Question

50 puncte. Se considera tabloul A[1..N] de numere naturale, N<=100. Scrieti un program care calculeaza suma elementelor divizibile cu 3 si 7.

Answer 1

#include <iostream>

using namespace std;

int main()

{

int A[101], N, i, s=0;

cout<<"N="; cin>>N;

for(i=1;i<=N;i++){

 cout<<"A["<<i<<"]="; cin>>A[i];

}

for(i=1;i<=N;i++)

 if(A[i]%3==0 && A[i]%7==0)

  s=s+A[i];

cout<<s;

return 0;

}
