- For LEX and YACC code create a new directory for each question and name the source files
lex.landyaac.yfor simplicity. The commands given below are tailored for the default names. &&simply combines the commands to a single line.
# To simulate LEX programs use
$ flex lex.l && gcc lex.yy.c -ll && ./a.out
# To simulate YACC programs use
$ yacc -d yacc.y && flex lex.l && gcc y.tab.c lex.yy.c -ll && ./a.out
# To simulate C programs use
