List of common C/C++ program segmentation fault causes

The main causes of segmentation faults are accessing uninitialized memory, memory beyond the scope of the program, or attempts to modify string constants. These may cause a segmentation fault, but are not guaranteed to do so. Here are some common causes of segmentation faults:

• Access out of array range
• Dereference null pointer
• Dereference freed memory
• Dereferencing an uninitialized pointer
• Incorrect use of "&" (taking address) and "*" (dereferencing) operators
• Incorrect formatting specifiers in printf and scanf statements
• Stack overflow
• Write to read-only memory
