Why not you use gdb debugger for finding out segmentation fault or the line where your code is failing. There are many other videos on youtube for any help related to gdb.

In order to recieve help you provide link to the question you are trying to solve and the code which you have written. use ideone.com (or any similar website) for sharing the code.
