This is an example in Fortran how to make a function:
program hello
implicit none
integer:: square
integer:: i
Print *,"write your number:"
read *, i
print *,"your number:",i
i= square(i)
print *,"your result:",i
end program Hello
integer function square( a )
implicit none
integer :: a
square = a*a
end function square
Result:
write your number: 4 your number: 4 your result: 16
This is a little Program written in C sharp with Mono, It reads a number from the Terminal multiplies with itself and then print back:
using System.IO;
using System;
class Program
{
static void Main()
{
Console.Write("write your number: ");//Info text
String str = Console.ReadLine();//read input
Console.WriteLine("your number: "+str);//print input
int i = Convert.ToInt32(str);//convert to intager
i = i*i;//calculate
Console.WriteLine("your result: "+i);//print result
}
}
To compile run this:
mcs *.cs -out:main.exe
And then start with Mono :
mono main.exe
our result looks like this:
write your number: 4 your number: 4 your result: 16
The same Programm in Java is here : Java input output example
This is a little example about try and catch in Java:
public class HelloWorld{
public static void main(String []args){
System.out.print("write your number: ");//Info text
String str = System.console().readLine();//read input
int res = 0;
try{
res = Integer.parseInt(str);
res *= 2;
}catch (Exception e){
System.out.println("Error:"+e);
}
System.out.println("result:"+res);
}
}
Output looks like:
sh-4.3# java -Xmx128M -Xms16M test
write your number: 2
result:4
sh-4.3# java -Xmx128M -Xms16M test
write your number: a
Error:java.lang.NumberFormatException: For input string: "a"
result:0
This program calculates the sum from 10 numbers, you could hit “stop” to break and calculate less than 10 numbers:
public class HelloWorld{
public static void main(String []args){
int[] values = new int[10];
int i = 0;
int sum = 0;
System.out.print("write up to 10 numbers !\n");//Info text
for(i = 0; i <= values.length-1;++i){
System.out.print("write your number: ");//Info text
String str = System.console().readLine();
if(!str.equals("stop")){
values[i] = Integer.parseInt(str);//read input
}else{--i;break;}
}
System.out.print("your input:\n");//Info text
for(int x = 0; x <= i;++x){
System.out.print("your number: "+values[x]+"\n");//Info text
sum += values[x];
}
System.out.println("your result: "+sum);//print result
}
}
Output looks like this:
write up to 10 numbers ! write your number: 1 write your number: 2 write your number: 3 write your number: stop your input: your number: 1 your number: 2 your number: 3 your result: 6
I wrote a little script in Perl to shuffle Arrays or strings:
sub myshuffle {
my @str = ($#_ == 0)?split(//o, $_[0]):@_;
my $r1 = 0;
my $r2 = 0;
for(0..($#str*2)){
$r1 = int(rand($#str+1));
$r2 = int(rand($#str+1))while($r1 == $r2 && $#str>4);
($str[$r1],$str[$r2]) = ($str[$r2],$str[$r1]);
}
return join '', @str;
}
This are my examples:
print myshuffle("abcdefghijklmonopqrs").$/;
print myshuffle(1,2,3,4).$/;
print myshuffle(1,2,3).$/;
print myshuffle(1,2).$/;
and we got his as result:
obrdekohnlicgsfqapjm 2431 231 21
This is a little example in Java how to print an info text and then read a number from the terminal, calculate the square and then print the result:
public class HelloWorld{
public static void main(String []args){
System.out.print("write your number: ");//Info text
String str = System.console().readLine();//read input
System.out.println("your number: "+str);//print input
int i = Integer.parseInt(str);//convert to intager
i = i*i;//calculate
System.out.println("your result: "+i);//print result
}
}
To compile your test.java file run this in your terminal:
javac test.java
now we have the file test, to execute run this:
java -Xmx128M -Xms16M test
This is the output:
write your number: 4 your number: 4 your result: 16

This is an collection of problems and bugs I had with Backtrack 5 R2 (Linux based Distribution).
To download Backtrack look at http://www.backtrack-linux.org/downloads/
Ubuntu software centre and update manager
For more Software, I installed the ubuntu software centre with this command:
sudo apt-get install software-center
then run a update:
sudo apt-get update && apt-get dist-upgrade
now you could choose your software sources at:
System > Administration > Software Sources
If you want the Update manager, run this:
sudo apt-get install update-manager
Or you could add the ubuntu repository to your system, just open the “/etc/apt/sources.list” file and generate a list from http://repogen.simplylinux.ch/generate.php, now you could add what you want.
NVIDIA or ATI/AMD driver
NVIDIA: http://www.nvidia.de/Download/indexsg.aspx?lang=de
just run it from your download folder.
ATI/AMD: http://support.amd.com/us/gpudownload/Pages/index.aspx
Code:
sudo sh amd-driver.run --buildpkg Ubuntu/lucid sudo dpkg -i fglrx*.deb sudo aticonfig --initial -f
After a reboot you could check your driver status with:
fglrxinfo
Network
If you need more features at your network just install what you need:
network-manager-openvpn – network management framework (OpenVPN plugin core)
network-manager-openvpn-gnome – Network Management framework (OpenVPN plugin GNOME GUI)
network-manager-pptp – network management framework (PPTP plugin)
network-manager-pptp-gnome – network management framework (PPTP plugin)
network-manager-vpnc – network management framework (VPNC plugin core)
network-manager-vpnc-gnome – network management framework (VPNC plugin GNOME GUI)
network-manager – network management framework daemon
network-manager-dev – network management framework (development files)
network-manager-gnome – network management framework (GNOME frontend)
sudo apt-get install network-manager-openvpn sudo apt-get install network-manager-openvpn-gnome sudo apt-get install network-manager-pptp sudo apt-get install network-manager-pptp-gnome sudo apt-get install network-manager-vpnc sudo apt-get install network-manager-vpnc-gnome sudo apt-get install network-manager sudo apt-get install network-manager-dev sudo apt-get install network-manager-gnome
Add the Network icon to the panel:
echo auto lo > /etc/network/interfaces echo iface lo inet loopback >> /etc/network/interfaces service network-manager start nm-applet &
network is blocked
To solved this run this:
sudo rfkill unblock all
