Solution
If a NULL pointer is dereferenced in C, it will cause a runtime error or crash. This is because a NULL pointer does not point to any valid memory location. Attempting to access such a location is undefined behavior in C, and most systems handle this by raising a segmentation fault, which typically causes the program to terminate abnormally.
