变量和函数的名字就用来对应表中的key部分,value部分包含一系列信息,例如变量的类型,所占据的字节长度,或是函数的返回值。 在链接进行之前,部分符号是 undefined 的,也就是编译器此时还不知道这部分符号对应的代码的具体位置。 链接 由汇编程序生成的目标文件并不能立即就被执行,其中可能还有许多没有解决的问题。例如...

keeps an array of integer objects for all integers between -5 and 256, when you create an int in that range you actually just get back a reference to the existing object. So it should be possible to change the value of 1. I suspect the behaviour of Python in this case is undefined....
另外,它的双等号“==”除了有基本的比较操作,还可能发生多重的隐式类型转换,例如true==['2']判断出的结果为 false,而true==['1']的结果是 true,还有[]==![]和[undefined]==false的结果都为 true…… (4)C++ 是不是弱类型语言? 前文提到《流畅的Python》中将 C++ 归为强类型,但实际上它应该被归为...
