How Do I Fix Segmentation Fault in Linux?

What causes a segmentation fault in Linux?

Segmentation faults can arise from similar conditions. A buffer overflow, such as trying to reach outside the bounds of an array, can cause a segfault, or trying to access memory that has not been allocated or has been deleted. Trying to write to memory that is read-only can also cause a memory error.
