Programming Languages and Compilers

Lexical analyzer reads the source program one character at a time, carving the source program into a sequence of atomic units called tokens.

Syntax analyzer phase imposes on a token a tree like structure called as parse tree.

Macro is a unit of specification for program generation through expansion. 

This programming language does not support query language proposal for the ODMG object model.

It can also refer to the development of successively more complex, faster programming environments.

It reads the source program one character at a time, carving the source program into a sequence of atomic units called tokens.

It allows a user to specify a possibly ambiguous grammer along with precedence and associativity information about operators.

It is the gap between the semantics of programs, written in different programming languages.

This grammar production specifies that derivation or reduction of strings can take place only in specific contexts.

It has been designed to look familiar to a programmer who has already written API based code in windows.

Option (3) is correct.

Reserved words are terms that programming languages set aside for specific purposes and cannot be used as identifiers (variable names, function names, etc.). Examples include 'if', 'while', 'class', 'return' in most languages.

 Programming language built into user programs such as Word and Excel are known as visual programming languages.

Content coupling (also known as pathological coupling) is when one module modifies or relies on the internal workings of another module.
