I have come across something that I did not expect to find. I was trying
to print out a special character to the terminal and got a response other
that what I expected. The code I used was:
main()
{
union
{
char full_message;
int _message;
}u;
u.full_message = 0xaa;
printf("%10x\n", (int)u.full_message);
printf("%10x\n", u._message);
}
What I got when I ran this was:
ffffffaa
aa000000
I have tried various other methods for doing this to no avail.
When I tried to print the number as an integer, it worked as expected.
Does anyone know what I am doing wrong, or help me to understand why I got
this response.
