顺序表的有序插入操作

6-40 顺序表的有序插入操作 (10 分)
本题要求实现一个函数,要求将指定元素插入到有序表的合适位置,使得插入后仍然保持有序,若插入失败返回0;插入成功则返回1,并且顺序表的长度加1.

函数接口定义:

int SqInsert(SqList &L,ElemType e);

其中SqList结构定义如下:

typedef struct{
    ElemType *elem;
    int length;
 }SqList;

裁判测试程序样例:

#include <stdio.h>
#include <stdlib.h>
#define MAXSIZE 5
typedef int ElemType;
typedef struct{
    ElemType *elem;
    int length;
}SqList;
void InitList(SqList &L);/*函数的实现此处不再显示*/
int SqInsert(SqList &L,ElemType e);
int main()
{
    SqList L;
    InitList(L);
    ElemType e;
    scanf("%d",&e);
    int result=SqInsert(L,e);
    if(result==0){
        printf("Insertion Error.The storage space is full!");    
    }else if(result==1){
        printf("Insertion Success.The elements of the SequenceList L are:");    
        for(int j=0;j<L.length;j++){
            printf(" %d",L.elem[j]);
        }
    }
    return 0;
}

输入格式:
输入数据有1行,首先给出以-1结束的非递减顺序表元素值(不超过100个,-1不属于顺序表元素,),然后是被插入元素值。所有数据之间用空格分隔。

输入样例:
4 8 20 -1 10
输出样例:
Insertion Success.The elements of the SequenceList L are: 4 8 10 20

供参考:

#include <stdio.h>
#include <stdlib.h>
#define MAXSIZE 5
typedef int ElemType;
typedef struct {
    ElemType* elem;
    int length;
}SqList;
void InitList(SqList& L);/*函数的实现此处不再显示*/
int  SqInsert(SqList& L, ElemType e);
int main()
{
    SqList L;
    InitList(L);
    ElemType e;
    scanf("%d", &e);
    int result = SqInsert(L, e);
    if (result == 0) {
        printf("Insertion Error.The storage space is full!");
    }
    else if (result == 1) {
        printf("Insertion Success.The elements of the SequenceList L are:");
        for (int j = 0; j < L.length; j++) {
            printf(" %d", L.elem[j]);
        }
    }
    return 0;
}
