Bash Scripting - Functions

Find the problem in this script:

myfunc() {
  echo "$1 and $3"
}
myfunc apple banana

A$3 is not passed, so it is empty

BFunction name is invalid

CMissing quotes around arguments

DCannot use $3 inside functions

Step-by-Step Solution

Solution:

Step 1: Check arguments passed to function
The function is called with two arguments: apple and banana. So $1 = apple, $2 = banana, but $3 is not passed.
Step 2: Understand effect of missing $3
Since $3 is not provided, it is empty, so echo prints "apple and " with nothing after.
Final Answer:
$3 is not passed, so it is empty -> Option A
Quick Check:
Missing argument $3 results in empty value [OK]

Quick Trick: Only passed arguments have values; missing ones are empty [OK]
