将n个数按输入顺序的逆序排列，用函数实现

解： main()
{ int i,n;
char *p,num[20];
printf(“input n:”);
scanf(“%d”,&n);
printf(“Please input these number:\n”);
for(i=0,i scanf(“%d”,&num[i]);
p=&num[0];
sort(p,n);
printf(“Now, the sequence is:\n”);
for(i=0;i printf(“%d ”,num[i]);
}
sort(char p,int m)
{int i;
char temp,*p1,*p2;
for(i=0;i {p1=p+i;
p2=p1+(m-1-i);
temp=*p1;
*p1=*p2;
*p2=temp;
}
}
