C++ is the best programming language for quantitative finance that has been used by several financial institutions worldwide to develop their software. C++ was created by Bjarne Stroustrup in 1978 and is a hybrid, multi-paradigm language. It combines the features of imperative and object-oriented languages creating a powerful abstraction system that is a must in developing large-scale systems. A developer can use C++ object-oriented (OO) paradigms such as inheritance, polymorphism and encapsulation to build robust applications but yet keep efficiency by maintaining close control over memory allocation and freeing the resources automatically when they become unnecessary.
In this post, we review the aspects of Programming Language Used To Develop Accounting Software, best programming language for quantitative finance, programming language for payment gateway, and Is C++ used in finance?

Programming Language Used To Develop Accounting Software
Accounting software is a powerful tool that allows businesses to keep track of income and expenses, creating a more efficient way to run their companies. Of course, accounting software isn’t just for big businesses; if you’re an entrepreneur who wants to start your own business and needs some help with money management or even just want to be able to keep track of personal finances more easily, accounting software can really be a lifesaver. But what language do developers use when they’re building these programs? Well, there are many different programming languages out there—and while they all have their benefits and disadvantages, here’s what I think is the best fit for developing accounting software:
BASIC
BASIC stands for Beginner’s All-purpose Symbolic Instruction Code. It was developed in 1964 by John George Kemeny and Thomas Eugene Kurtz at Dartmouth College. The language was designed to be easy to use, write and understand. BASIC is a high level language which means that it gives programmers the ability to do more things with their code such as create programs using simple instructions rather than having to use machine language which is a series of 0s and 1s.
COBOL
COBOL (COmmon Business-Oriented Language) was developed in the late 1950s, and it’s still used today. It’s used in a wide variety of industries including business, finance and medicine. COBOL is also very popular for accounting software because it’s designed to handle numbers very well.
C++
C++ is a general-purpose programming language. It’s used for building applications for Windows, macOS, Linux, iOS, Android and web platforms. C++ is a compiled language that supports object-oriented programming (OOP) with classes and multiple inheritance.
C++ has become one of the most popular programming languages due to its flexibility and simplicity of use as compared to other popular languages like Java or C#. The main advantage with C++ over other languages is that you can write efficient code in fewer lines of code than with any other language.
Python
Python is a general-purpose programming language that can be used for many different purposes. It is open source and free to use, which makes it an ideal candidate for developing accounting software. Python also has a large standard library that allows you to perform common tasks with ease.
Python is interpreted, meaning that it can run on almost any platform without having to be compiled first. This comes in handy when setting up your accounting software because you don’t have to worry about compiling for each operating system individually.
Java
Java is a general-purpose programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.
It was originally developed by James Gosling at Sun Microsystems in 1991 and released in 1995 to provide an environment for distributed computing. In 2014 Oracle Corporation forked Java into two languages: Java SE (standard edition) and Java EE (enterprise edition). The intent of these changes was to create distinct versions targeted at different types of cross platform environments.
JavaScript
JavaScript is a programming language that is used to create interactive elements on web pages. It was created by Brendan Eich in 1995 and it’s an open source language. JavaScript is a scripting language and it’s not case sensitive.
In other words, if you want to write “JavaScript” in a sentence or phrase then it’s okay to capitalize this word (“JavaScript”) but if you want to type the variable name (for example: var x = 1) then you should write “JavaScript” without capital letters.
Perl
Perl, which stands for Practical Extraction and Reporting Language, is a high-level, general-purpose interpreted programming language. It was originally developed in 1987 by Larry Wall as a general-purpose Unix scripting language to make report processing easier. Since then, Perl has become one of the most popular programming languages in the world due to its flexibility and ease of use.
Today’s Perl is used for CGI (Common Gateway Interface) programming, system administration tasks such as repairing files and handling processes on remote computers, network programming including searching webpages or creating dynamic websites with CGI scripts.
Object Pascal (Delphi) and related languages such as Oxygene, FreePascal and Microsoft Visual Objects
Object Pascal is a programming language that was originally developed for the Borland Delphi version 1 in 1989. Object Pascal is a superset of Pascal, and is a programming language that is easy to learn.
The Object Pascal (Delphi) and related languages such as Oxygene, FreePascal and Microsoft Visual Objects are popular due to their ability to develop cross-platform, object-oriented applications.
