本文介绍了单链链印花c ++的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想以格式{1,2,3,4,etc}选择我的链。你可以找到下面的头文件,它将有节点的布局。我只是困惑,如何我应该骑自行车通过我的列表打印出项目。
I am trying to pick my chain in the format {1,2,3,4,etc}. You can find the header file below which will have the layout of the nodes. I am just confused on how I should go about cycling through my list to print out Item.
非常感谢任何指导。
set.h
using namespace std;
#include <iostream>
class Set
{
private:
struct Node
{
int Item; // User data item
Node * Succ; // Link to the node's successor
};
unsigned Num; // Current count of items in the set
Node * Head; // Link to the head of the chain
public:
// Return information about the set
//
bool is_empty() const { return Num == 0; }
unsigned size() const { return Num; }
// Initialize the set to empty
//
Set();
// Insert a specified item into the set, if possible
//
bool insert( int );
// Display the set
//
void display( ostream& ) const;
};
推荐答案
假设你的列表是循环的,
Suppose your list is cyclical, you can use this:
struct Node *n = begin;
if (n != NULL) {
//do something on it
...
for (n = begin->Succ; n != begin; n = n->Succ) {
}
}
或
struct Node *n = begin;
if (n != NULL) {
do {
//do something
...
n = n->Succ;
} while (n != begin)
}
