我最喜欢的奇怪的C语言是5[“Hello World”]，但因为已经发布了，我最喜欢的第二个奇怪的是Windows版本结构初始化黑客:

void someWindowsFunction() {
    BITMAPINFOHEADER header = {sizeof header};

    /* do stuff with header */
}

这条微妙的线条达到了以下效果:

Declares a BITMAPINFOHEADER structure Concisely sets the "size" member of the structure, without hardcoding a size constant (since many Window structures, including BITMAPINFOHEADER, follow the convention of specifying the size of the structure as the first member} Declares the version of the structure (since many Windows structures, including BITMAPINFOHEADER, identify their version by the declared size, following the convention that structures definitions are append-only) Clears all other members of the structure (a C standard behavior when a structure is incompletely initialized).

c++(或Java)中没有封装的事实。任何对象都可以违反任何其他对象的封装，破坏它的私有数据，只要它是相同的类型。例如:

#include <iostream>
using namespace std;

class X
{
  public:
    // Construct by passing internal value
    X (int i) : i (i) {}

    // This breaks encapsulation
    void violate (X & other)
    {
        other.i += i;
    }

    int get () { return i; }

  private:
    int i;
};

int main (int ac, char * av[])
{
    X a(1), b(2), c(3);

    a.violate (c);
    b.violate (c);
    cout << c.get() << endl;    // "6"
}

APL(除了ALL)，在一行中编写任何程序的能力。

代码由作者在http://mysite.verizon.net/les.peters/id2.html详细解释

Delphi不关心像“word”这样的类型转换，将读取数组arr[0..65535] where pos = 65535: Arr[单词(pos + 10)]

在C语言中，数组可以像这样被索引:

a[10]

这很常见。

然而，鲜为人知的形式(真正有效!)是:

10[a]

这与上面的意思相同。
