A template class named MyArray. 1) MyArray is a dynamic partially filled array for primitive types. 2) data members: a pointer for the array - any associated variables needed to manage the array. 3) Constructor must insure that specified capacity is possible.

OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Question
100%
C++
Hi, need help with the entirety of Question 1, need an explanation on "The Big Three" as well if possible (I hope this isn't too much to ask), thank you very much.
![1. Implement the following:
a. A template class named MyArray.
1) MyArray is a dynamic partially filled array for primitive types.
2) data members:
- a pointer for the array
- any associated variables needed to manage the array.
3) Constructor must insure that specified capacity is possible. Exit the program if
an illegal value is specified.
4) "The Big Three" are required to insure deep copy.
5) Private grow function is used to automatically increase the size of the array
when adding elements.
6) Add function to safely append elements to the array.
7) getSize function that returns the current number of elements.
8) Overloaded the [] operator to read and update existing elements.
Test using following main function.
int main() {
cout << endl;
MyArray<int> a(2);
for(int i=0; i<20; i++) {
a.add(i+1);
}
a.output();
MyArray<char> c(20);
for(int i=0; i<26; i++) {
c.add(static_cast<char>(i+65));
}
c.output();
cout << endl;
return 0;
}
Output from main function above:
Copy the previous program to a new file and implement the following:
1) A class SomeObj with a single integer id as a data member.
2) This class must have a default and user defined constructor.
3) Create an output function to display the id of the object.
4) Modify the MyArray class to create an array of SomeObj objects.
