Chapter 11: Problem 20

Write a program that reads in five amounts of money, doubles each amount, and then writes out the doubled values to the screen. Use one array with Money as the base type. Hint: Use Display 11.9 as a guide, but this program will be simpler than the one in Display 11.9

Question: Create a program that reads in five amounts of money, doubles each amount, and writes out the doubled values on the screen. Answer: To create a program that reads in five amounts of money, doubles each amount, and writes out the doubled values on the screen, follow these steps: 1. Declare an array of size 5 with a money base type named `money_values`. 2. Use a loop to read in five amounts of money from the user and store them in the `money_values` array. 3. Use another loop to double each value in the `money_values` array by multiplying it by 2. 4. Use another loop to display the doubled values of the `money_values` array on the screen.

Step by step solution

01

Declare an array of size 5

Declare an array of size 5 with the money base type. Let's name this array `money_values`. You may use the appropriate syntax for the language you are working with to declare the array.
02

Read in five amounts of money

Use a loop (for loop or while loop) to read in five amounts of money from the user and store them in the `money_values` array. Make sure to prompt the users for input, and validate the input if necessary.
03

Double the amounts

Using another loop, go through each element in the `money_values` array and double its value by multiplying it by 2. Store the result back in the corresponding element of the array.
04

Display the doubled values

Finally, use another loop to iterate through the `money_values` array and display the doubled values on the screen. Make sure to format the output so it is easily readable by the user. That's it! With these steps, you should be able to create a program that handles the tasks specified in the exercise. Keep in mind that the actual implementation may vary depending on the programming language you are using.

If a class is named MyClass and it has a constructor, what is the constructor named? If MyClass has a destructor, what is the destructor named?

What is the difference between a (binary) operator and a function?

Here is a definition of a class called Pairs. Objects of type Pairs can be used in any situation where ordered pairs are needed. Your task is to write implementations of the overloaded operator >> and the overloaded opera- tor << so that objects of class Pairs are to be input and output in the form (5,6) (5,-4) (-5,4) or (-5,-6). You need not implement any constructor or other member, and you need not do any input format checking. #include using namespace std; class Pairs { public: Pairs( ); Pairs(int first, int second); //other members and friends friend istream& operator>> (istream& ins, Pairs& second); friend ostream& operator<< (ostream& outs, const Pairs& second); private: int f; int s; };

The following is the first line of the copy constructor definition for the class StringVar. The identifier StringVar occurs three times and means something slightly different each time. What does it mean in each of the three cases? StringVar::StringVar(const StringVar\& string_object)

What are the differences and the similarities between a call-by-value parameter and a call-by-const-reference parameter? Function declarations that illustrate these are: void call_by_value(int x); void call_by_const_reference(const int & x);
