Programming is a way of sending instructions to the computer. To create these instructions, programmers use programming languages to create source code, and the source code is then converted into machine (or object) code, the only language that a computer understands. People, however, have difficulty understanding machine code. As a result, first assembly languages and then higher-level languages were developed. That the require languages Programming information in the BE Provided a Certain order and structure, symbols That the BE USED, and is even sometimes Do That punctuation
the BE USED. The rules are Called for These the syntax of the programming language, and for They Vary a great deal from one's language to another.
The Categories of the Languages.
Based on Evolutionary the history, programming languages fall Into the one's of the following a three Broad categories:
Machine the Languages. Machine languages consist of the 0s and 1s of the binary number system and are defined by hardware design. Computer understands only A machine its 'language - the commands The instruction in the set its' That INSTRUCT the computer to the perform the Operations ELEMENTARY such as with loading, Storing, Adding, subtracting and.
The Assembly the Languages. These languages were developed by using Englishlike mnemonics . Worked in text Programmers editors to the create-source Their files is.
The To-source files is the convert the below code Into the object, Researchers Created by translator programs Called assemblers. Languages are to still the Assembly much Easier to use than machine language.
Higher-Level the Languages. These languages use syntax that is close to human language, they use familiar words instead of communicating in digits. To express computer operations, they use operators , such as the plus or minus sign, that are the familiar components of mathematics.
