Problem with #include

Hello,

In my source i include a file tat holds all the includes and
some functions and voids.
Now when my header file named "test.h" has this:

#include <iostream>

void something()
{
cout << "Im printing something" << endl;
}

And i compile it with my source, Im getting error messages
with the void in my header file that are pointing out that
"#include <iostream>" isn't even being used in the header file
I can use it in my source, but not in the header file???
What am i doing wrong?

Don´t really understand what you mean. From where I can se you are trying to compile a header file??? In c++ you cannot compile header files just source files.

you can't have code/functions in a header file, just definitions of things.

So in test.cpp you will have a function

Code:

---

void print()
{
  cout << "something" << endl;
}

---

and in test.h

you just have the prototype of the print function so

Code:

---

void print();

---

(this is my header file)

#include <iostream>

void bla()
{
cout << "bla"; // I can't do this!
}

void bla2()
{
printf("bla"); // But i can do this ?1
}


I'ts like it isnt using iostream in the functions in the header file

(im not compiling the header file, im including it in my source)

You need to have this line:

Code:

---

using namespace std;

---

under #include <iostream>

If not then each call to cout needs to read:

Code:

---

std::cout<<"words"<<endl;

---

DOH! Of course , sorry i forgot
