Chapter 16, Problem 23RQE
Explanation of Solution
Exception class data members:
In C++, a data can be stored in exception class members which can be passed back to an exception handler.
Example:
Consider the following class contains an exception class to handle an exception as follows:
// Class definition
class Square
{
// Access specifier
private:
// Variable declaration
int a;
// Access specifier
public:
// Exception Class definition
class Zerovalue
{
// Access specifier
private:
// Variable declaration
int x;
// Access specifier
public:
Zerovalue(int val)
{ x = val; }
double get_value() const
{ return x; }
};
// Function definition
void Square::set_value(in...

Instructions:
Exception handing
Add exception handling to the game (try, catch, throw). You are expected to use the standard exception classes to try functions, throw objects, and catch those objects when problems occur.
At a minimum, you should have your code throw an invalid_argument object when data from the user is wrong.
File GamePurse.h:
class GamePurse
{
// data
int purseAmount;
public:
// public functions
GamePurse(int);
void Win(int);
void Loose(int);
int GetAmount();
};
File GamePurse.cpp:
#include "GamePurse.h"
// constructor initilaizes the purseAmount variable
GamePurse::GamePurse(int amount){
purseAmount = amount;
}
// function definations
// add a winning amount to the purseAmount
void GamePurse:: Win(int amount){
purseAmount+= amount;
}
// deduct an amount from the purseAmount.
void GamePurse:: Loose(int amount){
purseAmount-= amount;
}
// return the value of purseAmount.
int GamePurse::GetAmount(){
return purseAmount;
}

Write a Month class that holds information about the month. Write exception classes for the following error conditions:• A number less than 1 or greater than 12 is given for the month number.• An invalid string is given for the name of the month.Modify the Month class so that it throws the appropriate exception when either of these errors occurs. Demonstrate the classes in a program.
Code that responds to exceptions when they are thrown and prevents the program from abruptly crashing is called a(n) __________.a. exit strategyb. fail safec. event handlerd. exception handler

- C++ PROGRAM EXCEPTION HANDLING Write a program with a function that accepts a string from user. The function prints “Valid String” only when the string contains at least one capital letter, one vowel, one integer and one ‘@’ character. An example of a valid string is @Developer123. If the user enters any operators like +,*,= then your program must throw a character exception. If the string contains any brackets like {[(}]), then your program must throw an integer exception. Write appropriate catch blocks of these exceptions.arrow_forwardC++ D.S. Malik Exercise 14-4 Write a program that prompts the user to enter time in 12-hour notation. The program then outputs the time in 24-hour notation. Your program must contain three exception classes: invalidHr, invalidMin, and invalidSec. If the user enters an invalid value for hours, then the program should throw and catch an invalidHr object. Follow similar conventions for the invalid values of minutes and seconds.arrow_forwardBriefly describe what an exception is.arrow_forward

Write a steps_to_miles() function that takes the number of steps as a parameter and returns the miles walked. The steps_to_miles() function throws a ValueError object with the message "Exception: Negative step count entered." when the number of steps is negative. Complete the main() program that reads the number of steps from a user, calls the steps_to_miles() function, and outputs the returned value from the steps_to_miles() function. Use a try-except block to catch any ValueError object thrown by the steps_to_miles() function and output the exception message. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print(f'{your_value:.2f}') The code I have so far(Python Code): import sysdef steps_to_miles(steps): try: if steps<0: raise ValueError('Exception: Negative step count entered.') return…arrow_forwardCalculator.java, is a simple command-line calculator.

The class should have two constructors, one of which should be the default function Object() { [native code] }. If the default function Object() { [native code] } throws an error, the function should return "Tornado: Take cover immediately!"
