void insert(){
        for(int j = 0 ; j < 10 ; j++){
            cout << "nElement you want to insert: (" << i+1 << "). ";
            if(cin >> A[j]){
                i++;
            }
            else{
                cout << "nWrong Input" << endl;
                break;
            }

Solution

Here’s one way to write your insert function

void insert()
{
    int v;
    for(int j = 0 ; j < 10 ; j++)
    {
        cout << "\nElement you want to insert: (" << i+1 << "). ";
        if (cin >> v)
        {
            if (i < 10)
            {
                A[i] = v;
                i++;
            }
        }
        else
        {
            cin.clear(); // clear error
            cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n'); // discard any pending input
        }
    }
    if (i >= 10)
        cout << "\nYour List Capacity is Full.\n" << endl;
}

The important part is the recovery from bad input. First cin.clear() is called to clear the stream error state, secondly cin.ignore(...) is called to discard any pending input.
