problem 1148

我的代码：

#include<stdio.h>int main()
{int a[100];float sum=0.0,ave;int k,i;while(scanf("%d",&k)!=EOF){for(i=0;i<k;i++){scanf("%d",&a[i]);sum+=a[i];}ave=sum/k;for(i=0;i<k;i++){if(a[i]<ave){printf("%d ",a[i]);}elseprintf("\n");}}return 0;
}

正确代码：

#include<stdio.h>
int main(){int n,a[200],b[200];while(scanf("%d",&n)!=EOF){int s=0;for(int i=0;i<n;i++){scanf("%d",&a[i]);s+=a[i];}float ave=(float)s/n;int j=0;for(int i=0;i<n;i++){if(a[i]<ave){b[j]=a[i];j++;}}if(j==0)printf("\n");else{for(int i=0;i<j-1;i++){printf("%d ",b[i]);}printf("%d\n",b[j-1]);}}return 0;
}

反思：
没仔细看题，要按顺序打印。
