What's the point of g++ -Wreorder?
...
Consider:
struct A {
int i;
int j;
A() : j(0), i(j) { }
};
Now i is initialized to some unknown value, not zero.
Alternatively, the initialization of i may have some side effects for which the order is important. E.g.
A(int n) : j(n++...

LPCSTR, LPCTSTR and LPTSTR
...i.e. a mutable T-string pointer, not an LPCTSTR. What you are doing is
1) convert string (a CString at a guess) into an LPCTSTR (which in practise means getting the address of its character buffer as a read-only pointer)
2) convert that read-only pointer into a writeable pointer by casting away it...
Omitting all xsi and xsd namespaces when serializing an object in .NET?
... I would just like to add that removing the default namespace can have unintended consequences : for instance, if you use the XmlInclude attribute to serialize derived types, the namespaces will be added to each of these elements, whether you want it or not, because they're necessary for deseriali...
How do I determine whether an array contains a particular value in Java?
...rrays.stream(values).anyMatch("s"::equals);
To check whether an array of int, double or long contains a value use IntStream, DoubleStream or LongStream respectively.
Example
int[] a = {1,2,3,4};
boolean contains = IntStream.of(a).anyMatch(x -> x == 4);

When would you use a List instead of a Dictionary?

When you don't need fast lookups on key - maintaining the hashtable used by Dictionary has a certain overhead.

What is the difference between class and instance methods?
... used with just the class name. In Objective-C they are defined thusly:
@interface MyClass : NSObject
+ (void)aClassMethod;
- (void)anInstanceMethod;
@end
They could then be used like so:
[MyClass aClassMethod];
MyClass *object = [[MyClass alloc] init];
[object anInstanceMethod];
Some real...
How do I trim leading/trailing whitespace in a standard way?

If you can modify the string:
// Note: This function returns a pointer to a substring of the original string.
// If the given string was allocated dynamically, the caller must not overwrite
// that pointer with the returned value, since the original pointer must be
// deallocated using the...
Setting unique Constraint with fluent API?

Extending from two classes
...
You can only Extend a single class. And implement Interfaces from many sources.
Extending multiple classes is not available. The only solution I can think of is not inheriting either class but instead having an internal variable of each class and doing more of a proxy by r...
