Pair programming is an agile software development procedure followed in Software development industry where two developers work using only one machine. Each one has its own keyboard and a mouse. One programmer proceeds as the driver who codes while the other will obey as the observer who will review the code being written, analyze and spell check it, while also dope out where to go next. Usually, the two programmers can switch their roles.  
Pair programming expands the man-hours needed to deliver code compared to programmers working independently. Demonstration capitulated miscellaneous outcomes, encouraging increases of between 15% and 100%. 

##Benefits of pair programming
* It increases code quality which leads to the comprehensible juncture of the entanglement and hidden details in coding tasks, diminishing the risk of error or going down blind pathways.
* Perfect transfer of skills, as junior developers pick up micro-techniques or extensive skills from more experienced team members.
* If the driver experiences a hitch with the code, there will be two of them who will solve the problem, hence two heads are better than one.
* Ordinary thinking is that it decelerates the project accomplishment time because you are productively putting two programmers to develop a single program, instead of having them work separately on two different programs. 
* Code fellas talk about how it could assist programmers to learn from their groups. It would permit programmers to get immediate face-to-face instruction, which is much better than online tutorials and quicker than finding resources on the Internet. 
* Associating on a single project assists your team to acknowledge the value of communication and teamwork.

##How does pair programming work?
The necessity for pair programming is nominal, two developers, and a shared command line or code editor. With these basic elements in place, there are so many processes to approach pair programming, from the [Ping Pong Pattern](https://dzone.com/articles/ping-pong-pair-programming) to much less organized forms. 

Pair programming is most effective when both people bring something distinctive to the table, whether that is awareness, circumstance, or a various perspective.

It works on specification, design, and complex programming tasks and experiments which specify that no quality enhancement is shown when working on simple tasks in a pair but there may be accurate improvements. Also, note that pair programming frequently involves activities other than writing code.

Each independent in a pairing has about a similar level of expertise, while pair programming is substantial for training in [software development companies](https://www.ifourtechnolab.com/custom-software-company), pairs are most occupied when they are about on the same level.

Rotating every day assists keep the current co-pilot engaged as individuals tend to grant most when they drive or sense they are about to drive.

Teams have revealed comfort in knowing about various parts of the system they are building. Pair rotation helps with knowledge shifts which diminish certain risks in the project.
 
In an academic setting, pairs are often allocated, moreover, industry they are normally self-assigned often during stand-ups. In both cases, pair programming is most productive when both individuals are inclined participants who can see value in the pairing activity.
