Can anyone fix this code I use Visual Studios The Errors im

Can anyone fix this code, I use Visual Studios:

The Errors im getting is that it is not reverseing correctly,

And the line if (arr[i] == strRev[i])

gives me a error code C4700 uninitialized local variable \'strRev\' used

This is the program that neeeds to be created:

In C++, with a myString.h, myStringImp.cpp, and main.cpp:

Design and implement a class myString:

-Use a dynamic array of char to store the characters of myString.

-Use an int to keep track of the length of myString.

-Provide a parameterized constructor that takes an initial string, a default constructor, destructor, assignment operator, and copy constructor. All need to correctly handle the dynamic array.

-Also provide these member functions:

--length() //the length of myString

--isEqual() //if it is equal to another myString

--print() //output to a terminal cout or outFile

--reverse() //reverse the order of characters in myString

--isPalindrome() //if myString reads the same after being reversed

Here is the code that is broken:

C++ Code:
