You are working on a graphical app, which includes multiple different shapes. The given code declares a base Shape class with an

abstract area() method and a width attribute. You need to create two Shape subclasses, Square and Circle, which initialize the width attribute using their constructor, and define their area() methods. The area() for the Square class should output the area of the square (the square of the width), while for the Circle, it should output the area of the given circle (PI*width*width). The code in main creates two objects with the given user input and calls the area() methods.
Sample Input:
5
2

Sample Output:
25
12.566370614359172

The area of the square is 5*5=25, while the area of the circle is PI*2*2=12.566370614359172

cellPhoneBill(m,tx)Write the function cellPhoneBill()that takes two int m and txas input and returns a float.The function takes
lidiya [134]

Answer:

The solution code is written in C++

  1. float cellPhone(int m, int tx){
  2.    float COST_PER_MIN = 0.1;
  3.    float COST_PER_MESSAGE = 0.2;
  4.    
  5.    float bill_amount = m * COST_PER_MIN + tx * COST_PER_MESSAGE;
  6.    
  7.    return bill_amount;
  8. }

Explanation:

Firstly, declare a function named cellPhone() that takes two input parameters, m and tx (Line 1).

Since the policy of the carrier company is not given in the question, I make a presumption that the cost per minutes is $0.10 and the cost per message is $0.20 (Line 2- 3).

Next, apply the formula m * COST_PER_MIN + tx * COST_PER_MESSAGE to calculate the total bill (Line 5) and return the bill_amount as function output (Line 7).
