    minimum numbers to be entered into an array

    Is it possible to accept a minimum of ten numbers to be entered into an array? I know it's possible to accept a maximum of ten numbers to be entered into an array.

    Is this where vectors come in?

    dont let the loop leave until ten are taken

    Code:
    int somearray[10];
    
    for (int i = 0; i < 10; i++)
    {
    cout << "Enter int: ";
    cin >> somearray[i];
    }

    cin >> somearray[i];
    }
    That code doesn't look like it scans for a minimum of ten numbers; it looks like it's scanning for exactly ten numbers. What if I want to enter eleven numbers?

    I guess what I want is impossible to do with arrays...

    Code:
    for(int i=0; i<10; i++)
    {
       cin >> Array[i];
    }
    
    int Temp;
    int j = 10;
    do
    {
       cin >> temp;
       if(Temp != -1)
       {
          Array[j] = Temp;
          j++;
       }
    }while(Temp != -1)
    Assuming that the exit condition is the user enters -1.


    EDIT:

    Or even better:
    Code:
    int Temp;
    int i = 0;
    
    do
    {
       cin >> Temp;
       if(Temp != -1)
       {
          Array[i] = Temp;
          i++;
       }
    }while((Temp != -1) || (i < 10))

    well, if you want to change the size, vectors come into play. you can use resize() if you need to.

    or you could also use a linked list and dynamically allocate memory.
