Recap
Operators Blocks are used to do arithmetic and logical calculations.
Variables are the data values for which the value can be changed when the code
is being processed.
The statements that are executed on the basis of decision taken from a choice
are called conditional statements.
The program can also be developed to take input from the user.
The automatic running of a set of instructions more than once is called looping.
