Run c/C++ propgram in Ubuntu




Install C and C++ Compilers in Ubuntu

  • sudo aptitude install build-essential   /**** This will install all the required packages for C and C++ compilers ***/

Firstly compile the code using the following command

  • cc -c first.c

then create an executable using the following command

  • cc -o first first.c

Now run this executable using the following command

  • ./first


Compiling your first C++ program

If you want to run c++ program follow this procedure

g++ is the compiler that you must use.

you should use a .cpp file extension rather than a .c one

You need to create a file

  • sudo gedit “any filename”.cpp


Run your C++ Program using the following command

  • g++ first.cpp -o test
  • ./test

NS2 (NS-2.35) Installation in Ubuntu


This post will help you in installing Network Simulator 2 version NS2.35 in Ubuntu 11.10
• Install Ubuntu

  • Unzip or untar it to any folder (recommended is /home/loginname) using the following commands one by one
  • sudo apt-get update
  • sudo apt-get build-essential autoconf automake libxmu-dev
  • tar zxvf ns-allinone-2.35.tar.gz (simply you may extract manually )
  • cd ns-allinone-2.35
  • ./install
  • after that go through ubuntu’s software center and search “NS2 ” you will get “Discrete event simulator targeted at networking research ns2”  and once again install it.
