DefinitionIt recognizes the code or data related to the name of the variable, function, class, etc. The definition is essentially needed by the compiler to designate the storage area for the declared entity. When a variable is defined it has an amount of memory that includes multiple bytes for that ... Read More

The whole source program can be processed several times before generating the assembly/machine code.Pass − One complete scan or processing of the source program. Various phases can be arranged into one pass. Lexical, syntax & semantic analysis are often grouped in a single pass. Each pass reads the source program ... Read More

A translator is a programming language processor that modifies a computer program from one language to another. It takes a program written in the source program and modifies it into a machine program. It can find and detect the error during translation.There are various types of a translator which are ...

A declaration in a program refers to a statement that provides the data about the name and type of data objects to the programming language translators. For example, consider the following C declaration −int a, b;This declaration provides the programming language translator with the information that a and b are ... Read More

An elementary data object includes a single data value and a class of elementary data objects with a set of operations for creating and manipulating them is represented as an elementary data type. An example of elementary data types such as integer, real, character, Boolean, pointer, etc.The basic components of ... Read More

A compiler is a computer program that changes source code written in a high-level language into low-level machine language. It translates the code written in one programming language to some other language without modifying the definition of the code. The compiler also produces the end code efficient which is optimized ... Read More

In a language processing system, the source code is first preprocessed. The modified source program is processed by the compiler to form the target assembly program which is then translated by the assembler to create relocatable object codes that are processed by linker and loader to create the target program. ...

In a computer, the data is stored in memory, registers, and external media.Generally, all these devices have an approximately simple structure as a sequence of bits arranged into bytes or words. However, data storage of the virtual computer for a programming language influence to carry a more complex organization with ... Read More

There are various attributes of programming language in compiler design which are as follows −Simplicity and Clarity − Few languages such as Basic, Algol, and Pascal in the past were purposely created to simplify clarify of expression. Basic, for example, had a very small instruction set. Algol 60 had a ... Read More
