int main()
{
int v[100], i, p;
cout << "Introduceti primul element al vectorului ";
cin >> v[0];
if (v[0] != 0){
p = 1;
i = 1;
do {
cin >> v[i];
if (v[i] % 2 != 0){
p = p * v[i];
}
i++;
}

The SoloLearn environment only allows user input one time at the beginning when you run the program. You can enter multiple values on separate lines, but once the program is running there's no way to enter input again (like repeatedly from within a loop).
