How do I fix segmentation fault in C?
It can be resolved by having a base condition to return from the recursive function. A pointer must point to valid memory before accessing it.
What is segmentation fault error in C?
A common run-time error for C programs by beginners is a “segmentation violation” or “segmentation fault.” When you run your program and the system reports a “segmentation violation,” it means your program has attempted to access an area of memory that it is not allowed to access.
Why do I keep getting segmentation fault?
A segmentation fault (aka segfault) is a common condition that causes programs to crash; they are often associated with a file named core . Segfaults are caused by a program trying to read or write an illegal memory location.

Where the segfault occurs is generally only a clue as to where “the mistake which causes” it is in the code. The given location is not necessarily where the problem resides. Note that where the segfault occurs is generally only a clue as to where “the mistake which causes” it is in the code.

What is the reason for segmentation fault?
The main reason for segmentation fault is accessing memory that is either not initialized, out of bounds for your program or trying to modify string literals . These may cause a segmentation fault though it is not guaranteed that they will cause a segmentation fault. Here are some of the common reasons for segmentation faults −

What is the definition of “segmentation fault”?
In computing, a segmentation fault (often shortened to segfault) or access violation is a fault , or failure condition, raised by hardware with memory protection, notifying an operating system (OS) the software has attempted to access a restricted area of memory (a memory access violation).
