Remaining Time: 35 minutes, 18 seconds,
¥ Question Completion Status:
A class named Account is defined as the following.
class Account
}
private:
int id;
double balance;
public:
//A constructor without parameter that creates a default account with id 0, balance 0
Account):
/A constructor with the parameter that setting the id and balance
Account(int, double),
int getId); / return the ID
double getBalance() //return the balance
void withdraw(double amount) // the amount will be withdrawn
void setlID(int), //set the ID
void setBalance (double) //set the balance
}:
Assume that we will create a separate file of implementation of the function definition for the questions a) -b)
a) Write a construction function definition with two parameters (ID and balance).
b) Write a function definition of the function declaration (void withdraw(double amount):).
c) Creates an Account object with an ID (1122) and balance ($20000). Then, write source codes to withdraw $2

A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…arrow_forwardIn a class with overloaded constructors, each version of the constructor must have a differentarrow_forward

- Circle Class (Easy) Write a Circle class that has the following member variables: radius : a double The class should have the following member functions: Default Constructor: default constructor that sets radius to 0.0. Constructor: accepts the radius of the circle as an argument. setRadius: an mutator function for the radius variable. getRadius: an accessor function for the radius variable. getArea: returns the area of the circle, which is calculated as area = pi * radius * radius getCircumference: returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius Step1: Create a declaration of the class. Step2: Write a program that demonstrates the Circle class by asking the user for the circle’s radius, creating Circle objects, and then reporting the circle’s area, and circumference.
