• Download Labl17_q2.cpp from Canvas. Read the given code. The Arr class's purpose is to
store and perform operations on an array. In C++, a basic array doesn't keep track of its own
size. That's why when we pass an array to a function, we often pass an accompanying integer.
• The Arr class we implement will hold the array as well as perform operations on the array such
as "filling" the array with a stated value.
• When we declare an array, we specify its datatype. We can have arrays of integers, arrays of
strings, etc. Because we can have arrays of many distinct types, we will implement our Arr
class as a class template.
template <typename T, int LENGTH>
The first template parameter T refers to the datatype of the array. The second parameter LENGTH
refers to the array's maximum number of elements.
Arrcint, 5> myIntArr;
Arrestring, 4> myStrArr;
• The first statement creates an int array called myIntarr with a capacity of 7 elements. When
this templated class is created, T will be an int and LENGTH (always an int) will be 7.
• The second statement creates a string array called myStrarr with a capacity of 3 elements.
When this templated class is created, T will be a string and LENGTH (always an int) will be 3.
The class declaration and the main test client are provided. Your task will be to implement the
