How to Avoid Programming Problems
Most beginners who start out programming computer software, applications, programs etc., run into many issues such as errors and bug-problems which most of the times program the whole programming problems and can at times the whole programming process can be very frustrating to the developer to a point of quitting. However these issues could be avoided if a programmer pays particular attention to some programming specific.
This guide will help address issues which can be avoided while programming thus offering you a smooth programming experience.
Programming without a plan.
When you start any programming work, you first need to develop a plan to be achieved by the project that you are working on. You need to specify the tasks that you need the project to accomplish. This includes the performance of specific features as well as the complete performance of the whole project. Then there must be a design which needs to be adhered to and should include all the details and specifics of the whole project. For more details, read this article.
Variations in coding style.
When coding there must be a specific style which is utilized for coding the whole project from start to end. A developer should avoid some writing styles such as being not consisted while indenting, don’t follow a specific convention in naming things etc.
When such a developer instead adopts a specific writing style, the whole programming process becomes natural for the brain to know what is expected at any given stage and also to identify any errors which may have resulted with much stress.
Improper use of global variables.
As a new programmer, you may find it easier to declare a programming variable global so that you can easily use it time and again when you wish. This might sound great but there are some variable which might be dependent on other functions or might have a value that you didn’t know about.
Therefore the variable may fail to be initialized, or get initialized incorrectly or gets initialized but since it is dependent on some other function, it gets reset to another value. Thus all your coding will yield unexpected results.
Incorrect Input validation.
There is always need to validate any input into the program such that any external input doesn’t result to the overflowing of any of the internal buffer and also when the program created is used for performing any queries, then the input does have controls that may override the program and leak out any queries undesired.
There must be controls to validate the program created and ensure that the input is in sync with the validation before the program can perform any task. The controls should also be able to detect and report any errors asap.
Failing to use a debugger.
A debugger is important ensuring that you can flip through all the code that you write and understand if it matches the details and specifics intended. A program may have a function that generates the desired results but the function might not be working as expected e.g. it might not be handling all the correct input values or it might not be able to work correctly at detecting any illegal input values.
