Question

Select the answer that would correctly replace the ???, to make the script return the desired output.

myScript.pl

# interpreter line intentionally omitted
$person1="Chelsey";
$person2="Sam";
???

Invocation and output

$ ./myScript.pl
Chelsey and Sam

Answer 1

The answer that replaces ??? that returns the desired output is:

print ($person1." and ".$person2);

To concatenate strings in perl '.'(dot operator) is used. In the above line, $person1 string is concatenated with the string " and " and this concatenated string is again concatenated with $person2.

Output after running the script is:

Chelsey and Sam
