Dear Varun,

Your question doesn't provide enough information for anyone to provide a 
useful answer.

Your best course of action is to use a debugger (e.g., lldb or gdb) to 
determine why your code is triggering a segmentation fault.  If you do 
that, you can figure out what pointer variable is pointing to NULL or to 
a bad memory location.  With that information, you can either fix the 
problem yourself or develop a more focused question that people will be 
able to answer.
