I am trying to reverse a string using the following program utilizing the Exclusive OR bit operation:
The above code works perfectly alright, but if I change the line
to
(I am trying to do swapping inline)
it prints an empty string. Could anyone tell me why this behaviour is?
i posted a reply the other day and needed an answer to this question while i was clarifyiing a few matter.. "how to compare to date variable in string format without having to compare word for word"..

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)
Hi,
What is the difference in the following two awk one-liners?
awk -F, '{s++} END {if (s == 1 && $4 > "09:10:00") {print $2, $4}}' f1
awk -F, '{s++} s == 1 && $4 > "09:10:00" {print $2, $4}' f1
Even though, all the 2nd column values have duplicate records, the first code does not give any... (4 Replies)
Hi,

Hi,
In the below C code,
#include <stdio.h>
void print() {
printf("Hello\n");
}
int main() {
void (*f)() = (void (*)()) print;
f();

}
I wonder, how the syntaxes "f()" and "(*f)()" are treated as same without any error? Is this an improvement or ANSI/ISO... (1 Reply)
I am aware of truth table for XOR between binary values .
Out of curious in would like to know how XOR works between 2 strings which contain alphabets .
For example A ^ B
How it works internally?
Please help me to understand this
Thanks (1 Reply)
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)

PAPS(1) General Commands Manual PAPS(1)NAME
paps - UTF-8 to PostScript converter using Pango
SYNOPSIS
paps [options] files...
DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
through the pango ft2 backend.
OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is
included below.
--landscape
Landscape output. Default is portrait.
--columns=cl
Number of columns output. Default is 1.
--font=desc
Set the font description. Default is Monospace 12.
--rtl Do rtl layout.
--paper ps
Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.
--bottom-margin=bm
Set bottom margin in postscript points (1/72 inch). Default is 36.
--top-margin=tm
Set top margin. Default is 36.
--left-margin=lm
Set left margin. Default is 36.
--right-margin=rm
Set right margin. Default is 36.
--help Show summary of options.
--header
Draw page header for each page.
--markup
Interpret the text as pango markup.
--encoding=ENCODING
Assume the documentation encoding is ENCODING.
--lpi Set the lines per inch. This determines the line spacing.
--cpi Set the characters per inch. This is an alternative method of specifying the font size.
--stretch-chars
Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
behaviour.
