It should also have quality to easily meet new requirements. It should also prevent unwanted work so that the maintenance cost in the future will be low. If a program is easy to read and understand, then its maintenance will be easier. It is the process of fixing program errors and improving the program. Subsequently, if a program is developed only for a particular platform, its life expectancy is seriously compromised. A program is said to be more portable if it is easily adopted on different computer systems. So, portability is measured by how a software application can be transferred from one computer environment to another without failure. Because of rapid development in hardware and software, platform change is a common phenomenon these days. The program should compile and run smoothly on different platforms. These are the following characteristics of a good computer program- PortabilityĪ program should be supported by many different computers. What are the characteristics of a program which make it easier? It is good practise to write comments for every function, class, and property in your code. Structuring programming files in folders will make the code a lot more readable, maintainable, easier to locate, and organise files and versions.Ĭomments are invaluable in helping the next person who reads your code figure out what you were thinking when you wrote it, even when that person is yourself a month from now. That won't break your application, but it would be a bad experience to read, debug, troubleshoot, and maintain your application in the future. We should avoid writing all of our code in one or two files. It is decent practise to try not to write long lines of code. Developers use indentation to understand the structure of their programs for human readers. Indentation is the better way to represent the relationship between control flow constructs such as selection statements or loops and the code contained within and outside of them. Example: int amount Ĭorrect use of identifiers, white space, and documentation makes your program easier to understand. An identifier name should indicate the meaning and usage of the element in code. An identifier can be composed only of uppercase, lowercase letters, underscore, and digits, but should start only with an alphabet or an underscore. Identifiers are names for entities in a program, such as variables, arrays, functions, data definitions, labels, etc. These are some best practises we should always have in mind. While making great projects, we need to follow the specific rules of the programming language to make an effective program. A computer program is a sequence or set of instructions in a programming language for a computer to execute.
