很经典的数据结构ppt

#define OVERFLOW -1
typedef struct{
int m;
int n;}elemtype;
typedef struct {
elemtype *elem;
int length;
int listsize;
}sqlist;
void initlist(sqlist *l,int sm)
{l->elem=(elemtype *)malloc(sm*sizeof(elemtype));
l->length=0;
l->listsize=sm;}
int lsize(sqlist *l){
return l->length;}
void insertlist(sqlist *l,elemtype e){
l->elem[l->length]=e;
l->length++;}
void travel(sqlist *l){
int zzf;
for(zzf=0;zzf<l->length;zzf++)printf("\n%d 航班:%d\n",l->elem[zzf]);}
void dingp(sqlist *l,elemtype c,int j)
{int i;
for(i=0;i<l->length;i++)
 {if(l->elem[i].m==c.m && j)
  {if(l->elem[i].n>=c.n)
 {l->elem[i].n-=c.n;
  printf("订票成功!");}
  else
 printf("票数不足!");}
 if(l->elem[i].m==c.m && j==0)
{l->elem[i].n+=c.n;
printf("退票成功!");}}}
