Must use a structure type 必須使用結構類型

最佳回答：

#include<stdio.h>
#include<stdlib.h>
#include<CONIO.H>
typedef struct String{
    char string[100];

}
void Creat_List ( SqList *L )
{
        printf("Input a string:");
        scanf( "%s",&L->string);
}//錄入數據完成
// 
void Count(SqList *L)
{
    count = 0;
    for(int i=0;L->string[i]!='\0';i++){
        count++;
    }
}

void LoopUp(SqList* L)
