2011年计算机等级考试二级C语言上机题库(10)
注意:源程序存放在考生文件夹的BLANK1.C中。
不得增行或删行,也不得更改程序的结构!
给定源程序:
#include
#include
#define N 8
typedef struct list
{int data;
struct list *next;
} SLIST;
SLIST *creatlist(int *);
void outlist(SLIST *);
int fun(SLIST *h)
{SLIST *p; int s=0;
p=h->next;
while(p)
{
/**********found**********/
s+= p->___1___;
/**********found**********/
p=p->___2___;
}
return s;
}
main()
{SLIST *head;
int a[N]={12,87,45,32,91,16,20,48};
head=creatlist(a); outlist(head);
/**********found**********/
printf(" sum=%d ", fun(___3___));
}
SLIST *creatlist(int a[])
{SLIST *h,*p,*q; int i;
h=p=(SLIST *)malloc(sizeof(SLIST));
for(i=0; i
{q=(SLIST *)malloc(sizeof(SLIST));
q->data=a[i]; p->next=q; p=q;
}
p->next=0;
return h;
}
void outlist(SLIST *h)
{SLIST *p;
p=h->next;
if (p==NULL) printf("The list is NULL! ");
else
{printf(" Head ");
do
{printf("->%d", p->data); p=p->next;}
while(p!=NULL);
printf("->End ");
}
}解题答案:
/**********第一空**********/
s+= p->data;
/**********第二空**********/
p=p->next;
/**********第三空**********/
printf(" sum=%d ", fun(head));
