Is it normal to re-use code?

PROGRAMMING

I am curious about developers in the field and if most of their code is written by them or is it normal for developers to re-use old code and enhance it to meet their needs?

I'm just wondering because what I've been doing for awhile now is just re-using past code from previous projects to complete current once but editing them to meet my needs.

I do this often. The code i am re-using is my code but i usually reuse it if i need to to do the same task, no point in rewritting it.

A lot of developers do this. It is called "Snippets". You have snippets of code that you can re-use at anytime. This is code that you typically will use in each and every project.

  Reuse code implemented in other project let you save time for analysis, code and testing.
  
  It is not only smart but also more safe, because is code already tested, you' re simply developing your libraries, a code well-written is easy and safe to reuse.
  
  A my advice is also to keep always up-to-date about all the latest techniques and tools available for your language for increase the productivity, because are often requested by customers.
  
  ...my english is not well written, i dont like to reuse it.
  
  Thanks

  Recycling is good!
  
  But watch out for incompatibilities in old code. If you have been coding for a long time, or download projects from the internet written for example in PHP 4, and your current project is PHP 5.4 based, you might get bugs due to PHP version updates. Or the old code may need to be ported from global function and variable design to your object-oriented project.

  I have been programming since before there was dirt!
  
  A good developer always reuses code snippets to make the tasks of a new project go faster. As a seasoned developer who has programmed in many major languages, I have two pieces of advice.
  
  First, if you find yourself reusing code without making any changes (or very few changes), you should consider making that code a class or function that can be called from all of your projects. That way, if there is a bug that crops up, you only have to fix it one time.
  
  My second piece of advice: if you download code from the Internet to use in a project, make sure you understand how and why it works before putting it into your project. Many times, the code you download is very poorly documented. What I do if I download code code is to go through it and document it in my own words. That way, if I have to look at in the future, I don't have to figure out what it does all over again.

I use the same code across projects all the time, I mostly do it in a form of classes and make them as generic as possible without being tied to a particular project. When developing in wordpress I already have it as plugin to include all these classes. This way you re-use and the efficiency is better because your functions need to be generic and work across all the sites. Hope this helps.

Yes Of-course that's the way to save time and improve productivity!
Even in same program with the help of functions we reuse the same code as many time we want just by calling them.

It is very common. Not just normal. What is the point in inventing a block of code when you can re-use perfectly good example from your own work or another persons.

without examples and copy/paste code I would have never learned the little that I know ... without reusing code you would not be able to use answers from other people ..

so yes, normal and sometimes it's even recommended because some problems require smart solutions, and smart solutions don't just grow in your head all the time .

There's absolutely nothing wrong about reusing codes, in fact it's not a bad thing at all. I'm using that method and mix it up with my own set of codes, it saves me a lot of time doing so. Ofcourse you should understand what you are reusing, learn from it, play with it and then apply it to some more of your projects that you are gonna be doing.

Personally, it doesn't matter on how you write the codes, it's all on how your program works and thats all that matters.
