hi everyone !

plz help me out on this simple program i m trying to run. actually its my first compilation on my newly installed kde 4.1 and i havent explored linux much !

editor :- KWrite

program :-

#include<iostream>
using std::cout;
using std::endl;

int main()
{
	cout<<"Hello, world!"<<endl;
}

when i compile it , i get this errors :-

jayant@linux-ana9:~/Documents> gcc -o hello_world hello_world.cpp
/tmp/cc9zBrFd.o: In function `main':
hello_world.cpp:(.text+0x1c): undefined reference to `std::cout'

Call the compiler as g++ or c++, otherwise it thinks you are compiling a C program.
