顺序表实现和输入 输出问题

Question

#include <stdio.h>
#include<stdlib.h>
#define MaxSize 5 
//1 线性表的顺序存储---顺序表 
//定义结点
typedef struct LNode* List;
struct LNode {
int data[MaxSize];
int length;
};
List Make(){
    int i;
    List P;
    P = (List)malloc(sizeof(struct LNode));
    if(P){
        for(i=0;i<MaxSize;i++){
            scanf("%d",&P.data[i]);
            P.length++;
        }
    }
    return P;
}
void PrintList(List &p){
    int i;
    for(i=0;i<p.length;i++){
        printf("%d ",p.data[i]);
    }
}
int main(){
    List s;
    s = Make();

}

修改如下，供参考：

#include <stdio.h>
#include<stdlib.h>
#define MaxSize 5
//1 线性表的顺序存储---顺序表
//定义结点
typedef struct LNode* List;
struct LNode {
       int data[MaxSize];
       int length;
};
List Make(){
    int i;
    List P;
    P = (List)malloc(sizeof(struct LNode));
    P->length = 0;
    if(P){
        for(i=0;i<MaxSize;i++){
            scanf("%d",&P->data[i]);//scanf("%d",&P.data[i]);
            P->length++;  //P.length++;
        }
    }
    return P;
}
void PrintList(List &p){
    int i;
    for(i=0;i<p->length;i++){  //i<p.length;
        printf("%d ",p->data[i]);//printf("%d ",p.data[i]);
    }
}
int main(){
    List s;
    s = Make();
    PrintList(s);
    
    return 0;
}
