Advantages and disadvantages of code cloning

 High code quality 
	 In knowledge sharing 、 Under the trend of open source code ,
		 More and more developers participate in the development of open source software ,
		 Constantly optimize open source software , Timely repair software defects ,
		 The quality and stability of open source software are increasingly improved 

 Low development cost .
	 In the process of software development ,
		 Demand analysis 、 System and detailed design 、 Coding and testing stages 
		 It takes a lot of manpower 、 Material and financial resources . 
	 After code cloning , Can improve development efficiency , Greatly reduce development costs 

 shortcoming ********************************

 The additional cost of development projects increases .
	 In open source projects , Strong professionalism 、 Incomplete comments and other reasons ,
		 Developers need to spend more time understanding the code ,
		 Thus, additional development costs are increased .
	 in addition , Large amount of open source project code , Reusing more associated code during code cloning will increase the total amount of code after development ,
		 This leads to an increase in compilation time , The demand for machine memory increases 

 Developing software is prone to vulnerability risks .
	 In open source projects , Although the software code has high quality and stability , But there are also potential vulnerabilities that have not yet been discovered ,
		 These vulnerabilities will increase the system risk , Reduce the security of the system .

 May infringe the copyright of open source software .
	 When using open source projects , Need to follow the open source license agreement (GPL,BSD,ApacheLicense etc. ),
		 If you use  GitHub You need to pay attention to copyright issues when coding .
	 When cloning code , If you use open source code illegally ,
		 It may infringe the software copyright and bear the corresponding consequences .
