Lexical Analysis in Compiler Design - Learn about Lexical Analysis, its importance in Compiler Design, and how it processes source code into tokens.
This is done by a compiler. A compiler is thus a fundamental tool for software development. Lexical analysis, as the first step of compilation, has an important role and should be performed in an optimal way. But not only compilers rely on lexical analysis....

In the expression parsing component, the limitations of StreamTokenizer were reached, and some analysis of the implications of those limits was provided. Understanding both StringTokenizer and StreamTokenizer and applying them will save you time and effort in your Java programming. In the example, ...

HLA v1.x's lexer, for example, was written using the LEX/FLEX language. HLA v2.x's lexical analyzer was written in assembly language (HLA). Although HLA v2.x's lexer isn't written in the most hand-optimized form, it is often an order of magnitude (or better) faster than HLA v...
