I want to compute the bitwise number of matches in pairwise fashion for all columns. The problem is I have 18486955 rows and 750 columns. Please help with code, I believe this will take a lot of time, is there a way of tracking progress?
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
...

Dear all
I have a large file w. ~ 10 million lines.
The first two cols have matching partners.
For example:
A A
A B
B B
or
A A
B A
B B
The matches may be separated by an unknown number of lines.
My intention is to group them and add a "group" value in the last col.

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

set_menu_format
menu_format(3CURSES) Curses Library Functions menu_format(3CURSES)NAME
menu_format, set_menu_format - set and get maximum numbers of rows and columns in menus
SYNOPSIS
cc [ flag... ] file... -lmenu-lcurses [ library... ]
#include <menu.h>
int set_menu_format(MENU *menu, int rows, int cols);
void menu_format(MENU *menu, int *rows, int *cols);
DESCRIPTION
set_menu_format() sets the maximum number of rows and columns of items that may be displayed at one time on a menu. If the menu contains
more items than can be displayed at once, the menu will be scrollable.
menu_format() returns the maximum number of rows and columns that may be displayed at one time on menu. rows and cols are pointers to the
variables used to return these values.
RETURN VALUES
set_menu_format() returns one of the following:
E_OK The routine returned successfully.
E_SYSTEM_ERROR System error.
E_BAD_ARGUMENT An incorrect argument was passed to the routine.
E_POSTED The menu is already posted.
