I'm having trouble accepting a string (actually a character array) as input.
Consider the following declaration:

In C++, I'm processing a string like follows:
using namespace std;

If you use getline() after cin >> anything, you must first flush the newline character from the buffer.
You can achieve this by using the cin.ignore()
It would be something like this:

When an object's static type is used to associate it with a member function, this is known as static binding (understand the type of its class).
When a pointer or reference is associated with a member function based on the dynamic type of the object, this is known as dynamic binding (understand the instance of the variable at runtime).
Before continuing, keep in mind that dynamic binding only works with pointers, references, and virtual functions for the base class.
Because everything needed to call the function is known at compile time, the first call is a static binding (also known as early binding).
Derived1 d1(1, 10);
You already know that the d1 instance is a Derived1 automatic variable, and that it will call the Derived1::display data method ().
The first condition is incorrect: d1 is neither a pointer nor a reference.
The second condition isn't acceptable:
There is no virtual Derived1::display data.
The second call is for
Calling a function by value copies the argument and stores it in a local variable for use by the function, so the argument is unaffected if the value of the local variable changes.
The argument is passed to the function as a reference rather than a copy, so if the function changes the value of the argument, the argument is also changed.
The void change(int); function prototype informs the compiler that there is a function named change that takes a single int argument and returns void (i.e. nothing).
Because there is no & with the argument, it is called by value.
You have the line change(orig); later in your code, which actually calls the function with.

A reverse function is integrated into C++ and can be used to reverse a string.
This function accepts two parameters:
The start iterator for the string
The string iterator has come to an end.
The following line of code demonstrates how to use this function:
