Comparison of Original Code vs. Modified Code


Introduction to Code Comparison

Why do we compare anything? Have you ever thought about it? Things compare mainly to judge their similarities or differences based on which an accurate decision can take. It is also the prime purpose behind code comparison & by comparing two or more codes and taking details of their quality such as differences or similarities etc. But now the question is, what is the code comparison? When two source code files compare, it is a code comparison, which has two purposes:

  • To acknowledge the formation of codes
  • To find out & show its similarities & dissimilarities.

Comparing similar files between the two versions is a daunting task. Because sometimes, there are so many minor changes in them that are beyond the reach of any human being. Plus, doing this work manually also consumes a lot of time where even 100% output expecting to be negligible. But the end of all these problems is possible through code comparison. Code compare tools are the best tools through which it becomes uncomplicated to compare two files and folders. These files can be anything like text files, XML, JSON, source codes, strings, or any other binary files. It recognizes by the code similarity checker tool & shows you the results, differences, similarities, or differences between two files or folders. These tools can use with the help of the following steps:

How to use the code comparison tool?

  • First of all, open any code comparison tool.
  • Now, paste the first code or text file in its first or left column & paste the second code or text file i.e. with which you want to compare in the second or right column. 
  • Between two columns, you find an arrow sign that allows you to link two columns with each other or to make parallel movements of two columns with each other while scrolling. For this, you click on the arrow.
  •  If there is any difference between any lines of two codes or text files, it will get highlighted.
  • Save options are also present in the tools, where you can also save files for further uses.

Above are the basic steps for comparing code or text in any tool, although some may take longer steps because of extra features, while some can accomplish this task in less time because they are automatic.

After knowing the steps, let's see the 15 best tools for doing things like code or text comparisons in a pinch. They are as follows:
