Tokens are fundamental building blocks of a programming language. They represent specific units of meaning within a program, such as keywords, identifiers, operators, and literals. These elements are grouped together based on their syntactic relationships to form meaningful units.
Examples:
Keyword: int represents an integer variable.
Identifier: name represents a variable named "name".
Operator: = represents the assignment operator.
Literal: 5 represents a numerical value.
Benefits of understanding tokens:
Improved understanding: Tokens make it easier to understand the structure and meaning of a program by grouping related elements together.
Code generation: Tokens help the compiler generate the machine code necessary to execute the program.
Semantic analysis: Tokens allow the compiler to perform semantic analysis, determining the type and relationships between different elements in the program.
Further points:
A single token may belong to multiple categories, such as both identifiers and operators.
A program with a large number of tokens can be complex, but it is organized into a finite set of categories.
Tokens are the input for the parser, which translates the human-readable code into a data structure that can be processed by the compiler
