conceptual doubt in c programming similar question asked in gate 2018 but i have modified version please help someone

Question

Suppose this code was given  i tested using runing the code in compiler but i dont trust the compiler 

sir can u explain me little bit in depth ::

#include <stdio.h>
struct ournode {
char x,y,z;
};
int main()
{
struct ournode p={'1','0','a'+2};
struct ournode *q=&p;
printf("%c",*(short *)q);
printf("%c",*((short *)q+1));
return 0;
}

Comments

@mv_ind, That was correct.

Just a correction: structure instead of array. Remaining is correct only.

sir but  a pointer can point to an unknown memory location thats fine but when we try to accees it it may lead to runtime error

then sir how it correct

lets assume it is little endian:

for first printf

printf("%c",*(short *)q);

i know we can extract the bytes since its inside the struct

 

but for second printf

printf("%c",*((short *)q+1));

 the pointer respresentation get out of known memory location then how can we access it should'nt it may lead to runtime error

I mean that output depends upon little endian or big endian machine.  One is provide output where other may throw runtime error.
