Hi Gurus,
I wrote a small KSH script, in that i am comparing two variables like this
curr_time = date +%h.%m
set_time=23.55
If ];
then
zip the file
fi
The above script is croned to run evey 5(3,8,.......,58) minutes, but it is zipping at 23.03 hours. My intention is at 23.58 .what... (4 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)
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)
Hi,
I'm trying to work on the script given below

As highlighted , when i pass $smp19 as parameter ,it does not display the output.However when i try giving "Hi" instead... (2 Replies)

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)

devel::trace
Trace(3pm) User Contributed Perl Documentation Trace(3pm)NAME
Devel::Trace - Print out each line before it is executed (like "sh -x")
SYNOPSIS
perl -d:Trace program
DESCRIPTION
If you run your program with "perl -d:Trace program", this module will print a message to standard error just before each line is executed.
For example, if your program looks like this:
#!/usr/bin/perl
print "Statement 1 at line 4
";
print "Statement 2 at line 5
";
print "Call to sub x returns ", &x(), " at line 6.
";
exit 0;
sub x {
print "In sub x at line 12.
";
return 13;
}
Then the "Trace" output will look like this:
>> ./test:4: print "Statement 1 at line 4
";
>> ./test:5: print "Statement 2 at line 5
";
>> ./test:6: print "Call to sub x returns ", &x(), " at line 6.
";
>> ./test:12: print "In sub x at line 12.
";
>> ./test:13: return 13;
>> ./test:8: exit 0;
This is something like the shell's "-x" option.
DETAILS
Inside your program, you can enable and disable tracing by doing
$Devel::Trace::TRACE = 1; # Enable
$Devel::Trace::TRACE = 0; # Disable
or
Devel::Trace::trace('on'); # Enable
Devel::Trace::trace('off'); # Disable
"Devel::Trace" exports the "trace" function if you ask it to:
import Devel::Trace 'trace';
Then if you want you just say
trace 'on'; # Enable
trace 'off'; # Disable
TODO
o You should be able to send the trace output to the filehandle of your choice.
o You should be able to specify the format of the output.
o You should be able to get the output into a string.
We'll see.
