uj5u.com熱心網友回復：
函式寫在主函式之后，都必須先生命函式原型。uj5u.com熱心網友回復：
函式宣告要在前，修改如下，供參考：#include<stdio.h>
#include<malloc.h>
#define a 10
typedef struct
{
int* data;
int length;
int Maxsize;
}SqeList;
void Insert(SqeList& L);//函式宣告在前
int main()
{
SqeList L;
Insert(L);//呼叫在后
return 0;
}
void Insert(SqeList& L)
{
L.data = (int*)malloc(a * sizeof(int));
L.length = 0;
L.Maxsize = 10;
}
uj5u.com熱心網友回復：
呼叫的函式在main函式之后的話需要宣告，之前則不用uj5u.com熱心網友回復：
#include<stdio.h>
#include<malloc.h>
#define MAX_SIZE 10
typedef struct
{
int* data;
int length;
int Maxsize;
}SqeList;
void Insert(SqeList& L);
int main()
{
SqeList L;
Insert(L);
return 0;
}
void Insert(SqeList& L)
{
L.data = (int*)malloc(MAX_SIZE * sizeof(int));
L.length = 0;
//L.Maxsize = 10;
L.Maxsize = MAX_SIZE;
}
