A programming language is a comprehensive formal language containing a collection of instructions that produce different types of output depends on the information that is passed along during the course of execution. Programming languages are widely used in computer programming to perform various algorithms. One of the most important elements of a programming language is grammar or syntax. Grammar takes the form of rules defining the rules in a particular language. A programming language is also known as a domain-specific language.
Programs are normally written in one of three forms – high-level languages (high-order languages), object-oriented languages, or a mixture of the above. The programmer must ensure that the type of computer on which he/she is writing the program is compatible with the machine on which the application is to be executed. Compatibility among various types of computers is essential for software to run properly on computers. Programming language designers must take this into account because many computer programs are targeted to a specific operating system. Developers who are not aware of the compatibility issues involving various operating systems often fail to create a compatible program.
One of the main features of programming languages is their ability to provide source code, which consists of lines of specific instructions. The source code is a list of computer instructions written to a computer. All such instructions from the execution environment in which the programmer has to manipulate the computer. Each line of source code contains a single instruction and if the programmer uses the wrong instructions the programs will fail to execute.
A programming language makes it possible for the developer to use an abstract machine instead of a physical machine. This gives programmers a chance to control the execution environment in a better way than a physical machine can provide. Programmers can use virtual machines to translate virtual machines into executable instructions, and vice versa. Virtual machines allow programmers to avoid problems with pointer arithmetic, re-calculating amounts used by other programmers, and handling memory corruption that may occur due to incorrect programming practices.
to convert one type of data into another
A programming language makes it easy to write a specific task in a step-by-step fashion without the need of having to convert one type of data into another. For instance, programmers can write a series of instructions that should be executed to add two numbers together. They do not have to worry about converting an int into a floating-point number, or between two character counts.
A programming language also allows programmers to write code quickly
Developers can write code that loops over several results without having to multiply the original number with each loop. For example, they do not have to convert the result into a floating-point before performing the next operation. In general, high-level languages make it easier for programmers to write code that can perform several operations that can add, subtract, multiply, and divide the original value. Additionally, the languages make it easier to write code that can efficiently utilize all the resources available within the computer.
