String or Char Arrays Length Definition

Erni:
You could read and count the characters until you reach the terminator, while you store the characters in a character array.
The terminator could be Carriage return, or other special you choose
If the count is >8, warn the user, ans start over.

This sounds great, though I'm not sure how to implement the If. I have this so far:

char Name[9]; // My Data array
char inChar; // Where to store the character read
byte index = 0; // Index into array; where to store the character


 if(index < 8){
           inChar = Serial.read(); 
           Name[index] = inChar; // Store it
           index++; // Increment where to write next
           Name[index] = '\r'; // Carriage to terminate the string
       }
else{
           Serial.println("Invalid Input, please enter 3 to 8 characters");
}

Will that work?
