Now, that you can roll two dice at the same time, let's try to do some statistics.
|
||
|
|
For that we need a way do something multiple times. In programming these constructs
|
||
|
|
are called <b>loops</b>.
|

## Knowledge
|
||
|
|
|
||
|
|
Loops may seem to have a convoluted syntax, but once you got it, it is straightforward.
|
||
|
|
First comes the keyword <b>for</b>, followed by open and closed parentheses. Then you set up your counter variable,
|
||
|
|
the condition, under which you stay in the loop and the instruction, which gets executed at the end, between the parentheses.

Definition of the for-loop
|
||
|
|
<pre><code style="font-size:11px">for(initialization; condition; increment/decrement)
|
||
|
|
{
|
||
|
|
// Looped code
|
||
|
|
}</pre></code>
|
||
|
|
</p>
|
||
|
|
|
||
|
|
</div>
|
||
|
|
<div class="right">
|
||
|
|
<p>
|
||
|
|
Here is an example of a loop with 10 iterations:
|
||
|
|
<pre><code style="font-size:11px">for(int i = 0; i < 10; i=i+1)
|
||
|
|
{
|
||
|
|
printf("We are in the %d. iteration", i+1);
|
||
|
|
}</pre></code>
|
||
|
|
</p>
|
||
|
|
</div>
|
||
|
|
</div>
|
||
|
|
|
||
|
|
* int i = 0 is the initialization and gets executed once at the beginning. It sets the iteration counter to zero.
|
||
|
|
* i < 10 is the condition. This gets checked every iteration in the beginning. If it is not true we skip over the loop.
|
||
|
|
* i=i+1; is the increment. This gets executed at the end of every iteration. This counts our up the iteration counter by one. You can also write i++ to achieve the same result.

## Task
|
||
|
|
|
||
|
|
Your task is the average of 100 rolls.
