little vs. big endians

if the output is--

1 : the machine is little endian

2 : the machine is big endian

 

#include <stdio.h>

int main() {
    unsigned int x = 1;
    printf ("%d", (int) (((char *)&x)[0]));
    return 0;
}

We mentioned bit fields :

Jim showed some C examples of structs and style from his system course : http://cs.marlboro.edu/courses/spring2016/systems/code/c_word_list/

Dylan:

 $ make show_bytes
 $ xxd show_bytes   # show hex dump

Here's a link to some of my systems course notes on gdb :
