C :

#include <stdio.h>
int main(void)
{
	int c[10],i;
	float p;
	for (i=0;i<10;i++)
	{
		scanf("%d",&c[i]);
		p+=c[i];
	}
	p=p/10;
	printf("%.1f\n",p);
	for (i=0;i<10;i++)
	{
		if (c[i]>p)
		printf("%d ",c[i]);
	}	
	
	return 0;
}

C++ :

#include<iostream>
#include<cstdio>
using namespace std;
int main()
{
	int a[11],sum=0;
	for (int i=1; i<=10; i++)
	{
		cin>>a[i];
		sum+=a[i];
	}
	double ave=sum/10.0;
	printf("%.1lf\n",ave);
	for (int i=1; i<=10; i++)
		if (a[i]>ave) cout<<a[i]<<" ";
	cout<<endl;
	return 0;
}
