C和c++中的三联体。

int main() {
   printf("LOL??!");
}

这将打印LOL|，因为trigraph ??!转换为|。

在Ruby中，0在条件表达式中求值为true。

通知7。一个有效程序的例子:

    Chomsky is a room. 
    A thought is a kind of thing. 
    Color is a kind of value. 
    The colors are red, green and blue. 
    A thought has a color. It is usually Green. 
    A thought can be colorful or colorless. It is usually colorless. 
    An idea is a thought in Chomsky with description "Colorless green ideas sleep furiously." 
    A manner is a kind of thing. 
    Furiously is a manner. 
    Sleeping relates one thought to one manner. 
    The verb to sleep (he sleeps, they sleep, he slept, it is slept, he is sleeping) implies the sleeping relation. 
    Colorless green ideas sleep furiously. 

像图灵机模拟器这样的其他愚蠢的东西可以找到。

我有点纠结:

1;

在perl中，模块需要返回true。

在awk中，数组从索引1开始，这是最不容易混淆的。

在我看来，在c#中能够将超出范围的整数转换为枚举是非常奇怪的。想象一下这个枚举:

enum Colour
{
    Red = 1,
    Green = 2,
    Blue = 3
}

现在，如果你写:

Colour eco;
eco = (Colour)17;

编译器认为这很好。还有运行时。
