I know this is staggeringly simple but I'm a raw recruit, I've typed this into Vim:-

#include <iostream>

using namespace std;

int choice;

int main(void)

{
cout << "\t\t\t\tEnter integer" << endl;
cin >> choice;
cout << "\t\t\t\tYOU ENTERED THE INTEGER" << choice <<endl;



return 0;

}

I type gcc -Wall untitled.cpp into the terminal and I get:-

untitled.cpp:10: error: expected primary-expression before ‘<<’ token
untitled.cpp:12: error: expected primary-expression before ‘<<’ token

Please put me out of my misery!

Also what should I put in the int main(void) line, my book just has () but it seems to cause problems so I copied the int main(void) from some code online and that seems ok. Is my book outdated?

Thanks in advance

I don't think there is anything wrong with your code but you are using the wrong compiler. For C++ code, you should use g++ instead of gcc, i.e.:

$ g++ -Wall untitled.cpp

Take out the spaces between < < and make it <<, which is a single operator.

edit:
Nevermind. Looks like they show up spaced apart with my screen font.

edit2:
Compilation works fine for me, though you get STL link errors when building with gcc. You need to use g++, but I don't know what's causing your problem. Maybe you've written this with a rich text editor and there's a hidden character in there? Copy and paste from your own post and see if it works then.

Thanks guys, using g++ sorted the problem.

What is the score with the main() function though, if I load an example from an ide there's stuff like'argc' something or other in there. Do I need to include these args or not?

Those arguments are how one passes command-line arguments. void is non-standard since it gives you no "startup options" for your program.

Build and run using various command-line arguments.
