2. C Pointer to Pointer Till now we have used or learned pointer to a data type like character, integer etc. But in this section we will learn about pointers pointing to pointers. As the definition of pointer says that its a special variable that can store the address of an other variab...

stack:这就是我们经常所说的栈,用来存储自动变量(automatic variable) mmap:也成为内存映射,用来在进程虚拟内存地址空间中分配地址空间,创建和物理内存的映射关系 heap:就是我们常说的堆,动态内存的分配都是在堆上 bss:包含所有未初始化的全局和静态变量,此段中的所有变量都由0或者空指针初始化,程序加载器在加载程...
