2014 微软校招笔试答案 编程题

上午参加完微软校招笔试，最后编程题的代码，仅供参考

#include

using namespace std;


struct Node
{
Node *next;
        int date;
};


void createlist(Node**head,int a[],int length)
{

(*head)->next=NULL;
Node *p=*head;
for(int i=1;i {
Node *q=new Node;
q->date=a[i];
q->next=NULL;
p->next=q;
p=q;
} 
}

void showlist(Node *head)
{
while(head)
{
cout<date<<"----->";
head=head->next;


}
     cout< }




void Reoder(Node *head)
{

void main()

int a[]={0,1,2};
Node *head=NULL;
createlist(&head,a,sizeof(a)/sizeof(int));
showlist(head);
Reoder(head);
showlist(head);
