Question

please can any1 check my code..... it runs into an infinite loop
it is to delete duplicate records in a file

Answer 1

@A.Avinash_Goutham you have used while loop here right?

Answer 2

yup
but that to make sure that it keeps on asking

Answer 3

because it is not incremented
look the value is initialized as int i = 0 ;
but u havent used i++ here
so value remains 0 always
thats y condition remains false
well i know java dont know C++ :)

Answer 4

ther's a user menu in there -.-

Answer 5

hmmmm

Answer 6

wait so what is really the problem here so i can understand it

Answer 7

run that code

Answer 8

oh srry i dont know how to do that

Answer 9

um there's an infinite loop

Answer 10

how come

Answer 11

First of all you have to find a code style.Your code looks so chaotic, i cannot read it :P

Answer 12

The problem was on the function fileAdd, you tried to read students name in some weird way i have never seen before, anyway.. try getting string input by scanf("%s",&mystring); and you 'll be fine ;)

Answer 13

i tried to store them in a structure.....

Answer 14

no i tried changing it....that's not the problem

Answer 15

fine there was a problem with scanf for name.........oh sry u mentioned it @infinity_ but the prob with %s is it stops reading after white space so i used %[^/n]

Answer 16

ther's a segmentation fault in dupDelete()

Answer 17

you can try reading it char by char and ignore spaces

Answer 18

yeah.. i saw the segmentation fault, just check you memory allocation, there must be something with it

Answer 19

i donno how to check them...

Answer 20

you make a copy of your file and start removing things till you stop getting seg fault, then you try to recover things you have removed and try to find where the seg fault occurs.You can also try using a debugger, but, at least for me, manual debugging works better

Answer 21

ok i l do it....

Answer 22

No, pleaaasseee don't guess and check to find segfault causes. Haha. Learn to use gdb. Learn to love gdb.

Answer 23

@farmdagnation for small programs such this gdb is not needed.It's kinda stupid actually to use gdb for 50 lines of code...
