+- <h3>Input a variable</h3>
+`Input` helps you input variable on console. It can only be a variable.<br>
+The best part about this is that it automatically initialises an uninitialised variable to float and then takes the input.<br>
+The only drawback here being that, you can input only one particular variable in one input statement for now.<br>
+Let's see how it works!

+        input <variable>

+        EXAMPLE: (1) initialise x

 `Print` helps you print things on console. It could be statements or variables.<br>
 The best part about this application is that it understands whether you want to print a string or a variable.<br>
