I have a program which will write informations like gid,gname,resname,restype,etc... in a file.I wrote a function to get the starting and ending position of a particular group.Stating of a particular group (say group 12)is denoted in a file by #gid12 and the end of the group is denoted by @gid12.I don't know wat mistake i have done. The code works correctly only for the 1st group in the file. when i try to get other groups information i am getting wrong output.Plz tel me wat is the bug in my program.And is there any other way to find the starting and ending position of a particular group from my file.

OUTPUT FILE WILL LOOK AS FOLLOWS:

IP_Address:12.12.12.12
#gid1:sdf
Res-info$:;xyz;qww;qasddfasd;2:
Res-info$:;hjuy;asdfv;dfhvhvf;3:
Res-info$:;asdfg;eretg;wedsfh;7:
@gid1
IP_Address:123.12.132.12
#gid2:dfc
Res-info$:;hjuy;asdfv;dfhvhvf;3:
Res-info$:;asdfg;eretg;wedsfh;7:
@gid2
IP_Address:121.121.112.12
#gid12:xsdf
Res-info$:;xyz;qww;qasddfasd;2:
Res-info$:;asdfg;eretg;wedsfh;7:
@gid12

I have given the code below.Is there any other way to get the starting and ending position of a particular group from my file?? kindly help me on this

please stop double posting your question.

you will not get twice the number of answers. you will, in all likelihood, get fewer answers because people find double posters to be annoying.
