There are many professional categories in the domain of computer science. In this brief article, we look in to the responsibilities of computers programming professionals.
Coding, or in other words, program writing, is the main responsibility of computers programming professionals. For this there are dozens of programming languages available. In addition to that, the programmers are required to follow predefined conventions and standards when writing their code.
Writing the source code is just not enough to produce working software. The programmer is required to successful compile and link the source, so the program can work on the target platform. For this steps, there are software called compilers (such as C compiler), that convert source code to binary instructions.
Once the program is written by a computers programming professional, he/she is required to document the purpose of the source code and the business problem addressed by the software. In addition to that, the documentation should be sufficient for anyone to continue further developing the software.
Once computers programming professionals write individual components of software, the modules then need to be integrated. This is also performed by the programmer with the help of the software architect of the project.
Maintainability is one of the most important aspects of software development. If software is not maintainable, then it is not a good software program. Therefore, the computers programming professionals are required to add maintainability to their software.
Although we mention ‘Requirements analysis’ at a later point of this article than at the beginning, this is one of the most important first steps in the software development life cycle. The rule is that a programmer needs to know the requirement for writing a software program as he/she needs to write the program in such way that it meets the said requirements.
Largely, software testing is a different profession than computers programming profession. But, the programmers are required to dry-test their own programming code for obvious logical errors before the software program is passed to the software quality assurance team. Software quality assurance team then test for the software for functional and non-functional requirements specified by the clients.
Debugging is one of the last steps involved in computers programming. Once the quality assurance team finds ‘bugs’ in the software, the computers programming professionals are supposed to resolve the ‘bugs’. For debugging, programmer use different technologies and approaches depending on the tools used and the type of the ‘bug’. In general most of the functional and non functional bugs are caused by logical errors in the program level.
