Do you want to do Math’s Ph.D.? Or are you looking for a D Programming Language Course? Accustomed to moving between increasingly higher-level languages, D Programming Language reminds us of the virtues of medium/low-level languages. Below is a functional analysis.
Anyone who starts in the world of programming today does so with languages like Java or Python; why? As you already know, Java and Python are high-level languages; this means that the language is in charge of managing some aspects of the processor, mainly memory management. For those of you who have worked with low-level languages, you will know that memory management is the most problematic aspect when programming since all exploits and vulnerabilities tend to slip through this area.
For this and other reasons, functional analysis of D Programming Language today is based on high-level languages. Many companies have developed their languages based on virtual machines, such as Microsoft’s C#, Apple’s Objective C/Swift, Oracle’s Java, etc. These languages have the advantage of not requiring definite memory management, and an intermediate entity generally interprets them. This virtual machine automatically handles many problematic aspects.
A little history of D Programming Language
To see the origins of the D programming language, we must go back to the late 1960s and early 1970s when Bell Labs released the B programming language. The B language was a simplification of the BCPL language, used to program the time’s microcomputers, intending to make it simpler and more usable.
A few years later, Dennis M. Ritchie of Bell Labs released an improved and refined version of his previous language, similar to the classic C language. In its predecessor, C’s focus was on the implementation of Unix-based operating systems. Still, unlike the previous one, C allowed working with higher-level structures while preserving low-level features.
In the early 1980s, with the spread of object-oriented languages, C naturally evolved to support this paradigm, and C++ was born by Bjarne Stroustrup. With C++, we had all the advantages of C, but with the added improvement, we could now create our own data types, complex functional structures, and inheritance and interfaces. In conclusion, we had an all-in-one language: it allowed us to control low-level features and use complex high-level architectures simultaneously.
C++ was the king of languages along with C; all other languages were implemented with C/C++ below. Although other languages existed, they were distributed for specific fields, while C++ allowed all-terrain development. But in 1995, something appeared that would change the history of programming, the Java language. This high-level language, initially developed to program washing machines, had incredible potential that, as you all know, has been propelled over time.
After the maturation of Java, its use spread exponentially. When working under a virtual machine, the management of low-level features is controlled by it, and the programmer can abstract from them. Furthermore, the cross-platform implementation means your code can be run on countless systems without recompiling.
Then the expansion of interpreted (or semi-interpreted) languages began, and medium/low-level languages started to be put aside. Leaving these mainly for the programming of microcontrollers and embedded systems. But in 2001, Walter Bright decided to release D Programming Language. A hybrid with the advantages of languages like C/C++ added to those of high-level languages.
High-level programming vs. low-level programming
High-level programming allows you to develop much more readable and simple code. In addition, practically all high-level languages have a built-in garbage collector, a software entity in charge of freeing the memory of resources that are no longer being used. For all these reasons, the current beginnings in programming are based on this type of language. Since we will focus more on logic and algorithms and leave aside aspects related to processor management.
But we can’t afford to keep a virtual machine in memory when we want to get the most out of system resources. Such as when programming embedded machines or resource-constrained systems. In addition, for critical systems, systems that require the intensive use of hardware resources, or simply systems. That we intend to optimize to the maximum, it is necessary to use medium/low-level languages such as C or C++.
With medium/low-level languages, we can distribute resources most efficiently since they allow us to work with memory addresses directly. Configuring aspects such as static space reservation, pointers that work directly with virtual addresses, or the manual release of resources. This makes us get the most out of system resources, but in return, our code will be more complex and challenging to understand. Meanwhile, check for Maths PhD. andD Programming Language Course here!
