You also need to sort out how your code looks. I'd indent the brackets and cout so it's more indented than the if statement. Same goes with the Pause, make it so it's the same place as return 0;.
Also annotate the fuck out of everything. May sound stupid now but you really need to get practicing with everything you do.

something like this:
| Code: |
#include <iostream>
#include <string>
using namespace std;
int main()
{
string x;
cout <<"Enter password : \n\n";
cin >> x;
if(x == "blahblahblah")
{
cout <<"12345";
}
system("PAUSE");
return 0;
}

| I'm pretty sure you need to add the header to the included directories.

You need to give that function a body! All you've done there is give it a signature.
| Code: | int add(int x, int y)
{
return x + y;
} |
Then you can
| Code: | #include <iostream>
#include "add.h"
int main(int argc, const char * argv[])
{
std::cout << add(1, 2) << std::endl;
} |
(You're compiler should make main() return something AUTOMATICALLY)

With the 'std::'. Say I had a cin before cout, would I need to put std:: before them both?

Yes, anything in the standard c++ library will need std:: before it in you don't add using namespace std. This is good in big projects, because you can write your own namespace with the same function names and be able to distinguish between them.
std::cout and mynamespace::cout, for example, might do TOTALLY different things
Example for the add function:
| Code: | #include <iostream>
namespace example
{
int add(int x, int y)
{
return x + y;
}
}
int main (int argc, const char * argv[])
{
std::cout << example::add(1, 3) << std::endl;
} |
You should declare namespaces in some header file and give them a counterpart .cpp file though and they can span over various source files. Declaring functions within namespace xxx {} will add them to that namespace no matter what file it is in
