Kindly mention the Cases

What are the conditions or scenarios under which one may get Segmentation fault in C programming language? If someone could mention this I will take care while coding my C program.

Segmentation fault in occurs mainly when a memory area that is not allowed to be accessed is tried to be used.

For example if you have a C code as below placed in a memory protected platform:

char *a = "Example";
*a = 'T';


Then on compilation of the above program you would get segmentation fault as the Example string was tried to be placed in area of memory marked as read only.
