Figure out the output of code ...

I'm having trouble with this assignment which I'm supposed to show what the output would be for this code:

Code:

---

int x=1;
int y=2;
int z=3;

printf("%d %d\n", 3 | 6, 3 || 6);

printf("%d %d\n", 6 >> 1, 6 << 1);

printf("%d %d\n", 10 & 3,10 && 3);

---

I'm confused because x, y, nor z is in any of the printf statements...
Am I missing something?

Thank you for any help

Well we don't really do your homework for you, what's the fun of that? Besides, you could always just compile it and run it! :rolleyes:

Break it down into pieces:

3 | 6 == what?
3 || 6 == what?
6 >> 1 == what?
6 << 1 == what?

See a pattern here yet?

If that's the assignment, then you're right, the variables x, y and z have no use being there. In fact if you compile this with "gcc -Wall" it tells you:

Code:

---

$ gcc -Wall test.c
test.c: In function `main':
test.c:6: warning: unused variable `x'
test.c:7: warning: unused variable `y'
test.c:8: warning: unused variable `z'

I understand that, what I meant to ask was where are x, y, and z being used it this code?

Is that the entire homework question, or are they used elsewhere? It could be they're like those word problems:

"If John is traveling from Chicago, and Mark is traveling from New York, where is Seattle?"

Where they give you useless information to confuse you.

Either that or you've only posted part of the code in question, and they're being used in some code you haven't shown us.

That is the entire code. I guess I will have to email my professor because everything I gave you is what is exactly what is given to me.

edit:
Assuming there is no typo and x,y,z are just useless info, then the output would just be:
7 1
3 12
2 1
