Online Programming Assignment Help in the USA
We provide programming solutions to students studying in the USA in a wide variety of programming languages, some of which you’ve probably never even heard of. Introductory courses tend to concentrate on Python or Java depending, the reason being, both these languages are cross-platform and work easily on Windows and Linux.
Assignments in different courses on different programming language
Probably, Python is slightly better as an introductory programming language as there is less boilerplate. Although Python is an introductory language, it actually has a surprisingly deep level of complexity that it can support and it is often used in non-programming fields. For example, Biology and Python is a reasonably common combination as it has a wide library of modules that can easily be installed. Java is often used to illustrate an object-orientated programming language, it is much simpler than C++ as it handles the memory for you using a garbage collector. In addition to object-orientated programming, you will be introduced to data structures such as binary trees, linked lists, hash tables, and stacks. These are all fairly simple and have built-in library methods for them but you will implement them from scratch. Another advantage of Java is that it has a built-in library for GUI (Graphical User Interface). Writing a program that runs in a GUI is much more complicated than one that runs as a command-line program. A program that uses a GUI means you have to be able to switch between different contexts at any point and be able to display the state by updating the windows.
Later in your course, you may cover databases, which often use SQL (Structured Query Language). This is the standard for accessing data and works on the vast majority of databases. When working with databases you will need to normalize the data in order to make sure you only have a single copy of each field. For example, when dealing with invoices you don’t want to save the name of the item each time, you want to refer to a product. In SQL you need to join multiple tables together and you can also do the calculations whilst searching the data (for example, the maximum and the number of matching values). You may even be required to implement your own version of a database with a parser for a subset of SQL and a B+tree data structure.
Help with assignments in a low-level programming language
Lower-level programming should also be on your course, which will involve C and possibly Assembly language. C is used a lot on Linux as it is the main language that it was programmed in. C does not support object-orientated programming although you can implement it manually, it does not even have strings built into the language (it has an array of characters, which allows you to have a constant string, but all string operations are library methods). C is almost a processor independent version of assembly language without access to the lower-level implementation details. Assembly language does not have variables but instead has registers and memory addresses. There is normally a very small number of registers (32 at the maximum). These are much faster to access than main memory and should be used wherever possible. In Assembly Language, you need to push values to the stack to call a function. Hence, there are no easy facilities for debugging, there is not even a print command. There are a wide range of Assembly languages used in education, we have completed assignments in: -
8086 (using a virtual version of DOS)
x86 (under Windows)
68000 LC3 (an educational assembly language)
SPARC, MIPS, and ARM
You may not need to write much using an Assembly language, but it may be required if you are writing a compiler.
Assistance with Programming Assignments on Advanced Topics
Many universities in the USA in the final year of curriculum teach threading, multiple processes, synchronization, and memory management. These involve dealing with multiple interacting processes. Therefore, rather than adding all the values in an array to get the total, you might want to split the job into 4. Wherein, each thread or process is responsible for summing the values for its segment of the list and then the results are combined. This is fairly simple and does not rely on synchronization. But if you are dealing with more complicated data structures, for example, a web crawler, you need to add work to a queue as you explore. You may also cover functional programming languages, which operate differently than object-orientated ones. These include Scheme, Erlang, and Haskell. In functional programming, you don’t have variables (the values do not change, but you can calculate the value). The problem with functional programming is that you actually need to have a way to deal with non-pure functions to handle the input from a file or from the user. (A pure function will return the same value with the same arguments).
