Invalid memory access

   Invalid memory access
-int *a; // This declares a as an integer pointer, meaning a can point to a memory address which contains an int
-\*a = 5; //Makes the content of the address pointed to by a 5. But a is not pointing to any valid address (int *a assigns garbage value to a) and hence this assignment can cause segmentation fault
