Following will show you bitwise And & , OR | and XOR ^ operations, And & will copy a bit to the result if it exists in both operands:
OR | will copy a bit if it exists in eather operand:
XOR ^ copies the bit if it is set in one operand (but not both)
Hi,
Is it possible to use bitwise operators in bit fields?
For example:
typedef struct Mystruct {
unsigned char A :1 ;
unsigned char B :1 ;
} Mystruct;
and assume
struct Mystruct STR_1S, STR_2S, tempSTRS = {0};
then the following line:
tempSTRS = STR_1S & STR_2S;
gives the... (3 Replies)
Hi !
How to reset a variable to 0 after a reset value, say 10 using bitwise
XOR.
For example,
int cnt=0;
if(cnt<10)
cnt++;
else
cnt = 0;
How can we achieve this by using XOR only.
thanks, (1 Reply)
I am taking an online course on Unix scripting. The topic is Unix arithmetic operators and the lesson is Logical and bitwise operations. It is not clear how much storage space Unix uses to represent integers that are typed. Bitwise negation caused me to question how many bits are used to... (3 Replies)
Hi
Suppose we have these code lines:
#define _IN_USE 0x001 /* set when process slot is in use */
#define _EXITING 0x002 /* set when exit is expected */
#define _REFRESHING 0x004

Hi,
I am having two variables
IP="10.150.12.1"
netmask="255.255.255.0"
To get network number, I know that a bitwise & will help.
networkno=IP & netmask
My code is
#!/usr/bin/ksh
ip="10.150.12.1"
netmask="255.255.255.0"
networkno="$ip" & "$netmask"
echo $networkno
I am... (7 Replies)
Hello All,
i have two 16 bit binaries that in two different variables, i want to perform a bitwise AND between the two and store the result in a different variable.
can anyone throw some light on doing this in a bourne shell...

The purpose of this article is revealing the unrevealed parts of the bitwise XOR.
As we aware, the truth table for the XOR operator is :
A B A^B
0 0 0
0 1 1
1 0 1
1 1 0
For example , 1^2 will be calculated as given below:
First the operands... (1 Reply)
please any one can suggest me how to use bitesie || opearator to do this
#initallize a=0 b=0
#condition
if then
a=0
else a=1
fi
#bitwise or opeartion b = a || b

Hello All,
I am writing basic state machine which maintains 8 different states and there is posibility that system may be in multiple states at a time (Except for state1 to state3. menas only once state can be active at a time from state1 to state3).
