What's the big picture? Programming, sometimes referred to as coding, is a nuts and bolts activity for computer science. While this book won't teach you how to program we've given some links to sites that can do this in the introductionwe are going to look at what a programming language is, and how computer scientists breath life into a language.
Different kinds of languages have been developed to perform different types of work on the computer. Basically, languages can be divided into two categories according to how the computer understands them.
A language that corresponds directly to a specific machine High-Level Languages: Any language that is independent of the machine There are also other types of languages, which include System languages: These are designed for low-level tasks, like memory and process management Scripting languages: These tend to be high-level and very powerful Domain-specific languages: These are only used in very specific contexts Visual languages: Languages that are not text-based Esoteric languages: Languages that are jokes or are not intended for serious use These languages are not mutually exclusive, and some languages can belong to multiple categories.
The terms low-level and high-level are also open to interpretation, and some languages that were once considered high-level are now considered low-level as languages have continued to develop. Low-Level Languages Low-level computer languages are either machine codes or are very close them.
A computer cannot understand instructions given to it in high-level languages or in English. It can only understand and execute instructions given in the form of machine language i.
There are two types of low-level languages: Machine language is basically the only language that a computer can understand and it is usually written in hex. In fact, a manufacturer designs a computer to obey just one language, its machine code, which is represented inside the computer by a string of binary digits bits 0 and 1.
The symbol 0 stands for the absence of an electric pulse and the 1 stands for the presence of an electric pulse. Since a computer is capable of recognizing electric signals, it understands machine language.Computer programming language, any of various languages for expressing a set of detailed instructions for a digital computer.
Such instructions can be executed directly when they are in the computer manufacturer-specific numerical form known as machine language, after a simple substitution process.
A system programming language usually refers to a programming language used for system programming; such languages are designed for writing system software, which usually requires different development approaches when .
The three basic types of control structures are sequential, selection and iteration. They can be combined in any way to solve a specified problem.
Sequential is the default control structure, statements are executed line by line in the order in which they appear. The selection structure is used to.
Computer programming language: Computer programming language, any of various languages for expressing a set of detailed instructions for a computer.
The earliest programming languages were assembly languages, not far removed from instructions directly executed by hardware. Although there are many computer languages, relatively few are widely used. Learning about different types of programming languages absolutely is constructive! You could potentially argue this should be closed as a duplicate of this but I think they're distinct enough questions to remain separate.
There is a basic assumption in your question that there is a difference between between a 'scripting' language and a 'programming' language.
