what is documentation
Documentation refers to the preparation of a written description of a problem, algorithms, flowcharts, graphs, coding, test results, instructions for the user, etc. That is, documentation is a set of documents or information that explains the operation required by a computer program, information system or data processing. Documentation should be done at every step of the programming, not at the end of the documentation. Documentation helps the programmer in all the steps of creating the program and as a result the program is maintained permanently. Without proper documentation, it can be difficult or impossible to change the program in any way, especially to someone else's program. That is why documentation is so important.
Usually the different stages of programming take time to compose, the first and second stages take up 45% of the total time coding 10%, input, debugging and documentation 45%.
