为什么输完数值后就结束了?

Question

#include <stdio.h>
#define MAXSIZE 100
typedef int elemtype;
typedef struct
{ elemtype *elem;
int len;
}SqList;

int init_Sq(SqList &L)
{ L.len=0; }

{ return L.elem[i] ; }

int disp_Sq(SqList L)
{ int i;
for (i=0; i<L.len; i++){
printf("%3d",L.elem[i]);}
printf("\n"); }

int search_Sq(SqList L, int key)

{ int i;
for (i=0; i< L.len; i++)

return -1; }

int delete_Sq(SqList &L, int i)

{ int j;

int insert_Sq(SqList L,int i,int x)

{ int j;
for (j=L.len-1; j>=i+1; j--)

}

int pre_Sq(SqList &L,int i)
{

scanf("%d %d",&k,&x);

printf("插入结点后的顺序表为：\n ");
disp_Sq(L);
return 0;
}

Answer 1

typedef struct
{
    elemtype elem[MAXSIZE];
    int len;
}SqList;

结构体修改一下！！
