在c++中，你可以做:

std::string my_str;
std::string my_str_concat = my_str + "foo";

但你不能:

std::string my_str_concat = "foo" + my_str;

操作符重载通常服从WTF。

在JavaScript中:

alert(111111111111111111111) // alerts 111111111111111110000

这对我在JSON中来回传递的一些64位键非常不利。

Forth可以随时改变数字的基数:

HEX 10 DECIMAL 16 - .
0 Ok

它也不需要是预定义的:

36 BASE ! 1Z DECIMAL .
71 Ok

Python的三元操作符

在Python中，C三元操作符(c++示例:bool isNegative = i < 0 ?True: false;)可用作语法糖:

>>> i = 1
>>> "It is positive" if i >= 0 else "It is negative!"
'It is positive'
>>> i = -1
>>> "It is positive" if i >= 0 else "It is negative!"
'It is negative!'

这并不奇怪，而是一种特征。奇怪的是，与C中的顺序(条件?答:b)。

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。

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"
}
