...ata segment of a program and shouldn't be changed.
bar is a constant or fixed pointer to a value that can be changed. This is like a reference without the extra syntactic sugar. Because of this fact, usually you would use a reference where you would use a T* const pointer unless you need to allow N...
How can I add reflection to a C++ application?
...e it easier and cleaner to write it in the preprocessor we will use typed expression. A typed expression is just an expression that puts the type in parenthesis. So instead of writing int x you will write (int) x. Here are some handy macros to help with typed expressions:

How to add property to a class dynamically?
...
I suppose I should expand this answer, now that I'm older and wiser and know what's going on. Better late than never.
You can add a property to a class dynamically. But that's the catch: you have to add it to the class.

Switch on ranges of integers in JavaScript [duplicate]
...
Here is another way I figured it out:
const x = this.dealer;
switch (true) {
case (x < 5):
alert("less than five");
break;
case (x < 9):
alert("between 5 and 8");

Algorithm to detect intersection of two rectangles?
...
The standard method would be to do the separating axis test (do a google search on that).
In short:
Two objects don't intersect if you can find a line that separates the two objects. e.g. the objects / all points of an object are on different sides of the line.

How do you divide each element in a list by an int?
...omprehension:
myList = [10,20,30,40,50,60,70,80,90]
myInt = 10
newList = [x / myInt for x in myList]
or, if you need to maintain the reference to the original list:
myList[:] = [x / myInt for x in myList]

Split a python list into other “sublists” i.e smaller lists [duplicate]
...
I'd say
chunks = [data[x:x+100] for x in range(0, len(data), 100)]
If you are using python 2.x instead of 3.x, you can be more memory-efficient by using xrange(), changing the above code to:
chunks = [data[x:x+100] for x in xrange(0, len(data), ...
What __init__ and self do on Python?
...
In this code:
class A(object):
def __init__(self):
self.x = 'Hello'
def method_a(self, foo):
print self.x + ' ' + foo
... the self variable represents the instance of the object itself. Most object-oriented languages pass this as a hidden parameter to the methods d...
