Rolling one dice isn't that exiting. Every side has the same chance. Now we want to roll two dice at the same time without writing the same code all over.
To do that, we use **functions**.

## Knowledge

Functions are like subprograms, which you can call. They look just like our main program.
You actually called functions before. Remember those more complex instructions like ``printf`` and ``rand``.
They were all functions.

The first thing you have to write, is the **return type**. The return type tells the computer, what kind of value you function calculates and returns.
For our dice example this would be an **int**. There are also functions which return nothing. In that case the return type is **void**.

Next comes the name. You can name your functions any name you like with a few restrictions.
After the name you write the **arguments** in parentheses. They also have a type and a name. The dice function doesn't need any arguments.
Between the curly braces comes your code. In the end you have to write **return** and behind that the value your function calculated.

Here is an example of a simple add function:

    int add(int a, int b)
    {
        return a+b;
    }

## Task

Your task is to implement the die function and call twice to simulate the rolling of two dice.
