    here is my program's output given below

    Enter the size of an array: 2
    Your array size is 2
    Your array of size 2 is created
    Enter element to be inserted: 27

    Enter element to be inserted: 1
    Your 1 element is 27
    Your 2 element is 1
    Your memory block is destroyed

    Here is program given above which implement the variable size array
    I used one constructor and six member function.
    Each function has different work e.g.for displaying value,for creating array etc.
    I used comments also in program to make it clearly readable.
    I used one object and from that I accessed all the member function of the class intern.
    I hope you like my program and I get the chance to internship in your company for enhancing my knowledge and experience.
    THANK YOU for your consideration.
