Lex- Collect Tokens and sort

Hello friend,   Here I am with an interesting Lex program which sorts all the nubers from input file and sort them. If you are well-familiarised with lex paradigm, it is very easy task. Things to remember: The definition [0-9]+ can detect all the numbers from input The number detected at present will be pointed by yytext and have length yyleng Whenever a new token (here a number) is detected, yytext will be replaced with new value.  Logic Read the input If a number is detected, store it in an array (we can use yytext and yyleng for this). Read each digit --> multiply with 10 --> add next digit -->continue upto last digit.   for eg, to read 123 initialise num=0; read 1--> num=num*10+1-->num=0+1-->num=1 read 2--> num=num*10+2-->num=10+2-->num=12 read...

Lex and Yacc in Windows 7 - Compile and Run

Hi Friend, I was in search for a long time to get a platform in windows-7 to run lex and Yacc ,for academic purposes. Many of my friends also had the same problem and often forced to choose Linux only for merely executing Lex & Yacc programs..!!! At last, I found one solution and its my pleasure to share it with all of you.!!  :) Its very simple.You need to download two very small files. You have to download two executable( i.e.,   .exe files). In total,its size may have about 370KB. To download them click the links below. Link 1:   Flex Link 2:  Bison Save both files in same place....
