COROANA TE ROG!!!
C++
#include<iostream>
using namespace std;
int main(){
int x, s=0, p=1, k=0, k2=0;
do{
cin>>x;
s+=x, k2++;
if(x%2==0) k++;
if(x<0) p*=x;
}while(x!=0);
cout<<s<<' '<<p<<' '<<k<<' '<<(float)s/k2;
return 0;
}
PSEUDOCOD
s<-0, p<-1, k<-0, k2<-0
repeta
citeste x
s<-s+x, k2<-k2+1
daca x%2=0 atunci k<-k+1
daca x<0 atunci p<-p*x
pana cand x=0
scrie s, ' ', p, ' ', k, ' ', s/k2
