One-Pass CompilerOne pass compiler reads the code only once and then translates it. The one-pass compiler passes only once through the parts of each compilation unit. It can translate each part into its final machine program. In the one-pass compiler, when the line source is processed, it is scanned and ... Read More

The Chomsky hierarchy is a collection of various formal grammars. With the use of this formal grammar, it can generate some formal languages. They can be defined by multiple types of devices that can identify these languages such as finite state automata, pushdown automata, linear bounded automata, and Turing machines, ... Read More

The binding of a program element to a specific characteristic or property is the choice of the property from a set of possible properties. The time during program organization or processing when this choice is made is defined as the binding time of that property for that element. There are ... Read More

Programming environments have affected language design generally in two major areas such as features promoting separate compilation and assembly of a program from components, and features aiding program testing and debugging.Separate compilation − In the structure of any huge program it is regularly desirable to have multiple programmers or programming ...

The type conversion is an operation that takes a data object of one type and creates the equivalent data objects of multiple types. The signature of a type conversion operation is given as                   conversion_op :type1→type2There are two types of type conversions which ... Read More

Type checking is the activity of providing that the operands of an operator are of compatible types. A compatible type is one that is legal for the operator or is enabled under language rules to be implicitly modified by compiler-generated code to a legal type. This automatic conversion is known ...

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 ...
