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,
I am having two variables
IP="10.150.12.1"

To get network number, I know that a bitwise & will help.
networkno=IP & netmask
My code is

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:

wmemcmp
wmemcmp(3C) Standard C Library Functions wmemcmp(3C)
NAME
wmemcmp - compare wide-characters in memory
SYNOPSIS
#include <wchar.h>
int wmemcmp(const wchar_t *ws1, const wchar_t *ws2, size_t n);
DESCRIPTION
The wmemcmp() function compares the first n wide-characters of the object pointed to by ws1 to the first n wide-characters of the object
pointed to by ws2. This function is not affected by locale and all wchar_t values are treated identically. The null wide-character and
wchar_t values not corresponding to valid characters are not treated specially.
If n is zero, ws1 and ws2 must be a valid pointers and the function behaves as if the two objects compare equal.
RETURN VALUES
The wmemcmp() function returns an integer greater than, equal to, or less than 0, accordingly as the object pointed to by ws1 is greater
than, equal to, or less than the object pointed to by ws2.
ERRORS
No errors are defined.
