Code to read a character in the file

hi,

i need a code that can read a character in the file. The example file is like this:

Quote:

---

The quick brown fox,,,
field 1, 344
request: 12344 fjsdlfkj
bit 1
bit 2
fields2
response fkljsdfljewir
bit 1
bit 2
bit 3
successfull
request
bit 1
bit 2
response
failed

---

Then, i will read that file(above) and then get the request word until before the response. Then get the response until before the word successful.

But my code below only shows per line basis not per word or character. :( please help me.

Sample output is like this:

request: 12344 fjsdlfkj

bit 2
fields2

response fkljsdfljewir
bit 1
bit 2
bit 3

hi. thank you for welcoming me.


yup, thats the output.

i just need to get the request data and its response.

Hello Truffy,

Does this application need to be generic? Will it support other text files in the same request/response format or will you only be dealing with the example above?

it will support other extension files. that program is reading server logs, meaning it is in tail, i just listen
to the file and if there is another transaction, i will get it again and parse it. do you think that file reader is the
best approached to that project? the server logs is on the back end, and i will make a front end logs. c++ linux is our
back end. one of my friend told me that i can used java using ssh but i cant figure out how to do it.
