C :

#include<stdio.h>

void main(){
    int n,i,c=0,s=0;
    double x;
    int a[100];
    scanf("%d",&n);

    for(i=0;i<n;i++){
        scanf("%d",&a[i]);
        s=s+a[i];
    }

    x=s*1.0/n;
    for(i=0;i<n;i++){
        if(a[i]>=x){
            c++;
        }
    }
    printf("%.1f %d %d",x,c,n-c);
}

C++ :

#include <iostream>
#include <iomanip>

using namespace std;

int main(){
	int a[100],i,j,n,t,s = 0;
	double v;
	cin>>n;
	for(i = 0;i < n;i++){
		cin>>a[i];
		s = s + a[i];
	}
	
	v = s * 1.0 / n;
	
	t = 0;
	//求平均分及以上的总人数
	for(i = 0;i < n;i++){
		if(a[i] >= v){
			t++;
		}
	} 
	
	cout<<fixed<<setprecision(1)<<v<<" ";
	cout<<t<<" "<<(n - t)<<endl;
}

Pascal :

var a:array[1..1000000] of longint;
    s:real;
    c,d,b,i:longint;
begin
read(b);
for i:=1 to b do
read(a[i]);
for i:=1 to b do
s:=s+a[i];
s:=s/b;
for i:=1 to b do
if a[i]>=s then inc(c)
else inc(d);
write(s:0:1,' ',c,' ',d);
end.

Java :

import java.util.Scanner;

public class Main {
	public static void main(String args[]){
		Scanner sc = new Scanner(System.in);
		int n=sc.nextInt();
		int[] a=new int[n];
		for(int i=0;i<n;i++){
			a[i]=sc.nextInt();
		}
		int sum=0;
		for(int i=0;i<n;i++){
			sum+=a[i];
		}
		double avg=sum*1.0/n;
		int s=0;
		for(int i=0;i<n;i++){
			if(a[i]>=avg){
				s++;
			}
		}
		System.out.println(String.format("%.1f", avg)+" "+s+" "+(n-s));
	}
	
}

Python :

n = int(input())
a = input().split()
# 初始化平均份av
l = []
su = 0
av = 0
# 初始化>=平均分的总人数
c1 = 0
# 初始化<平均分的总人数
c2 = 0
# 列表类型转换到新整型列表l
for v in a:
    l.append(int(v))
# 遍历l列表,计算成绩总和
for i in range(0, n):
    su += l[i]
# 求出平均数
av = su / len(l)
#遍历l列表,求出c1和c2
for v in l:
    if v >= av:
        c1 += 1
    else:
        c2 += 1
print('%.1f %d %d' % (av, c1, c2))
