A segmentation fault generally points to a memory address error - usually caused by overrunning an array, in my experience. Try compiling with a -C option (for most compilers this enables array boundary checking) and see if it gives you any information when the program crashes.

Just compile ur code using -g option eg $gcc -lm -g test.c
and then do $gdb a.out $gdb run Mostly program will crash, then type $gdb where It will show u the location of problem in ur code. Regards Sandip Jadhav -- http://www.aero.iitb.ac.in/userpages/sandipj |
