Chapter 8.4, Problem 8.24CP
Program Plan Intro
String class:
- The “String” class would provide different methods that examines for a string inside of a string.
- The term “substring” refers to a string that denotes another string’s part.
- The “startsWith” method would determine whether calling string of object begins with a particular substring.
- The method returns “true” if string begins with specified substring, it returns “false” otherwise.
- The “endsWith” method would determine whether calling string would end with a specified substring.
- The method returns “true” if string ends with specified substring, it returns “false” otherwise.
- The “regionMatches” method would determine whether specified regions for two strings match.
- The first argument for this method could be “true” or “false” that indicates whether a case-insensitive comparison could be performed.
- The “replace” method substitutes occurrences of one character with another character.
StringBuilder class:
- The “StringBuilder” class is same as “String” class except that contents of “StringBuilder” objects could be changed.
- It provides numerous methods that “String” class does not have.
- The “append” method accepts an argument that might be a primitive data type.
- It appends a string representation to contents of calling object.
- The “insert” method accepts two arguments, an integer that specifies position in string of calling object as well as value to be inserted.
- The “replace” method substitutes occurrences of single character with another character.
- The “deleteCharAt” method removes character at specified position in sequence
- The “toString” method converts a “StringBuilder” object in to a regular string.
- The “replace” method replaces a specified substring with a string.

Description
In this assignment you will write a program that shows the valid moves of chess pieces. Your program will draw a board with 64 squares using the traditional layout, next ask the user to choose a move, and then, depending on the user's choice, redraw the board with the selected chess piece and its valid moves. Please see the examples of valid moves of chess pieces and the traditional chess board layout below:
At the beginning, your program should draw an empty chess board and prompt the user to enter a move:

- Practice / Frequency of Characters Write a method that returns the frequency of each characters of a given String parameter. If the given String is null, then return null If the given String is empty return an empty map Example input: output: empty map explanation: input is empty Example input: null output: null explanation: input is null. Since problem output is focused on the frequency we can comfortably use Map data structure. Because we can use characters as key and the occurrences of them as value.

- The friend function is incompatible with the goal of encapsulation. Also, talk about the many applications for the friend function that you have.arrow_forwardIn C++ yhou will create a new class named StringMod that will have several functions specific tostring. Here is a UML diagram:StringMod- str : string+ StringMod()+ StringMod(string);+ size() const : int+ backwards() const : string+ count(char) const : int+ getString() const : string+ uppercase() const : string+ lowercase() const : string+ erase() : void+ setString(string) : voidFirst of all, none of these functions should contain output statements! No cout, no cin, in any of thesefunctions!As you can see, several of the methods of StringMod are const, meaning they won’t change theinternal string. You’ll likely declare a local string which will be updated and then returned.The default constructor just sets str to an empty string, "". The constructor with parameters should justcall setString() to set str to the value passed to the constructor.backwards() returns a new string that is the reverse of the string in str.uppercase() takes every letter in the string and capitalizes it, while…arrow_forwardHow can you access values in string?arrow_forward
