What does a Computer Programmer do?
Computer programmers write, test, and maintain the instructions computers use to function. They also create and test programs that allow problems to be solved or specific tasks to be carried out via computer. Programmers work closely with computer software engineers who describe how software will work.
The job of a programmer is to take that design and use a programming language to turn it into a series of logical steps that can be completed by a computer. A different programming language is used depending on the nature of the program being written. Programmers also repair and update existing programs as necessary. Those in this field often use computer assisted software engineering tools or other applications that automate parts of the coding process. They may also customize existing basic code to meet their current needs.
Simple programs can be written in a few hours, but complex ones can take more than year to create. Once a program is written, a computer programmer must test it by running it. If errors occur or the desired outcome is not reached, the programmer must make changes to the code and re-test the program. Some programs require continual testing and debugging.
