Thanks for the replies. Compiling my code using:

g++ /home/robert/Desktop/test.c # uses c++ compiler
Instead of:

Produced no errors, and an output file called 'a.out', so I guess that means g++ keeps tabs on the libraries better.
g++ links to the C++ library; gcc does not.
I think you problem might be that you have C++ code in a .c file.
(IIRC, gcc/g++ chooses the frontend based on the file extension.) Try
.cpp .cc .C or .cxx instead.
doesn't matter, at least for c vs. C, cpp:
[wolfram:~] andreast% cat hello2.c
#include <iostream>
#include <string>
using namespace std;
int main ()
{
cout << "Hello World!\n"; // prints Hello World!
cout << "I'm a C++ program\n"; // prints I'm a C++ program
return 0;
}
[wolfram:~] andreast% g++ hello2.c
[wolfram:~] andreast% ./a.out
Hello World!
I'm a C++ program
better would be:
[wolfram:~] andreast% g++ -Wextra -Wall -o hello2 hello2.c
[wolfram:~] andreast% ./hello2
Hello World!
I'm a C++ program
