fwrite(t, sizeof(STU), N, fp);

fclose(fp);

fp = fopen("student.dat", "rb");

fread(ss, sizeof(STU), N, fp);

fclose(fp);

printf("\nThe original data :\n\n");

for (j=0; j

{ printf("\nNo:

%ld Name:

%-8s Scores: ",ss[j].sno, ss[j].name);

for (i=0; i<3; i++) printf("%6.2f

", ss[j].score[i]);

printf("\n");

}

fun("student.dat", n);

printf("\nThe data after modifing

:\n\n");

fp = fopen("student.dat", "rb");

fread(ss, sizeof(STU), N, fp);

fclose(fp);

for (j=0; j

{ printf("\nNo:

%ld Name:

%-8s Scores: ",ss[j].sno, ss[j].name);

for (i=0; i<3; i++) printf("%6.2f

", ss[j].score[i]);

printf("\n");

}

二、程序改错题

#include

typedef struct aa

{ int data;

struct aa *next;

} NODE;

NODE *Creatlink(int n, int m)

{ NODE *h=NULL, *p, *s;

int i;

p=(NODE

)malloc(sizeof(NODE));

h=p;

p->next=NULL;

for(i=1;

i<=n; i++)

{ s=(NODE

*)malloc(sizeof(NODE));

s->data=rand()%m; s->next=p->next;

p->next=s; p=p->next;

}

return p;

}

outlink(NODE *h)

{ NODE *p;

p=h->next;

printf("\n\nTHE LIST :\n\n HEAD

");

while(p)

{ printf("->%d ",p->data);

p=p->next;

}

printf("\n");

}

main()

{ NODE *head;

head=Creatlink(8,22);

outlink(head);

}

三、程序编写题

#include

#define N 80

int fun( char *s)

{

}

main()

{ char

line[N]; int num=0;void NONO ();

printf("Enter a string

:\n"); gets(line);

num=fun( line );

printf("The number of word

is : %d\n\n",num);

NONO();

}

void NONO ()

{

FILE *rf, *wf ; int i, num ; char line[N], *p

;

rf = fopen("K:\\k01\\24010001\\in.dat","r")

;

wf = fopen("K:\\k01\\24010001\\out.dat","w")

;

for(i = 0 ; i < 10 ; i++)

{

fgets(line, N, rf) ;

p =

strchr(line, '\n') ;

if(p !=

NULL) *p = 0 ;

num =

fun(line) ;

fprintf(wf, "%d\n", num) ;

}

fclose(rf) ; fclose(wf) ;

}
