Walmart, which is the world's largest retailer by revenue, has applied to US regulators for permission to use drones for delivery, pickup and checking inventory.

Walmart had been initially testing the drones indoors, which have been made by China's SZ DJI Technology Co Ltd. Now, they hope to test outside.

 Using drones will help running the business easier and more convenient. These drones will do inventory of warehouses and speed up distribution of goods. In addition to using them at their stores and warehouses,they wish to use them for deliveries to their stores, as well as to their customers by delivering to their homes.

 To do this, Walmart needs permission from the Federal Aviation Authority. Then they will research into this and test out how the system is working and what needs to be tweaked and improved, as well as do risk analysis. WalMart spokesman Dan Toporek said the company would move quickly to deploy drones depending on its tests and regulations.

 Other companies such as Amazon and Google Inc have already taken this initiative.

Before we start, let me give you some basic concepts.

What is a Computer?

A computer is an electronic device that can follow instructions to
  • Accept input (data)
  • Process that input
  • Produce output (information)
Data: is raw, unorganized facts that need to be processed. Data can be something simple and seemingly random and useless until it is organized. For example, each student's test score.

Information: When data is processed, organized, structured or presented in a given context so as to make it useful, it is called Information. For example, the class' average score or the school's average score.

A computer is an electronic device operating under the control of instructions (software) stored in its own memory unit, that can accept data (input), manipulate data (process), and produce information (output) from the processing.

Generally, the term is used to describe a collection of devices that function together as a system.

What does a Computer do?

Computers perform four general operations which make up the information cycle.
  • Input
  • Process
  • Output
  • Storage

Programming Languages

Programmers write these instructions in different programming languages.
Programming-Languages

Machine Languages:
  • Strings of 0s and 1s
  • Directly understandable by computer
  • Defined by hardware of the machine
  • Hard for human beings to learn, error prone
  • Slow programming
Assembly Languages:
  • English like abbreviations
  • Not directly understandable by computer, hence require translator programs called "Assemblers"
  • Relatively easier for human beings to learn
  • Slightly faster programming
High Level Languages:
  • Developed for fast and speedy programming
  • Not directly understandable by computer, hence require translator programs called "Compilers"
  • Not dependent on hardware of the machine (mostly)
  • Easy to learn, less chances of error
  • Fast programming
Interpreters are another important category of translator programs.

Why C++?

C is a language designed by and for programmers. C++ is an expanded and enhanced version of C programming language. It is the language of choice for professional programmers worldwide. Once mastered, C++ will give you complete control over the computer. C++ is, above all, the most powerful programming language ever invented.

Basics of a typical C++ environment:
  • Program-development environment
  • Language
  • C++ standard library

The C++ Standard Library

C++ programs consist of pieces/modules called classes and functions. A programmer can create his own functions
  • Advantage: the programmer knows exactly how it works
  • Disadvantage: time consuming
Programmers will often use the C++ library functions as building blocks to avoid re-inventing the wheel
  • If a pre-made function exists, generally best to use it rather than write your own
  • Library functions are carefully written, efficient and portable
Phases of C++ programs
  1. Edit
  2. Preprocess
  3. Compile
  4. Link
  5. Load
  6. Execute
