In C#, loops are called iteration statements. We need to master both, recursion and loops. There are 3 kinds of loops in C# :
- while and do (...) while
- for
- foreach
## While loop
```cs
while (<condition>)
{
	// repeat stuff
}
```
The ``condition`` is a boolean
**Example**
```cs
unit SumWhile(unit n)
{
	uint loop = 0;
	while (n > 1)
	{
		loop += 1;
		n = n - 1;
	}
	return loop;
}
```
