Programming entails the creation of different programs to express algorithms and various problems are designed alongside these algorithms. These problems require solutions that are designed using the Problem; Design; Solution format to code specific and which are combined into a complete web application. Different programming problems include non-coprime sequences, connected permutations and retroactive integers among others. Thus, designing a program requires a programmer to comment on the code, hide and encapsulate data and inheritance to make the program easy and flexible.
One of the biggest challenges experienced when planning and designing a solution for a programming problem includes multithreading, which is done in order to execute two or more parts of a program. Dividing a program into multiple independent sections so that an operating system can run them separately seems to be easy until the time when they require to access the same variables or require bits to be written to same files. If the processors have four or more cores, it is easy to write the codes into four or more threads and handled independently. It should be noted that multiple threads share the same memory address space and thus they can access the same objects and variables within a process (Goetz). Thus when the need arises, it is difficult to allocate the same variables to all the threads and only one of the threads gets the data (Wayner, 2016). This causes the programmer to create tools such as semaphores in order to try and organize the threads but this only results in the formation of a more complex thread that is difficult to understand, and whose columns do not add up, resulting in chaos and no solution.
Delegate your assignment to our experts and they will do the rest.
Little memory as a result of too much data is also another challenge that programmers face when trying to come up with solutions. When the RAM has no more space, the virtual memory starts to fill up space in the hard disk and as a result, the software begins to unction slowly. This case is worsened when a separate process is trying to read or write from the disk since the process is slowed down as the drives will only be able to transfer items one at a time. The lack of memory results in breakdown of threads that may have been formed and those being run in the hard disk get stuck in the virtual memory for a short time. It also results in slower generation of the result in case the coding is perfect. When the coding is wrong, the thread then completely crashes and results in failure.
Security is also a major concern for programmers since they are at a risk of getting hacked and their solutions being stolen. Hackers are able to gain access to the software layer buried inside the user’s networking hardware that provides a hole through which they can steal any programming solutions that a programmer may have prepared.
The solutions to these challenges vary. In order to tackle the challenge of multithreading, a programmer is required to rewrite a single thread program in order to make it easy for the thread to access the variables provided and to write bits to the same file. This will reduce the chances of a mess occurring and this makes it easy for the programmer to lock down the data structure, making it easy to handle the programming. In the case of lack of enough memory, a programmer should try to break down the large load of data in order to reduce the data structures and lower the risk of hardware crushing down. Since security is a major concern for all computer owners. Programmers can batten down their passwords to reduce chances of being hacked (Wayner, 2016).
Single threading can be applied in class when writing programs and their solutions since it is easy to execute a program containing a single thread rather than multiple threads. Large data can be well executed using multiprocessor systems, such as Linux, which can be made available in class in order to allow for execution of any number of threads (Goetz). If these are not available, then only small amounts of data should be used to write a programing solution. The creation of difficult passwords is a skill that should be taught in class, and focus should be on the software inside the networking hardware which most hackers target.
In conclusion, it is important for programmers to ensure that they deal with other challenges beforehand to ensure that the solutions they design are not destroyed or stolen.
