#Coding programs free handedly code#
Test cases must be planned while the code is being written, and they are developed while an application is coded. Testing is also a necessary part in the process of coding. A good programmer will parametrize these variables and configure them so the application can also be run and maintained in a different environment. If the code contains values referring to ‘absolute parameters’ such as file names, URLs or IP addresses, it will not run on a host that is of a different design. More code can be viewed on a page and programmer keystrokes can be reduced.Īnother feature of a good code is portability. An added advantage is if the code is also suitably compact. The code must also be conceptually simple. Simple code does not always depend on the length of the code. The next developer who uses the code may use it for a different purpose and may not even completely understand or utilise the complex logic.
To achieve a certain result, developers may use complex logic but this should be minimised while writing a good code. The key to a good code is also simplicity. To prevent this confusion and utter waste of time, descriptive names should be used. Often developers use Y1 or X1 as variables, and then do not replace them with meaningful names. Using good naming conventions is the next step to good coding. Name of the module, purpose of the module, description of the module, original author, modifications and authors who modified code with a description on why it was modified were components of an early commenting practice. However, comments reduce the cost of knowledge transfer. Once these are met, it becomes easier to follow some established good coding practices.Ĭommenting is one such practice that is often ignored by programmers, especially for codes that are written by multiple programmers. If needed, a mixed routine can be adopted. The next step is to measure existing programming languages against the requirements to decide on an appropriate one. A detailed design is a good guide for coding.

If there are some things that architecture cannot take care of, then those are handled in the software design phase. Software design is also of importance to clients, who can decide if their needs are being adequately addressed. Either a code is so simple that there are obviously no errors, or a code is so complex that there are no obvious errors. Hoare makes a good point when it comes to assessing software design and architecture. What is the design of the individual components? Such basic requirements have to be fulfilled when a good code is being written. What is the specific purpose of the software? The problem that the code is meant to solve must be clear to the developer.
An important question is how development is structured. The prerequisites that need to be in place for an efficient code covers matters like design and architecture. In absence of these, a code may be inefficient even if it is completed. This is easily the most important step of all.
