problema 1 ------------
#include <iostream>
using namespace std;
int main()
{
int A, B, num, exista=0;
cout << "A= "; cin >> A;
cout << "B= "; cin >> B;
num=A;
while (num%11 !=0) ++num;
cout << " Multiplii lui 11 din intervalul [A;B] : \n";
while (num<=B)
{
cout << num << " ";
exista=1;
num=num+11;
}
if (!exista) cout << " nu exista...";
}
------------ problema 2 ----------------
#include <iostream>
using namespace std;
int main()
{
int sute, zeci, unitati, num;
cout << " Numere de trei cifre cu toate cifrele pare!" << endl;
for (sute=2; sute<9; sute+=2)
{
for (zeci=0; zeci<9; zeci+=2)
for (unitati=0; unitati<9; unitati+=2)
{
num=sute*100+zeci*10+unitati;
cout << num << " ";
}
}
}
