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
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
Run your C++ Program using the following command
g++ first.cpp -o test
./test
Output should show as follows
Hello World!

There is no need for being root, when editing your source code. So, call gedit WITHOUT sudo.
Cheers,

karl@ubuntu:~$ g++ first.cpp -o test
first.cpp:5: error: stray ‘\357’ in program
first.cpp:5: error: stray ‘\243’ in program
first.cpp:5: error: stray ‘\271’ in program

the c++ didn’t work for me
karl@ubuntu:~$ g++ first.cpp -o test
first.cpp:5: error: stray ‘\357’ in program
first.cpp:5: error: stray ‘\243’ in program
first.cpp:5: error: stray ‘\271’ in program
first.cpp: In function ‘int main()’:
first.cpp:4: error: expected primary-expression before ‘|’ token
first.cpp:5: error: ‘end’ is not a member of ‘std’
karl@ubuntu:~$ ./test
bash: ./test: No such file or directory

Never call your test program “test”. There is already a system utility called “test”. If you run “test” instead of “./test” you’ll have endless hours of fun:-)
“”"first.cpp:5: error: stray ‘\357’ in program”"”
looks like non-ASCII characters in your source file. Did you use a wordprocessor to edit it by any chance?
“”"first.cpp:5: error: ‘end’ is not a member of ‘std’”"”
it’s “endl”, not “end”. Note the trailing “eL” for end-line.

It would be better if you use gcc compiler instead of cc.

Akshar, cc is gcc on *buntu.

now it worked using this:
#include
using namespace std;
int main()
{
cout<<”HEY, you, I’m alive! Oh, and Hello World!\n”;
cin.get();
}

Damn. Using Windows compilers, like Borland 3.11 or Builder is more easier… Need more practice, I think.
