I want to test C++ on Ubuntu 9.04.
So, follow this post from www.ubuntugeek.com. This post said that………
If you are a developer you need C and C++ Compiler for your development work. In Ubuntu you can install the build-essential for C and C++ compilers.
Install C and C++ Compilers in Ubuntu
sudo aptitude install build-essential
This will install all the required packages for C and C++ compilers
Testing C and C++ Programs
-
Compiling Your first C Programs
Now you need to open first.c file
sudo gedit first.c
add the following lines save and exit the file
#include <stdio.h>
int main()
{
printf(“Hello, World!\n”);
return 0;
}
Firstly compile the code using the following command
cc -c first.c
that would produce an object file you may need to add to the library.
then create an executable using the following command
cc -o first first.c
Now run this executable using the following command
./first
Output should show as follows
Hello, world
-
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 first.cpp
add the following lines save and exit the file
#include <iostream>
int main()
{
std::cout << “Hello, World!” << std::endl;
return 0;
}
Run your C++ Program using the following command
g++ first.cpp -o test
./test
Output should show as follows
Hello World!
And I test on my Toshiba laptop.

But, I test with this code only for C++ which is the same above. 
#include<iostream>
using namespace std;
int main()
{
cout << “Hello, World!” << endl;
return 0;
}
