а.
Takes an object as an argument and adds a new key that is twice the value of the maximum of the old keys.
O b. Takes an object as an argument, loops through the entries of the object, and if the value of the entry is numeric, doubles it and
returns the modified object.
О с.
Creates an array of type "number" and sets each array element to be twice the value of the previous element.](https://content.bartleby.com/qna-images/question/cc2e6b79-1f48-4c40-b6f8-4e5fcdb801ee/be85d97e-c384-4fb2-aac2-e0149f679028/3fp5nix_thumbnail.png)

For the name of the class, use your initials from your name. The MYString objects will hold a cstring and allow it to be used and changed. We will be changing this class over the next couple programs, to be adding more features to it (and correcting some problems that the program has in this simple version). Your MYString class needs to be written using the .h and .cpp format. Inside the class we will have the following data members: Member Data Description char * str pointer to dynamic memory for storing the string int cap size of the memory that is available to be used(start with 20 char's and then double it whenever this is not enough) int end index of the end of the string (the '\0' char) The class will store the string in dynamic memory that is pointed to with the pointer.
