Challenge 2: Making a Calculator

Test your understanding of the conditional statement concepts covered so far by solving a simple challenge in this lesson.

We'll cover the following...

Problem statement

Write a code which will take:

  • Two variables named $num1 and $num2

  • A string type variable called $Operator which will be passed as input to our given statement

  • The $Operator variable can have any of the following values:

    • +,-,* and /

  • Use the given and when statements to perform:

    • addition
    • subtraction
    • multiplication
    • division

Sample input

$num1 = 5.5
$num2 = 6.5
$Operator = '+'

Sample output

Output = 12

Coding exercise

Write your code below. It is recommended that you try solving the exercise yourself before viewing the solution.

Good Luck!

Perl
#you are given variables $num1, $num2 containing some values 
#and an $Operator variable that contains the operator that is to be applied to $num1 and $num2 
#temp will contain the final answer after the required operation is performed
$temp=-76575; 
#write your code for given and when statements here
