Why can't C++ be parsed with a LR(1) parser?
...xed as:
int (MyClass::*)(char*) MethodPtr;
this being coherent with the cast operator (int (MyClass::*)(char*))
typedef int type, *type_ptr; could be forbidden too : one line per typedef. Thus it would become
typedef int type;
typedef int *type_ptr;
sizeof int, sizeof char, sizeof long lon...
C/C++ with GCC: Statically add resource files to executable/library
...t uniform, then char is probably the most convenient: take its address and cast the pointer to the proper type as you traverse the data.

问题的提出申请过那么多的微博，数申请网易微博的动机最不纯，因为它的字数限制不是传说中的140字，而是163个字。当年觉得很可爱，于是就注册了，之后再也没登录过。今天在人人网转发状态，提示我超过140字了，突然就好...
Copy constructor versus Clone()
... used. It also returns object, which is a pain, since it requires a lot of casting. (And though you specifically mentioned classes in the question, implementing ICloneable on a struct requires boxing.)
A copy constuctor also suffers from one of the problems with ICloneable. It isn't obvious whether...
Best way to compare two complex objects
....Equals method (whose execution would be marginally slower due to the type cast).
When you override Object.Equals, you’re also expected to override Object.GetHashCode; I didn’t do so below for the sake of conciseness.

PreparedStatement IN clause alternatives?
...statement is ... IN (SELECT UNNEST(?::VARCHAR[])) or ... IN (SELECT UNNEST(CAST(? AS VARCHAR[]))). (PS: I don't think ANY works with a SELECT.)

What is the equivalent of the C# 'var' keyword in Java?

I can't imagine a real world scenario where this is indicative of good design, but this may not work as you expect:
class Foo {
public void Non() {}
public virtual void Virt() {}
}
class Bar : Foo {
