Factorials are hard to compute especially by using recursion , I believe changing the return value may increase your range of computability but otherwise stack overflow will lead to segmentation failure. try first compile program, use gcc file1, file2 and ./a.out its work for me. i have the same problem when run program by press run button.

If it shows Segmentation fault (core dumped) then follow following steps. This is free software: you are free to change and redistribute it.
Segmentation fault occur when you try to access memory that is not available for you. It could be practically everything and in general case needs a lot of debugging. There are a …
27.10.2015 · See AU: What is a segmentation fault? post and also this post which have some examples how reproduce it, SO: What is segmentation fault?. The simplest description I can come with (may be not the perfect): The program tried to access a memory area out side its own section. Operating system blocks it.
02.11.2019 · If your file contains a "word" (sequence of characters which are not whitespace) longer than 256 characters (maybe the text is in German, or the text of Mary Poppins), fscanf will write that many characters into word, overflowing it. This can lead to segmentation faults.
Nov 03, 2019 · This can lead to segmentation faults. You can prevent that by limiting the number of characters fscanf will try to write: fscanf (fp,"%256s",word); This may split a "word" into two or more parts, but only the last part with the dot will be counted (unless the word looks like "twohundred-and-fifty-five-characters.some-more").

Your Best Way to Fix Segmentation Faults On Linux Your most foolproof method of fixing segmentation faults is to simply avoid them. This may not always be an option, of course. If you’re running packaged software or applications that you have downloaded from the internet or provided by a friend or business associate, you may be out of luck.
Segmentation faults are commonly referred to as segfaults. There are four common mistakes that lead to segmentation faults: dereferencing NULL, dereferencing an uninitialized pointer, dereferencing a pointer that has been freed (or deleted, in C++) or that has gone out of scope (in the case of arrays declared in functions), and writing off the end of an array.
Step 1: Cause the segfault inside GDB · Step 2: Find the function call that caused the problem · Step 3: Inspect variables and values until you find a bad pointer ...
Feb 16, 2021 · Another way to detect segmentation faults is to look for core dumps. Core dumps are usually generated when there is a segmentation fault. Core dumps provide the situation of the program at the time of the crash and thus we will be able to analyze the crash. Core dumps must be enabled on most systems as shown below.

Omitting the "&" can cause a segmentation violation. Accessing beyond the bounds of an array: Make sure that you have not violated the bounds of any array you are using; i.e., you have not subscripted the array with a value less than the index of its lowest element or greater than the index of its highest element.
