菜鸟求助....#include<iostream> #define MAX 1000 using namespace std; main() { int a[MAX]; int i=1; do { cin>>a[0]; int n=0; int cup=0,cdown=0; int up=0,down=0; int flag=-1; int t=0; if(a[0]==0) break; i=1; do scanf("%d",&a[i]); while(a[i++]!=0); n=i-1; for(i=1;i<n;i++) { if(a[i-1]<a[i]) { cup=1; flag=0; break; } if(a[i-1]>a[i]) { cdown=1; flag=1; break; } } for(i=1;i<n;i++) { if(a[i-1]<a[i]) { up++; if(flag==1) cup++; flag=0; } if(a[i-1]>a[i]) { down++; if(flag==0) cdown++; flag=1; } if(a[i-1]==a[i]) { if(flag==0) up++; if(flag==1) down++; } } if(cup==0) cup=1; if(cdown==0) cdown=1; printf("Nr values = %d %f %f\n",n,float(up)/cup,float(down)/cdown); }while(1); } 题目给出的数据都对了啊,式输入输出的问题吗? 哪位大哥指导一下,或者给几组错误数据,或者给个ac的代码都好,谢谢 Followed by:
