    [ integer <* <* (* float ) > > ] [ (* <* text > ) ] integer home, wxy; float whatever, a, b; text something; main () { home if( 1 == 1){ if( wxy == 123){ while(a1 < x7) { whatever } } } } home () { while(a > b) { if(123 != 456) { something } } } A New Design

13. jgs 564 00000111 Programming Assignment 02 • Only BINARY, DELIMITER,

    and OPERATOR are implemented. You will implement the rest of the required tokens (rules).

14. jgs 564 00000111 Ours Tokens Which tokens are needed for

    a programming language? a) Reserved words a) Special Symbols: Operators and delimiters a) Identifiers b) Literals or constants

15. jgs 564 00000111 Drafting a Lexer § Keywords = §

    Operator = § Delimiter = § ID =

16. jgs 564 00000111 Drafting a Lexer § Float = §

    Integer = § Hexadecimal = § Octal = § Binary = § String = § Char =
