why am i getting this wrong can anybody correct this?

Upload the workspace for H37 where you'll find the definition of the FlexArray class in h37.h. Do not make any changes to h37.h at all. As you can see in the header, you are going to write three member functions. Here are the descriptions: The readData Member Function The readData() member function will read integer data from an input stream (such as cin) until the user terminates input by either running out of data or by entering an in- valid value such as Q. The function sets the size data member to the number of numeric in- puts. The mernber data-is a pointer to a heap allocated array At the end of the function, the array should have exactly size-ele- ments. The function will return *this (a reference to the current FleArray object). elements the user will enter. Start with a ca- You won't know at the outset how many pacity of INITIAL CAPACITY (defined inside h37.h). Do not change this from its cur- rent value of 2. Managing Memory in readData Inside readData(), whenever your array fills up, create a new array of double the cur- rent capacity, copy the original elements to the new storage, free the original array and assign the new array to the member data_. At the end of your function, you'll follow a similar pattern to shrink the allocated memory so that it is exactly the same size as the number of elements. Be sure to delete any intermediate arrays. If you have any memory leaks displayed, fix them before submitting your assignment. This algorithm is similar to that used for fiLLArray) in In-Class Exercise 9B. The only difference is that reallocation and copying that occurs when the array is filled up The tostring Member Function For toString), the result should be delimited with braces "" and ")". The individ- ual elements in the array should be separated with a comma, followed by a space. There should be no space before the first element or after the last. (You'll recognize this as the fencepost algorithm we covered in In-Class Exercise 9B.) You can convert the integer elements in the array by using the to string() function in the header Upload the workspace for H37 where you'll find the definition of the FlexArray class in h37.h.
