C :

#include<stdio.h>
int main()
{
    int a[7];
    int max=0,min=24;
    double t,s=0;
    for(int i=0;i<=6;i++)
    {
        scanf("%d",&a[i]);
        if(a[i]>=max)
            max=a[i];
        if(a[i]<=min)
            min=a[i];
        s=s+a[i];
    }
    t=s/7.0;
    printf("%.1lf %d %d",t,max,min);
        return 0;
}

C++ :

#include <bits/stdc++.h>
using namespace std;
bool compare(int a,int b){
	return a > b;
}

int main(){
	int r[4010],i,n,k = 0,x;
	cin>>n;
	for(i = 0;i < n;i++){
		cin>>x;
		while(x != 0){
			r[k] = x % 10;
			x = x / 10;
			k++;
		}
	}	
	
	sort(r,r+k,compare);
	for(i = 0;i < k;i++){
		cout<<r[i];
	}
	
}

Pascal :

const n=7;
var
        a:array[1..n] of integer;
        i,k,max,min:integer;
begin
        for i:=1 to n do read(a[i]);
        max:=a[1];
        min:=a[1];
        for i:=1 to n do if a[i]>max then max:=a[i]
                                        else if a[i]<min then min:=a[i];
        for i:=1 to n do k:=k+a[i];
        write(k/n:0:1,' ',max,' ',min);
end.
