What is a symbol table in C++?

Prerequisite: Symbol Table. A Symbol table is a data structure used by the compiler, where each identifier in program’s source code is stored along with information associated with it relating to its declaration. It stores identifier as well as it’s associated attributes like scope, type, line-number of occurrence, etc …

How do you implement symbol table in C++?

A Symbol table is a data structure used by the compiler, where each identifier in program’s source code is stored along with information associated with it relating to its declaration….Symbol Table for above code:

Name	Type	Scope
add	function	global
a	int	function parameter
b	int	function parameter
sum	int	local

How do symbol tables work?

In computer science, a symbol table is a data structure used by a language translator such as a compiler or interpreter, where each identifier (or symbol) in a program’s source code is associated with information relating to its declaration or appearance in the source.

What is the significance of symbol table?

Symbol Table is an important data structure created and maintained by the compiler in order to keep track of semantics of variables i.e. it stores information about the scope and binding information about names, information about instances of various entities such as variable and function names, classes, objects, etc.

What role does symbol table play in compiler?

Symbol table is an important data structure created and maintained by compilers in order to store information about the occurrence of various entities such as variable names, function names, objects, classes, interfaces, etc. Symbol table is used by both the analysis and the synthesis parts of a compiler.

What is in the symbol table associated with the name of an object?

An object file’s symbol table holds information needed to locate and relocate a program’s symbolic definitions and references. A symbol table index is a subscript into this array.

How do you implement a symbol table?

The symbol table can be implemented in the unordered list if the compiler is used to handle the small amount of data. A symbol table can be implemented in one of the following techniques: Linear (sorted or unsorted) list. Hash table.

What is the use of symbol table in compiler design Mcq?

Explanation: Both the analysis and synthesis components of a compiler use the symbol table. i) To keep all of the names of all entities in one place in a systematic format.

Which phase of compiler does use symbol table?

The information in the symbol table is entered in the lexical analysis and syntax analysis phase, however, is used in later phases of compiler (semantic analysis, intermediate code generation, code optimization, and code generation).
