Notes

• Oru karyam ondu maximum ee programs run cheythu nokkane Errors okke eppozha vandiyum vilichu varunnathu ennu parayan pattathilla
• Ee programs run cheyyumbol enthenkilum Sambhavichal athinte utharavathi ithu cheytha njan alla ennu ariyichu kollunnu😁

How to run

Program having both LEX and YACC programs

bison -d fileName.y  
flex fileName.l        
gcc lex.yy.c y.tab.c -o calcn ## YACC inte program run cheyyumbol y.tab.c generate aakunundengil ee command use cheyyaam allengil (fileName.tab.c) ennu use cheyyane
./calc

Program with only LEX file

lex fileName.l
gcc lex.yy.c
./a.out

Program with only C Code

Prathyekichu parayandallo 😎 Engaanum Maranittundengil ithaane

gcc fileName.c
./a.out
