Salut! Am un program:
#include <iostream>
using namespace std;
int main()
{
for (int n=1; n<100; n++)
if (!(n%8==0)&&!(n%5==0))
cout<<n<<", ";
system ("pause");
return 0;
}
Si vreau sa-mi spuna la sfarsit cate numere am eu acolo.. adica nu sa le numar.. daca as schimba valoarea de 100, sa imi spuna exact cate numere imi afiseaza. Nu am idee ce sa folosesc. Puteti sa ma ajutati? |

#include <iostream>
using namespace std;
int main()
{
int i=0;
for (int n=1; n<100; n++)
if (!(n%8==0)&&!(n%5==0)){
cout<<n<<", ";
i++;
}
cout<<endl<<"Ai "<<i<<" numere";
system ("pause");
return 0;
