Question

Learning objective: Explain and use three types of hash variables: Scalar, Array, and Hash or Associate Array Write the outputs of the following program segments make note of spaces and empty lines in the print statement point will be deducted for missing space and line in the output print "Learning scalar variable rightarrow/n^": $x = 10: print " value of scalar variable x: $x ": you can reassign $x to a different type $x = 'a': print " value of scalar variable x: $x ": print " Learning array variable rightarrow ": @x = (10, 20, 'a', 'b', 10.5, 20.5): print " Elements in array variable @x: ": print "@x ": print " size of array @x: ", scalar @x, " ": # Finding a specific element of an array print " First element of array @x: ", @x[0], " ": print " 3rd element from the end of array @x: ", $x[-3], " ": print " printing array @x: ": foreach $element (@x) { print "$element ": } print " Learning hash variable rightarrow ": %x = ("AM", Adarsh Mishra", "HE", "Harika Etha", "KC", "kai cobb", "PB", "Preston Bruuce"): # print "%x ": does not work like scalar or array printing

Explanation / Answer

Answer of Part-A:

Output:

Learnig scalar variable -->

Value of scalar variable x: 10

#Output after reassign $x to a different type

Value of scalar variable x: a

Learnig array variable -->

Elements in array variable @x:

10 20 a b 10.5 20.5

Size of array @x: 6

#Output for finding a specific element of an array

First element of array @x: 10

3rd element from the end of array @x: b

Printing array @x

10

20

a

b

10.5

20.5

Learnig hash variable -->
