Serial Monitor - multiple inputs

Hey all!

I got a noob question about multiple inputs through the serial monitor.

The first input I want is to decide between char '1' and char '2'.
When I press '1', I want a second input to write some data into array1 for example.
When I press '2', I want a third input to write some data into array2.

So basically I need one input to choose the next input.

The first input is:

void loop()
{
if (Serial.available())
  {
       inputChar = Serial.read();
        if        (inputChar == '1') {                                             
                                   ...code to write into array1....;
}
       else if   (inputChar == '2') {
                                   ...code to write into array2....;
}
else {
                                   Serial.println("invalid entry");
}
}

And my question is, how do I write the second/third input into this code?

Thanks
