const主要是为了程序的健壮型,减少程序出错.
最基本的用法:
const int a=100; b的内容不变,b只能是100也就是声明一个int类型的常量(#define b =100)
int const b=100; //和上面作用一样
const指针和引用一般用在函数的参数中
int* m = &a; //出错,常量只能用常指针
int c= 1;const int*pc = &c;//常指针可指向常量

堆和栈的区别
一、预备知识—程序的内存分配
一个由c/C++编译的程序占用的内存分为以下几个部分
1、栈区(stack)— 由编译器自动分配释放 ,存放函数的参数值,局部变量的值等。其操作方式类似于数据结构中的栈。

A Tree Manipulation Library
Whenever you implement a new data type, it is usually a good idea to provide functions for manipulating it. There is a general concept in computer science referred to as the black box principle. It is the idea that the user of a data type should not need to be aware of how it is implemented because a library of functions is provided to interact with. This library separates the user from the implementation. This is a good idea because it allows you the progra 阅读全文
