c中关于顺序栈操作的一个小程序,求救

recurrence1.c的代码:
#include"stdio.h"
#include "D:\study\dev program\sqstack9.c"
seqstack *a;
main(){
int x,n=0;
INISTACK(a);
printf("\nEnd with -1:");
scanf("%d",&x);
while(x!=-1){
a = PUSH(a,x);
n++;
scanf("%d",&x);
}
printf("n=%d\n",n);
while(EMPTY(a)!=1){
x = POP(a);
printf("%d ",x);
n--;
}
printf("n=%d\n",n);
getchar();
}
sqstack9.c的代码:
/*==================================*/
/* 5 fundary sequence stack operation */
/*==================================*/
#define true 1
#define Null 0
#define MAXSIZE 50
typedef int datatype;
typedef struct{
datatype stack[MAXSIZE];
int top;
}seqstack;
void INISTAC
#include"stdio.h"
#include "D:\study\dev program\sqstack9.c"
seqstack *a;
main(){
int x,n=0;
INISTACK(a);
printf("\nEnd with -1:");
scanf("%d",&x);
while(x!=-1){
a = PUSH(a,x);
n++;
scanf("%d",&x);
}
printf("n=%d\n",n);
while(EMPTY(a)!=1){
x = POP(a);
printf("%d ",x);
n--;
}
printf("n=%d\n",n);
getchar();
}
sqstack9.c的代码:
/*==================================*/
/* 5 fundary sequence stack operation */
/*==================================*/
#define true 1
#define Null 0
#define MAXSIZE 50
typedef int datatype;
typedef struct{
datatype stack[MAXSIZE];
int top;
}seqstack;
void INISTAC
seqstack *a;
main(){
int x,n=0;
INISTACK(a);
=================================
seqstack *a 没有初始化,INISTACK里
直接操作成员变量S->top = -1;
所以报运行时错。。。
加个
seqstack b;
seqstack *a = &b
鉴定完毕