QB64 (BASIC variant which supports most QBasic commands and adds new features – can run on 64-bit Windows operating systems)
QB64 is a BASIC interpreter for 64-bit Windows and Linux operating systems
It was developed by Jan van der Veen, who is also the developer of the QB64 compiler.
QB64 provides access to all capabilities of Microsoft’s .NET Framework and can be used in a similar way as the Visual Basic programming language, but with QBasic syntax. It supports most QBasic commands and adds new features, such as variables in modules (as opposed to only global), multi-dimensional arrays that are dynamically created on demand or limited by size, string formatting options similar to those of C# (such as “G” for general format or “D” for decimal format), support for enumerations, support for Math functions like SIN(x) and ATAN2(y/x), bitwise operations like XOR(a&b) etc., input/output redirection (pipes) from console windows using INPUT$() function which returns user input without displaying anything on screen – similar to keyboard_check() function in QB64; SCREEN$() function which retrieves screen information like height
Ruby
Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.
Ruby’s philosophy is to make programmers happy by supporting code that is readable, fast, and correct. Some of the features below can help you achieve this goal:
- Object-oriented design helps you structure your application more easily.
- Mixins allow the code reuse without any inheritance issues.
- RDoc generates documentation for each class automatically from its source files (current version 0.9)
Swift (via use of the Apple SDK)
Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. for iOS, macOS, watchOS, tvOS and Linux. Swift is designed to work with Apple’s Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C code written for Mac and iOS. It is built with the open source LLVM compiler framework.
Swift was introduced at Apples’ WWDC event on June 2nd 2014. The first beta release was made available to registered developers in August 2014; it was released a year later in September 2015 together with Xcode 6.2 as part of OS X 10.10 Yosemite and iOS 9; availability began on September 16th for free download from Apple’s website.[12][13] As of October 2017 it is estimated that 93% of App Store revenue comes from apps written in Swift.[14]
best programming language for quantitative finance
During a career in technology or quantitative finance, it is likely you will need to adapt to use a variety of different languages to put your ideas into practice, particularly if you are a trader looking to code your own algorithms. You may come across the dilemma of having to pick a language for yourself, your team or your organization to use. This is a tougher decision to make than may initially be apparent.
Picking a new language is a brave choice, easier to justify it provides a genuinely new programming paradigm, or it is your own language you are investing in, such as Python, which was supported by Google through much of its inception.
A sensible approach may be to identify all possible languages out there, evaluate the relative utility of each of them for your needs, and come to a final decision. If you are implementing low-latency/high-frequency trading algorithms, you may opt for C++ or Java to balance high performance with robust object orientation; if your needs are more in data science you may decide that Python is best with its large set of data extensions. If you have a need to produce an efficient database-driven web application, then C#/dot net may be the best choice.
The language may have already been decided by your employer, your client base, or the physical hardware you have access to. If it is a proprietary language, you may be fortunate to be able to evolve the tools you have to meet your needs, by adding extensions or integrating into other platforms.
Goldman Sachs and Morgan Stanley are known for having their own languages, Slang and A+, both completely different and both polarizing the opinions of those who used them, leading to people wanting leave to pursue opportunities involving more mainstream languages. I know of one Strat who left Goldman for Morgan Stanley for that reason, only to return within weeks after he found he liked A+ even less than Slang. It is certainly likely to be challenging if you have worked on a proprietary platform for years and seek to move to another firm, no matter how smart you are and how ground-breaking the work you have done. Alternatively, you may just find yourself going with something that is familiar to you, whether consciously or unconsciously.
If you are a long-standing C or C++ programmer then C++ is likely to be easy for you to justify with its backward compatibility and the benefit of many new features converging on other high-level languages. Generally though, style of the language elements you come across first, such as the print function and form or loop or variable declarations, may well have been influenced by earlier languages.
C# is a strange but useful language with its connectivity into various Microsoft technologies, but also is remarkably similar to Turbo Pascal from the late ‘80s/mid ‘90s, in no small way a result of Microsoft hiring Anders Hejlsberg, who was responsible for Turbo Pascal at Borland. Python is in many respects an odd- looking language with some issues around performance and robustness, and it may be that the aspects of it that made it feel familiar were the Monty Python quotes splattered around the code and its documentation. Its creator recently announced he will also be heading to work at Microsoft.
Ultimately though, large firms are investing heavily in the no-code area, so it seems likely that many of us will need to move to completely new platforms. The big question is where this no-code paradigm will take us. It’s likely that it will be a number of iterations before platforms emerge that can reliably replace all the topical programming languages and business application platforms.
