摘要: 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

摘要: 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
