What is computer programming and High Level Languages

Today, a great many people don't have to know how a PC functions. The vast majority can essentially turn on a PC or a cell telephone and point at some minimal graphical object on the display, click a catch or swipe a finger or two, and the PC accomplishes something. A case would be to get climate data from the net and show it. Step by step instructions to communicate with a PC project is all the normal individual needs to know.
PC programming (frequently abbreviated to programming, some of the time called coding) is a procedure that leads from a unique plan of a registering issue to executable PC programs. Programming includes exercises, for example, examination, creating understanding, producing calculations, check of necessities of calculations including their rightness and assets utilization, and usage (usually alluded to as coding) of calculations in an objective programming dialect. Source code is composed in one or all the more programming dialects. The motivation behind writing computer programs is to discover a grouping of directions that will computerize performing a particular undertaking or taking care of a given issue. The procedure of programming in this manner regularly requires aptitude in a wide range of subjects, including information of the application space, particular calculations and formal rationale.

Be that as it may, since you are going to figure out how to compose PC programs, you have to know a tad bit about how a PC functions. Your employment will be to teach the PC to do things.
Assume that, as a software engineer, you are reached in light of the fact that your administrations are required. You meet with clients from the customer association to dissect the issue, or you meet with a frameworks investigator who plots the undertaking. In particular, the assignment of characterizing the issue comprises of distinguishing what it is you know (information given information), and what it is you need to get (yield the outcome). Inevitably, you deliver a composed understanding that, in addition to other things, indicates the sort of info, handling, and yield required. This is not a basic procedure.

PROGRAMMING LANGUAGES - HIGH-LEVEL LANGUAGES

Before we see what a PC programming dialect resembles, we should utilize the English dialect to portray how to accomplish something as a progression of steps. A typical activity that truly makes them consider what PC programming can be similar to will be to depict a procedure you are acquainted with.
All of the PC programming nowadays is finished with abnormal state programming dialects. There are loads of them and some are entirely old. COBOL, FORTRAN, and Lisp were concocted in the 1950s!!! As you will see, abnormal state dialects make it less demanding to depict the bits of the project you are making. They help by letting you focus on what you are attempting to do as opposed to on how you speak to it in a particular PC engineering. They unique away the specifics of the microchip in your PC. What's more, all abnormal state dialects accompany expansive arrangements of basic stuff you have to do, called libraries.

In this presentation, you will work with two PC programming dialects: Logo and Java. Logo originates from Bolt, Beranek and Newman (BBN) and Massachusetts Institute of Technology (MIT). Seymour Papert, a researcher at MIT's Artificial Intelligence Laboratory, and colleagues championed this PC programming dialect in the 1970s. More research of its utilization in instructive settings exists than for some other programming dialect. Indeed, the genuinely new Scratch Programming Environment (likewise from MIT) comprises of a cutting edge graphical client interface on top of Logo-such as usefulness.


BASIC

1. The first BASIC was initially created at Dartmouth College by John Kemeny, Mary Keller, and Thomas Kurtz and presented on May 1, 1964. Fundamental is short for Beginner's All-reason Symbolic Instruction Code and is a straightforward programming dialect that was famous amid 1970 - 1980. Today, BASIC is not used to create programs, but rather is now and then used to educate the essentials of programming. The following is a case of an essential program that prints "Hi World!".

10 print "Hi World!"

20 END

Albeit BASIC is not normally utilized today, new variations of BASIC, for example, Visual Basic are still famous and generally utilized.

2. When all is said in done fundamental depicts anything that covers all the important actualities or essentials required for a subject or expertise. For instance, any individual who has a fundamental comprehension of PCs has a general comprehension of how to utilize and work a PC.


COBOL

COBOL pinShort for Common Business Oriented Language, COBOL was initially showed up in 1959 as Grace Hopper, Bob Bemer, and others started their work in its improvement. Today COBOL is the second-most seasoned abnormal state programming dialect (FORTRAN being the most seasoned) is still being used by numerous organizations and governments.


FORTRAN

Short for FORmula TRANslator, FORTRAN was one of the primary programming dialects. FORTRAN started being made in 1954 by individuals from the IBM group, was initially acquainted with general society October 15, 1956 is still utilized today. The following is a brief history of FORTRAN.

1954 - FORTRAN

1958 - FORTRAN II

1958 - FORTRAN III (Never discharged to open)

1961-FORTRAN IV

1972 - FORTRAN 66

1980 - FORTRAN 77

1991 - FORTRAN 90

1997 - FORTRAN 95


C

C: prompt1. C is ordinarily used to depict the C: drive or the main hard drive on IBM perfect PCs.

How would I change drives in MS-DOS?

C programming book2. The C programming dialect is additionally an abnormal state programming dialect created by Dennis Ritchie and Brian Kernighan at Bell Labs in 1972 from a practically obscure dialect named B. The main real program written in C was the Unix working framework, and for a long time, C was thought to be inseparably connected with Unix. The following is an illustration of a C program that prints Hello World! After it's been assembled. On the off chance that you require a free C compiler, consider GCC.

