The purpose of this article is to describe the features, principles and process of encoding and decoding Reed-Solomon codes. The number and type of errors that can be corrected depends on the characteristics of Reed-Solomon
codes. The paper is devoted to illustrate and to describe the ability of the working program to correct many errors in
the text file. This program is developed by C++ programming language to test of applicability of developed
algorithms. Thus, accuracy of programming algorithms has been tested. The article goes on to say about important of
this program and to appreciate the necessity of digital encoding applications.
