Try replacing your "pluses" with "narrow beams".
Code:#include <stdio.h> int main(void) { printf("2 + 2 = %d\n", 2 + 2); return 0; }
You're annoying me just fyi.
Code:#include <iostream> int main() { std::cout << "5 + 7 = " << (5+7) << "\n\n"; std::cout << "5 | 7 = " << (5|7) << "\n\n"; std::cout << "5 - 7 = " << (5-7) << "\n\n"; std::cout << "5 &~ 7 = " << (5&~7) << "\n\n"; }

lol, oh damn, i wanted to know what the technical term for the '|' was, and when I typed it in to google, the page went blank!?! ...gah, it won't return any results at all.
I guess it's a 'bar'... ?
my friend says 'pipe', cool. alright.
I believe the technical name is "vertical bar".
Pipe is what it's used for when chaining commands together in a shell/command prompt, e.g. find -name "*.c"|xargs grep printf|wc -l, which will show how many lines of "printf" there are in the .c files recursively the current directory.

See Wikipedia for the name:
I use vertical bar, and I'll understand you if you said pipe. (I'd give you odd looks for "Sheffer stroke" though.) "vertical bar" would probably be the most understood.The name of the character (|) is the Sheffer stroke, though often referred to as a pipe (by the Unix community) and Vertical bar, verti-bar, vertical line or divider line by others.
Broken bar (¦is a separate character.
Although if you're dealing with code, you might want to use the name of the operation (binary OR) and not "vertical bar".
long time; /* know C? */
Unprecedented performance: Nothing ever ran this slow before.
Any sufficiently advanced bug is indistinguishable from a feature.
Real Programmers confuse Halloween and Christmas, because dec 25 == oct 31.
The best way to accelerate an IBM is at 9.8 m/s/s.
recursion (re - cur' - zhun) n. 1. (see recursion)
Having just taken a Unix Programming course and learned how cool pipes are, I now refer to it as a pipe, even though it's not.
One is a addition operator and one is a bitwise or operator, quite different by any opinion.
Heh. Not a very good title for a thread eh?
I've also noticed that '*' = '+', lol
for example
yet, if I replace + with *,Code:2 + 2 = 4
OMG!Code:2 * 2 = 4
</sarcasm>
bitwise operators == logical operators which are the fundamental bases to mathematical operations (in computing)!
| = OR
& = AND
! = NOT
^ = XOR
They can be mixed and mingled to create all operations in mathematics, and physically* are. If you learn some engineering you'll see all mathematics, multiplication, division, etc etc are logical operations!
examples:
T | F = T
T & F = F
!T = F
T ^ F = T
(you can substitute T = 1, and F = 0)
http://en.wikipedia.org/wiki/AND
http://en.wikipedia.org/wiki/OR
http://en.wikipedia.org/wiki/XOR
http://en.wikipedia.org/wiki/NOT_gate
there's more, like NAND and such... which -all- can be mimic'd with c++ operators, and all can perform multiplication and all other mathematical operations.
while they themselves are -not- identical, they can perform identical functions. and do. there *really* is no such thing as '+' (plus) or '-' (minus), or any other of the 'higher level operations'.... go ahead and research it.