#include <stdio.h>
main()

{

printf ("Hello World!\n");

}



3. C is a contraction for Celsius.

4. C speaks to the investigative unit for the coulomb.

5. Shorthand for see or sea.

C++       
C++ is an abnormal state programming dialect created by Bjarne Stroustrup at Bell Labs starting in 1979.

The first title of C++ was "C with classes". While he was a graduate understudy, Stroustrup was baffled that accessible dialects offered him either quick execution or abnormal state highlights for project association, yet not both. This propelled him to compose his own particular programming dialect.

He set out to make a programming dialect that gathers to incline, productive code, additionally gives abnormal state deliberations to better oversee expansive improvement ventures. The dialect was later named "C++", a facetious reference to ++, an administrator in C that additions a worth by one.

From that point forward, C++ has gotten to be a standout amongst the most generally utilized dialects as a part of the world, particularly in activities where execution comes at a premium. C++ keeps on being upgraded and kept up; the present rendition is C++ 11, discharged in 2011.

features

The sentence structure of C++ is to a great extent acquired from C. It adds object-arranged components to its forerunner, for example, classes, abstraction, encapsulation, inheritance, and polymorphism. It likewise gives usefulness to capacity and administrator over-burdening, nonexclusive programming offices, (for example, the capacity to make formats), and special case taking care of. C++ likewise highlights and a powerful standard library (STL) of helpful information structures, calculations, and data/yield offices.

Hi, World! In C++

Here is an illustration "Hi, World!" system written in C++, utilizing the I/O stream office; part of the C++ STL:

#include <iostream>

int principle()

{

std::cout << "Hi, world!\n";

}


Java
Java is a genuinely late programming dialect. It showed up in 1995 generally as the Internet was getting loads of consideration. Java was created by James Gosling, working at Sun Microsystems. It's kind of a medium-level dialect. One of the huge focal points of learning Java is that there is a considerable measure of programming officially composed ( see: Java Class Library) which will offer you some assistance with writing programs with elaborate graphical client interfaces that impart over the Internet. You get the chance to exploit programming that a large number of software engineers have effectively composed. Java is utilized as a part of an assortment of utilizations, from mobile phones to monstrous Internet information control. You get the chance to work with window objects, Internet association objects, database access items and a large number of others. Java is the dialect used to compose Android applications.

PHP

PHP logoCreated by Rasmus Lerdorf in 1994 and freely discharged June 8, 1995, PHP, which is short for PHP: Hypertext Preprocessor, is a server-side deciphered scripting dialect. It was intended for making dynamic site pages and site pages that adequately work with databases. The following are two samples of how you'd print "Hi World" utilizing PHP as a part of a .php document.

<? print("Hello World!") ?>

<? reverberation 'Hi world'; ?>

Documents that incorporate PHP code on a web server might have any record expansion; in any case, regularly end in .PHP, .PHP3, or .PHTML.
Python

Python1. Python is a deciphered, intuitive, object-arranged programming dialect that was initially created by Guido van Rossum and discharged in 1991. The following is a case of how you could print Hello World! in Python. This one line could be spared as hello.py and executed by writing: python hello.py from the order line.

print "Hi, World!"

Ruby

Ruby is an open source object-arranged programming dialect. The main variant of the dialect (0.95) was discharged in 1995, and in 2011, rendition 1.9.3 was discharged.

Ruby has been picking up ubiquity, and a structure called Ruby on Rails has expanded its use for web programming. The Ruby dialect is totally protest arranged, in that everything is an article. For example, even the most essential information sorts like whole numbers have strategies and case variables. This gives a more prominent capacity to utilize strategy tying, where numerous lines of code can be merged into one. For instance, on the off chance that you needed to utilize three distinct techniques on a string, one way would be to compose a few lines of code as demonstrated as follows.

x = "Computer".reverse

y = x.upcase

z = y.downcase

These strategies could rather be fastened, as appeared in the underneath code.

z = "Computer".reverse.upcase.downcase

Ruby is likewise known for being an adaptable dialect, since it takes into consideration developers to make alterations to different parts of the dialect if craved. More data on Ruby programming can be discovered utilizing the assets underneath.

Visual Basic

Visual BasicVB or Visual Basic is a programming dialect created by Microsoft with the assistance of Alan Cooper and was initially discharged in May 1991. Visual Basic was outlined on account of the apprentice software engineer and for developers who expected to create visual components in their projects. In Visual Basic, clients can drag and reposition visual components like windows, catches, and structures and afterward make occasions and triggers for those components.


Since its discharge, there were a sum of six unique forms of Visual Basic discharged (1.0, 1.0 for MS-DOS, 2.0, 3.0, 4.0, 5.0, and 6.0). The last form of Visual Basic, rendition 6.0 was discharged in 1998. After Visual Basic 6.0, Microsoft moved Visual Basic to the .NET Framework and Visual Basic got to be known as Visual Basic .NET, which is now and again alluded to as Visual Basic 7.0 and Visual Basic 2002 (year of its discharge). Subsequent to moving to the .NET structure there have been six renditions of Visual Basic .NET discharged (Visual Basic .NET, Visual Basic .NET 2003, Visual Basic 2005, Visual Basic 2008, Visual Basic 2010, and Visual Basic 2012).
