Explain why a C++ program would use the statement

```
Array workerList{100};
```

When creating class-template specializations from a class template, it is necessary to provide a type (or possibly several types) to complete the definition of the new type being declared. For example, when creating an "array of Employees" from an Array class template, the type Employee is provided to the class template to complete the definition of an array of Employees. In this case, the number of Employees is known in advance.
