Pointer initialisation gives segmentation fault

Question

I wrote a C program as follows:

CASE 1

int *a; /* pointer variable declaration */

int b; /* actual variable declaration */

*a=11;

a=&b;/* st         


        

Answer 1

int a stores a random integer value. So saying by saying *a, you might be accessing a memory location that is out of bounds or invalid. So it is a seg fault.
