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.

Hi,
I am trying to reverse a string using the following program utilizing the Exclusive OR bit operation:
int main() {
char str = "Quraish";
char *p = str, temp;
char *q = str + strlen(str) - 1;
while ( p != q ) {
if (*p != *q) {
*p ^= *q; *q ^= *p; *p ^= *q;... (1 Reply)
Hello guys,
should be a very easy questn for you:
I need to delete strings in file1 based on the list of strings in file2.

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

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:

string::shellquote
ShellQuote(3) User Contributed Perl Documentation ShellQuote(3)NAME
String::ShellQuote - quote strings for passing through the shell
SYNOPSIS
$string = shell_quote @list;
$string = shell_quote_best_effort @list;
$string = shell_comment_quote $string;
DESCRIPTION
This module contains some functions which are useful for quoting strings which are going to pass through the shell or a shell-like object.
shell_quote [string]...
shell_quote quotes strings so they can be passed through the shell. Each string is quoted so that the shell will pass it along as a
single argument and without further interpretation. If no strings are given an empty string is returned.
If any string can't be safely quoted shell_quote will croak.
shell_quote_best_effort [string]...
This is like shell_quote, excpet if the string can't be safely quoted it does the best it can and returns the result, instead of dying.
shell_comment_quote [string]
shell_comment_quote quotes the string so that it can safely be included in a shell-style comment (the current algorithm is that a sharp
character is placed after any newlines in the string).
This routine might be changed to accept multiple string arguments in the future. I haven't done this yet because I'm not sure if the
strings should be joined with blanks ($") or nothing ($,). Cast your vote today! Be sure to justify your answer.
EXAMPLES
$cmd = 'fuser 2>/dev/null ' . shell_quote @files;
@pids = split ' ', `$cmd`;
print CFG "# Configured by: ",
shell_comment_quote($ENV{LOGNAME}), "
";
BUGS
Only Bourne shell quoting is supported. I'd like to add other shells (particularly cmd.exe), but I'm not familiar with them. It would be
a big help if somebody supplied the details.
