问题描述
我正在尝试以 {1,2,3,4,etc} 格式选择我的链.您可以在下面找到包含节点布局的头文件.我只是对如何循环遍历我的列表以打印出 Item 感到困惑.
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.
任何指导将不胜感激!
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,你可以这样使用:
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)
}
