数据结构编程求救
试验一:

using namespace std;

};
List *head=NULL;

数据结构c语言怎么运行啊
首先要确定你想采用线性表的顺序存储结构还是链式存储结构。
以顺序存储结构为例：
#include <stdio.h>
#include <stdlib.h>
#define ERROR 0
#define OK 1
typedef int Status;
typedef int ElemType;//顺序表测试用
const int MaxSize=; //只是主图买卖源码示例性的数据，可以根据实际问题具体定义
const int Increasement=;
typedef struct{
ElemType *elem;
int length;
int listsize;
}SeqList;
Status InitList(SeqList &S,猴王PHP源码int n=MaxSize)
{ //初始化线性表
if(n<=0)
n=MaxSize;
S.elem =(ElemType *)malloc(n*sizeof(ElemType));
if(S.elem ==NULL)
exit(ERROR);
S.length =0;
S.listsize =n;
return OK;
}
int ListLength(SeqList &S)
{ //求线性表的长度
return S.length ;
}
void GetElem(SeqList &S,int i,ElemType &e)
{ //按位查找，取线性表的Aspx上传源码第i个元素
if(i<1 || i>S.length )
exit(ERROR);
e=S.elem [i-1];
}
Status ListInsert(SeqList &S,int i, ElemType e)
{ //在线性表中第i个位置插入值为e的元素
if(i<1 || i>S.length+1 )
return ERROR;
if(S.length >=S.listsize )
{
ElemType *newbase=(ElemType *)realloc(S.elem,Increasement*sizeof(ElemType));
if(newbase==NULL)
exit(ERROR);
S.elem =newbase;
S.listsize =S.listsize+Increasement;
}
for(int j=S.length -1;j>=i-1;j--)
S.elem [j+1]=S.elem [j];
S.elem [i-1]=e;
S.length++;
return OK;
}
Status Output(SeqList S)
{ //遍历线性表，按序号依次输出各元素
if(S.length ==0)
return ERROR;
for(int i=0;i<S.length ;i++)
printf("%d\t",黑客表白源码S.elem[i]);
printf("\n");
return OK;
}
void BinInsertSort(int r[ ], int n)
{ //折半插入排序
int low,high,mid;
ElemType e;
for (int i=1; i<n; i++)
{
e=r[i];
low=0; high=i;
while (low<=high)
{
mid=(low+high)/2;
if (e<r[mid])
high=mid-1;
else low=mid+1;
}
for (int j=i-1; j>=high+1; j--)
r[j+1]=r[j];
r[high+1]=e;
}
}
void MergeList(SeqList La, SeqList Lb, SeqList &Lc) {
// 已知顺序表La和Lb中的元素按值非递减排列。
// 归并La和Lb得到新的aide源码翻译顺序表Lc，Lc的元素也按值非递减排列。
int La_len, Lb_len;
ElemType ai, bj;
int i=1, j=1, k=0;
InitList(Lc);
La_len = ListLength(La);
Lb_len = ListLength(Lb);
while ((i <= La_len) && (j <= Lb_len)) { // La和Lb均非空
GetElem(La, i, ai);
GetElem(Lb, j, bj);
if (ai <= bj) {
ListInsert(Lc, ++k, ai);
++i;
} else {
ListInsert(Lc, ++k, bj);
++j;
}
}
while (i <= La_len) {
GetElem(La, i++, ai); ListInsert(Lc, ++k, ai);
}
while (j <= Lb_len) {
GetElem(Lb, j++, bj); ListInsert(Lc, ++k, bj);
}
} // MergeList
void main()
{
SeqList La,Lb,Lc;
InitList(La,3);
InitList(Lb,5);
ElemType data;
printf("输入顺序表La的元素值：\n");
for(int i=1;i<=3;i++)
{
scanf("%d",&data);
ListInsert(La, i, data);
}
fflush(stdin);
printf("输入顺序表Lb的元素值：\n");
for(i=1;i<=5;i++)
{
scanf("%d",&data);
ListInsert(Lb, i, data);
}
//La和Lb非递减排序
BinInsertSort(La.elem , 3);
BinInsertSort(Lb.elem , 5);
MergeList(La,Lb,Lc);
Output(Lc);
}
