Class or Member Class...
Many argue that Java is ONLY pass-by-value, but it's more nuanced than that.
Compare the following C++ and Java examples to see the many flavors of pass-by-value (aka copy) and pass-by-reference (aka alias).
C++ Example (complete code)
// passes a COPY of the object
static void passByCopy(Pa...
