Create a program that get 10 even numbers from user

[akif13]

Hi. I need to enter numbers not more than 10 but it failed. I used while but it kept asking me to enter numbers.

The output should be like this:

Please key in 10 even numbers:
20
3
This is odd number! 3
12
30
44
24
96
10
9
This is odd number! 9
123
This is odd number! 123
36
78
94

using namespace std;

class ADTstack
{
    private:
        int stack[10];
        int topstack;

    public:
        ADTstack()
        {
            topstack = -1;
        }

        int empty()
        {
            if(topstack==-1)
                return 1;

            else
                return 0;

        }

        int full()
        {
            if(topstack==9)
                return 1;

            else
                return 0;
        }

        void push(int num)
        {
            if (!full())

                stack[topstack] = num;
            }

            else

                cout<<"Stack is Full"<<endl;

                return num;
            }

            else
            {
                cout<<"Stack is Empty"<<endl;
                return 0;
            }
        }
};

int main()

    ADTstack st;
    int num;

    cout << "Please key in 10 even numbers:" << endl;

    if (num % 2 == 0)

while (!st.full())
    {
        cin >> num;

        if (num % 2 == 0)
        {
            st.push(num);
        }

        else
