Programming paradigms
Applications and limitations
A procedural programming a program that contains a series of computational steps to be carried out. Procedural programming is a term to denote the way in which a computer programmer writes a program. This program works by using sequences of instructions. The types of procedural programming are pascal, c++ and c.
This is source code written in procedural language. y = 1224; for (x = 0; x < 100; x++) { z = y + x;
}
A variable y is being set, then the code enters a loop. this is showing procedural programing as it defines what the computer should do step by step.
It can be used for mathematical, science or engineering calculations that you want to be solved.
Limitations:
Procedural code is difficult to relate with real-world objects, this may make it difficult to design.
As the data is exposed to the whole program there is no security for your data. This could mean that a new programmer could corrupt the data accidentally by creating functions.
There are many types of procedural programming languages and the programmer might just specialise in a particular language as they can learn them all. as it written in a low level language it isn’t as efficient as others that many use high-level languages.
Object oriented
Object-oriented programming is a programming paradigm based on the concept of objects rather than algorithms, this may contain data in the form of fields. it aims to incorporate the advantages of modularity and
Unit 3: the computer programming code writing systems which is very fascinated topic programming come up with a great and focused based on three important computer programming code writing overview.
There are a lot of applications which are used to teach student coding and different programming languages. However, in order to use these application user need to have some coding concepts. There are many application which produce codes in an automation way. We will bring some of them, namely:
First let us take a look at computer programming. This element takes on different program designs created by engineers and uses one of several different programming languages to write executable code that computers can read. Programming is the source for
It surprised me that the program looked simple but once you start writing it was kind of hard involving a lot of thinking and
It is very much like a 3GL and for many programmers and program designers is the preferred way to state algorithms and program specifications (Learning Systems, 1997). Pseudocode is a "text-based" detail (algorithmic) design tool. The rules of Pseudo code are reasonably straightforward. All statements showing "dependency" are to be indented. These include while, do, for, if, switch. It can be written in ordinary English, and we can use some keywords in it too. For instance, to assign the value 5 to a variable y, we can write the pseudocode in any of the ways shown
You work as a junior technician in a small organization, Salchester PollUTest, which has recently started up following a split from a parent company. The managing director of the new organization, Gary, is looking to enhance the basic computer system that he currently has.
Algorithm:- An Algorithm is a major part of data structures which includes linked list, array ,trees, graphs etc that all are implemented using algorithm. An Algorithm is a sequence of instructions in a finite manner, written and executed in aspect to find the solution of a problem. For analyzing and defining an algorithm, we must consider its essential conditions:-
Speed Improvement: The execution speed improved by around 12% for common classes and 46% for core classes.
Procedural language executes instructions in a sequential manner. The above figure 1.2.1 shows the high level view of a procedural language
Languages, grammars and automata theory are all related to computer applications. Grammar is the rule for language structure regardless of the meaning. For computer programming languages context free grammar (CFG) is commonly used. Formal language as opposed to natural language must be used with computer applications because natural language is too vague for computer applications. Automata is a way to test an expression to determine if it is part of the language (Pfeifer, 2005).
Object orientation is one of the software development model playing role in software engineering. In object oriented analysis there are many problems facing by the software developers in order to replace all these and get the accurate results the developers are following the linguistic analysis. Linguistic completely relates on the set which has the other members included in it of structures from linguistic models and subset of models from the allocated examples. This method divide the information given by the clients and allocates it to the different frame work and then process it. The linguistic data mainly includes the words which focuses to components of object oriented analysis. The natural language information analyses
The C programming language (often, just "C") is a general-purpose, procedural, imperative computer programming language developed in the early 1970s by Dennis Ritchie for use on the Unix operating system. It has since spread to many other operating systems, and is now one of the most widely used programming languages. C also has had a great influence on many other popular languages,[1] especially [[C++]] which was originally designed as an enhancement to C. It is the most commonly used programming language for writing system software,[2][3] though it is also widely used for writing applications. Though not originally designed as a language for teaching, and despite its somewhat unforgiving character, C is commonly used in computer science
Ans: Object oriented programming organizes a program around its data,i.e.,objects and a set of well defined interfaces to that data.An object-oriented program can be characterized as data controlling access to code.
Programming languages over the years have improved and even changed drastically in their design and capabilities. New languages are created to perform specific tasks that others cannot accomplish each year. By doing so, the creation of these new languages fill specific niches. However, the problem with computer languages is that if you want to construct an easier approach to a task or problem in another language, odds are you must give something else up to accomplish that goal. Which is why there is such a large amount of different and unique programming languages.
