I am learning C and I want to access(just to see what is inside the address, for fun actually.) content in specific address in C like:

```
char *p = (char *)0x7ffeefad7be8;
printf("%s",*p);

```

but it show segmentation fault. I know that part of memory is 
reserved and can not be access, the space for kernal, e,g. But I think that the address is accessable since it is the address which I got from this code:

```
int *p,a;
p = &a;
printf("%p",p);

```

So it is suppose to be inside range of [heap] and [stack].(It is separated with the first code and just proved the address is accessable)

But the error just keep reporting! I did a lot of trying and researching, though it still doesn't work.

Here is the output of `$cat /proc/self/maps`:

I really want to figure out why it doesn't work because i have spent hours on trying. Thanks!
