未初始化的数据段也被称为bss段(由符号开始的块 block started by symbol),被加载的程序在加载时为bss段分配内存.在C程序执行之前,bss段中的每个数据会被内核初始化为算数0(arithmetic 0)和指向空指针的指针(pointers to null pointer). bss段还包括所有被初始化为算数0的静态和全局变量以及指向空指针的指针 ...

Notes on Pointers Pointers are one of the things that make C stand out from other programming languages, likePythonandJava. They are important in C, because they allow us to manipulate the data in the computer's memory. This can reduce the code and improve the performance. If you are fami...
