Data Structures
</h4>
<p>
A data structure is a group of data elements that
provides the easiest way to store and perform
different actions on the data of the computer.
A data structure is a particular way of organizing
data in a computer so that it can be used effectively.
The idea is to reduce the space and time complexities
of different tasks. The choice of a good data structure
makes it possible to perform a variety of critical
operations effectively. An efficient data structure
also uses minimum memory space and execution time to
process the structure.

Algorithms
</h4>
<p>
The word Algorithm means ” A set of finite rules or
instructions to be followed in calculations or other
problem-solving operations” Or ” A procedure for
solving a mathematical problem in a finite number
of steps that frequently involves recursive
operations”.It can be understood by taking the
example of cooking a new recipe. To cook a new recipe,
one reads the instructions and steps and executes them one
by one, in the given sequence. The result thus obtained is
the new dish is cooked perfectly. Every time you use your
phone, computer, laptop, or calculator you are using
Algorithms.

like Windows, Linux, Unix, Mac etc.C++ is a
general-purpose programming language that was developed
as an enhancement of the C language to include
object-oriented paradigm. It is an imperative and a
compiled language.C++ is a middle-level language
rendering it the advantage of programming low-level
(drivers, kernels) and even higher-level applications
(games, GUI, desktop apps etc.). The basic syntax and
code structure of both C and C++ are the same.
