Este foarte simplu,o sa vezi ...
1.daca n-par => n-1:impar deci calculam n-1 si n-3
daca n-impar => n-2:impar deci calculam n-2 si n-4
CODUL:
#include <iostream>
using namespace std;
int main()
{ int n;
cout<<"nr=";cin>>n;
if(n>=4)
{if(n%2==0)
cout<<n-3<<" "<<n-1;
else
cout<<n-4<<" "<<n-2;
}
}
2.asemanator,insa aici adunam:
daca n-par => n+2 si n+4
daca n-impar => n+1 si n+3
CODUL:
#include <iostream>
using namespace std;
int main()
{ int n;
cout<<"nr=";cin>>n;
if(n>=4)
{if(n%2==0)
cout<<n+2<<" "<<n+4;
else
cout<<n+1<<" "<<n+3;
}
}
