Programming and information technology is now one of the most profitable areas. That is why most students choose this direction for studying and go to technical universities. However, even in technological universities, there are many unnecessary subjects for programmers, and in order not to waste time writing works on additional subjects, you can turn to AssignmentShark. The most important thing in programming is to know the programming language and be able to choose the most suitable one. That is why we have compiled for you a list of the best programming languages in 2020.
Why is the Programming Language Needed?
The programming language serves two interconnected purposes: it gives the programmer an apparatus for specifying the actions that must be performed and forms the concepts that the programmer uses, thinking about what to do. A language that is so “close to the machine” that all the basic machine aspects can be easily and simply operated in a way that is obvious enough to the programmer ideally answers the first goal. A language that is so “close to the problem being solved” ideally answers the second goal that the concepts of its solution can be expressed directly and shortly.
C ++ is a universal programming language designed to make programming more enjoyable for a serious programmer. With the exception of minor details, C ++ is a superset of the C programming language. In addition to the capabilities that C provides, C ++ provides a flexible and efficient means of defining new types. Using the definitions of new types that exactly correspond to the concepts of the application, the programmer can divide the developed program into easily verifiable parts. This method of constructing programs is often called data abstraction. Type information is contained in some user-defined type objects. Such objects are simple and reliable to use in those situations when their type cannot be set at the compilation stage. Programming using such objects is often called object-oriented. When used correctly, this method gives shorter, easier to understand, and easier to control programs.
In recent years, a need has ripened for a new language compiled into portable bytecode for the Java virtual machine. Several projects have appeared to create such languages, one of which is Kotlin, a statically typed object-oriented language compatible with Java and designed for industrial application development.
Kotlin is an object-oriented language, but, unlike Java, it allows you to declare functions outside of classes. In Java, static methods are used for these purposes, which leads to the appearance of classes that are actually not such: their instances are never created, and only static methods are called. The main decomposition tool in Kotlin, as in other object-oriented languages, are classes. When declaring a class, the list of constructor parameters is indicated directly in the header. The language is under development, and so far the specification is not fixed but it promises to be very good.
If you plan to work with databases, then you definitely need to learn SQL. It should be noted that at present, no system implements the SQL standard in full. In addition, in all dialects of the language, there are opportunities that are not standard. Thus, it can be said that each dialect is a superset of some subset of the SQL standard.
The basis of the SQL language is composed of operators conditionally divided into several groups of functions:
- DDL (Data Definition Language) operators – operators for determining database objects.
- DML (Data Manipulation Language) operators – data manipulation operators.
- Operators of protection and data management, etc.
As already mentioned, the standard language for accessing databases is now SQL.
Popular programming languages are the ones people are talking about. Even people far from programming probably heard about Java, C ++, SQL. Top programming languages periodically change places in the top twenty, but their composition is stable and reflects the real picture. Choosing a language from this list or at least from our list is a good idea. Good luck!
