Se citeste un vector cu n elemente intregi . Sa se afiseze :
1.Numarul elementelor pare
2.Media aritmetica a celor impare
3.Elemental maxim
4.Elemental minim

Answer 1

1)

int v[100],n,nr=0;
cin>>n;
for(int i=0;i<=n-1;i++){
cin>>v[i];
if(v[i]%2==0) nr=nr+1;
}
cout<<nr;

2)int v[100],n,s=0,nr=0;
cin>>n;
for(int i=0;i<=n-1;i++){
cin>>v[i];
if(v[i]%2==1) {
s=s+v[i];
nr=nr+1;
}
}
cout<<s/nr;

3)int v[100],n,x;
cin>>n>>v[0];
x=v[0]
for(int i=1;i<=n-1;i++){
cin>>v[i];
if(x<v[i]) x=v[i];
}
cout<<x;

4)int v[100],n,x;
cin>>n>>v[0];
x=v[0]
for(int i=1;i<=n-1;i++){
cin>>v[i];
if(x>v[i]) x=v[i];
}
cout<<x;
