What will be displayed after the following code executes? (Note: the order of the display of entries in a dictionary are not in
iren [92.7K]

Answer:

Nothing will be printed

Explanation:

You can easily find out that FL is not a member of the Dictionary. And we are checking these in the if. Since the if condition ends up being false, the further process will not run as they will only if the condition ends up being true. Hence, nothing will be printed.

Remember, del is used to delete a dictionary item. If this would have been a true condition for if then the FL item in the dictionary would have been deleted as it, in that case, would have been present there. And then the next line would have again added the FL item, and print would have printed the dictionary items with FL item as well. However, since if the condition is ending up being false, nothing will be printed.

If cities['FL'] and print is outside if then

the output will be

{'FL': 'Tallahassee', 'GA': 'Atlanta', 'NY': 'Albany', 'CA': 'San Diego'}

Write a program that asks the user to enter an object’s mass, then calls a // function to return the object's weigh in newtown.
lisov135 [29]

Answer:

import java.util.Scanner;

public class num8 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter the mass");

       double mass = in.nextDouble();

       double weight = calWeight(mass);

       System.out.println("The weigth is "+weight);

   }

   static double calWeight(double mass){

       double weight = mass*9.80665; // assume a = accelation due to gravity = 9.80665N

       if(weight>500){

           System.out.println("Too Heavy");

       }

       else if(weight<100){

           System.out.println("Too Light");

       }

       return weight;

   }

}

Explanation:

  • Using Java programming language
  • The main method is created to request and store a variable, mass in kilogram. The main method call calWeight() and passes the value for mass
  • A method calWeight() is created that calculates the weight in newtons (mass * 9.8).
  • The method checks if the weight is greater than 500 (prints too heavy) if less than 100(prints to light)
  • Returns the weight

Write a program that writes 10 random numbers into a file named numbers using loops.
MariettaO [177]

Answer:

The program in cpp for the given scenario is shown below.

#include <stdio.h>

#include <iostream>

#include <fstream>

using namespace std;

int main()

{

   //object created of file stream

   ofstream out;

   //file opened for writing

   out.open("numbers.txt");

   std::cout << "File opened." << std::endl;

   //inside for loop, random numbers written to numbers.txt using rand()

   for(int n=0; n<10; n++)

   {

       out<<rand()<<endl;

   }

   //file closed

   out.close();

   std::cout << "File closed." << std::endl;

   return 0;

}

Explanation:

1. An object of the ofstream is created. The ofstream refers to output file stream. This is used to create file for write and append operations.

ofstream out;

2. The file named, numbers.txt, is opened using the open() method with the object of ofstream.

out.open("numbers.txt");

3. The message is displayed to the user that the file is opened.

4. Inside a for loop, which executes 10 times, a random number is generated. This random number is written to the file and a new line inserted.

5. The random number is generated using rand() method. Every number is written on  new line.

out<<rand()<<endl;

6. Every execution of the for loop repeats steps 4 and 5.

7. When the loop ends, the file is closed using close() method with the object of ofstream.

out.close();

8. A message is displayed to the user that the file is closed.

9. The header file, fstream, is included to support file operations.

10. The extension of the file can be changed from .txt to any other type of file as per requirement.

11. The program can be tested for writing more numbers to the file.

12. The program can be tested for writing any type of numeric data to the file.

13. The program is written in cpp due to simplicity.

14. In other languages such as java or csharp, the code is written inside classes.

15. In cpp, all the code is written inside main() method.

16.    The screenshot of the output messages displayed is attached.
