Topic: Lexical Analysis You are supposed to implement lexer (lexical Analysis). Role of lexer is to remove extra spaces, comments from given code. It completely scans the code and generates tokens from source code. You are supposed to implement lexer on your purposed syntax. In start of your program you have to present sample token. C++ language has following tokens. > Keywords > Identifiers > Constants > Strings Operator After generation of token check whether given token is valid or not for example if you have generated a token for identifier, match identifier with its rules if it does not follow the rules move token to error list. In your program you have to implement a class name Lexer that should implement above functionality which generates tokens and invalid tokens. Consider a statement int a; Tokens for above statements are [if int is not keyword list it should be moved to error list] [match rules for identifier on "a" if it matches its valid other wise move to error list] You can use C# or C+ language for implementation.

Topic: Lexical Analysis
You are supposed to implement lexer (lexical Analysis). Role of lexer is to remove extra spaces,
comments from given code. It completely scans the code and generates tokens from source code.
You are supposed to implement lexer on your purposed syntax. In start of your program you
have to present sample token. C++ language has following tokens.
> Keywords
> Identifiers
> Constants
> Strings
> Operator
After generation of token check whether given token is valid or not for example if you have
generated a token for identifier, match identifier with its rules if it does not follow the rules move
token to error list.
In your program you have to implement a class name Lexer that should implement above
functionality which generates tokens and invalid tokens. Consider a statement int a;
Tokens for above statements are
<int, keyword> [if int is not keyword list it should be moved to error list]
<a,identifier>
[match rules for identifier on “a" if it matches its valid other wise
nove to error list]
You can use C# or C+ language for implementation.
