Installing ns-3.37 and ns-3.35 in Ubuntu | Ubuntu 22.04 | NS3

Multiple Versions of ns3 in Ubuntu 22.04 In this post, we are going to install two versions of ns3 namely ns-3.35 and ns-3.37  My OS is : Ubuntu 22.04 LTS (Long Term Support) ns-3.35 uses waf and (./waf --run scratch/first)  ns-3.37 uses cmake  (./ns3 run scratch/first.cc) So we will install both the packages  Go through the video for complete instructions To start with  $ sudo apt update  $ sudo apt install build-essential autoconf automake libxmu-dev g++ python3 python3-dev pkg-config sqlite3 cmake python3-setuptools git qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools gir1.2-goocanvas-2.0 python3-gi python3-gi-cairo python3-pygraphviz gir1.2-gtk-3.0 ipython3 openmpi-bin openmpi-common openmpi-doc libopenmpi-dev autoconf cvs bzr unrar gsl-bin libgsl-dev libgslcblas0 wireshark tcpdump sqlite sqlite3 libsqlite3-dev  libxml2 libxml2-dev libc6-dev libc6-dev-i386 libclang-dev llvm-dev automake python3-pip libxml2 libxml2-dev libboost-all-dev  I have downloaded both the versions of ns3 fr

Sorting Functions in PHP

There are different sorting functions used to sort the arrays and other variables. Some of the their functions are listed below:

sort() – used to sort an array in normal order

rsort() – used to sort an array in normal reverse order

asort() – used to sort array and maintain the index association(key value pair maintains even after sorting)

arsort() – same as asort() but in reverse order

ksort() – used to sort an array by its keys….

Example Program

<?php

$fruits[0]=”Orange”;

$fruits[1]=”Mango”;

$fruits[2]=”Banana”;

print_r($fruits);

sort($fruits);

print_r($fruits);

?>

The above script displays the fruits array in normal order and also in sorted order…. simply replace the sort function with other sort functions and may see the results.

for key value, change the fruits array like the following script

$fruits=array(10=> “Orange”, 100=> “Mango”, 1000=>”Banana”);

and use the functions ksort, asort and arsort () and see that the key value pair is unchanged…..
