Count length of array and return 1 if it only contains one element

Question

cars    bmw   audi   volvo   vw  echo  cars length   returns 4  but    cars    bmw    returns 3 because it counts the characters    Is there a way I can return 1 if the array only contains one item

Instead of writing echo  cars length write echo    cars  length

Maybe I am missing something  lots of many-upvotes-members answers here that seem to be looking at this different to I  which would seem implausible that I am correct   but length is not the correct terminology for counting something  Length is usually used to obtain what you are getting  and not what you are wanting   cars count should give you what you seem to be looking for

declare you array as    car   array  bmw     EDIT  now with powershell syntax     car    array  bmw

A couple other options    Use the comma operator to create an array    cars     bmw   cars GetType   FullName   Outputs  System Object    Use array subexpression syntax    cars      bmw    cars GetType   FullName   Outputs  System Object      If you don t want an object array you can downcast to the type you want e g  a string array     string     cars     bmw    string     cars      bmw
