Ajutor Problema Divizori Primi In C++

Recommended Posts

 Calculati suma si produsul divizorilor primi ai unui nr citit.(lucrez in Codeblock)

Nu stiu de ce dar imi da gresit si sper sa poata sa ma ajute cineva.

#include <iostream>

using namespace std;


int main()
{
    int n, d, s, p;




    cout <<"n=";
    cin >>n;


    for(d=1;d<n;d++){
     if(d%2>0 && d%3>0 && d%5>0 && d%7>0 && n%d==0);
     s=0;
     p=1;
     s=s+d;
     p=p*d;
     }


     cout <<"Suma divizori="<<s<<'n'<<"Produs divizori="<<p<<'n';


    return 1;


}

Respecta si vei fi respectat.

Nu prea inteleg ce e cu acel if.(ce-i drept , mintea mea nu mai lucreaza la cote bune la ora asta)

O chestie gresita pe care o vad : initializezi suma si produsul in if-ul din for.

Ar fi mai usor daca ai face un subprogram care sa verifice daca un nr este prim , faci un for de la 2 la jumatatea numarului , verifici daca i este nr prim , daca da : s=s+i , p=p*i.
