Programming language comprises instructions commanded by the user via computer hardware to reach certain objectives. They are types of programming languages that are used to run algorithms. The programming language comprises a set of algorithms used to instruct the computer to perform certain tasks. Programming languages act as a medium of communication between the user and the computer. Students who study programming languages look for computer science assignment help to complete their academic projects.

 

Types of Programming Language

Based on the semantics and the sequence of words used, the programming language can be classified into the following:

  • Procedural Programming Language: The compromise of executing certain statements to obtain a certain result. This programming language uses various elements such as loops and variables. The main purpose of these languages is to instruct the computer to perform a certain procedure. 
  • Functional Programming Language:  This language avoids loops in favour of various recursive functions. Unlike procedural language, this programming language cannot be used to store functions in the form of data.
  • Object-Oriented Programming Language:  In this programming language, the content is stored in groups of data called objects. The objects coordinate together to ensure that computers perform certain tasks. A single object in this language can be divided into a certain entity which ensures convenience for the user.
  • Scripting Language: This language uses some components of object-oriented programming to instruct different computers to perform certain tasks. These tasks are usually simple to command different computers altogether.

History of Programming Language

 

The programming languages have been developed with time. The development of these languages is in sync with the advances in the hardware capabilities of computers. The computer languages can be classified in accordance to the usage of different generations:

  • First Generation Programming Language: They are low-level machine languages. They were used to operate the computers, which used vacuum tubes as circuits. These computers used front panel switches as a means to operate the computers. There were no compilers available during that era to assemble the programming functions.
  • Second Generation Programming Language: They are low-level machine languages composed of the user's notions that are readable and converted into machine languages by the assembler. They were used to operate the 2nd generation computer, which used to function with the help of transistor circuits.
  • Third Generation Programming Language: This type of programming language introduced high-level languages understood by users and could be used to execute complex functions. 
  • Fourth Generation Programming Languages: They are considered an advanced version of the third-generation programming language; they are relatively easier to understand and learn. Using these languages, one can access the computer database.
  • Fifth Generation Programming Language: They are the latest generation of programming languages. The modus operandi of the programming language focuses on completing the task based on the object constraints rather than the algorithms instructed by the computer, which were used in the previous generation of computer languages.

Students who study computer language need to execute lengthy codes of programs as a part of their academic projects. To ease their workload, students look for help with computer science assignment. There are many computer science assignment experts who provide assessment help for students studying programming languages.
