Sheer curiosity: having the main loop run to NF-1 only might yield a fraction of a percent run time reduction:
Unfortunately, replacing the
by
increases run time dramatically, probably because the ++ operation is a register operation while the other is a full addition.
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

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).

XScreenSaver(1) General Commands Manual XScreenSaver(1)NAME
squiral - square spirals screensaver
SYNOPSIS
squiral [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-noinstall] [-visual
visual] [-fill percent] [-count number] [-delay usec] [-disorder fraction] [-handedness fraction] [-cycle]
DESCRIPTION
The squiral program displays interacting, spiral-producing automata
OPTIONS
squiral accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
-mono If on a color display, pretend we're on a monochrome display.
-install
Install a private colormap for the window.
-visual visual
Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.
-fill percent
Specify the percent (0-100) of the screen which must be filled before the screen is cleared. 60-80 percent are good values.
-count number
The number of squiralies. By default, the screen width divided by 32.
-delay usec
The wait between steps. The default is 1000.
-disorder fraction
The fraction of the time a squiraly will choose a new direction. The default is 0.005.
-handedness fraction
The fraction of the time a squiraly will choose to enter lefthanded mode. 0.0 means exclusively right-handed behavior, 0.5 (the
default) is a balance between the two, and 1.0 is exclusively left-handed behaviour.
ENVIRONMENT
DISPLAY to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
BUGS
