Answer:

Codes are given below:

Explanation:

Since the language is not specified, I am writing it in c++

1) Ask the user to input an integer. Print out the next three consecutive numbers.

#include <iostream>

 using namespace std;

 int main()    //Start of main function

{

  int number;  

   cout << "Enter your number<<endl;

  cin >> number;     //this will take your number as an input

 

  cout <<"The next three numbers are: " << number + 1 << endl;

  cout << number + 2 << endl;

   cout << number + 3 << endl;  

  return 0;

}   //End of main function

2) Write a program that accepts three decimal numbers as input and outputs their sum.

#include <iostream>

 using namespace std;

 int main()    //Start of main function

{

  int number1, number2, number3;  

   cout << "Enter your three numbers<<endl;

  cin >> number1 >> number2>> number3 ;     //this will take your three number as an input

 

  cout <<"The sum of three numbers are: " << number1 + number2+ number3 <<  endl;  

  return 0;

}   //End of main function

The code is written using Python language as it is one of the programming languages introduced by the Edhesive courses.

Answer (Question 1):

  1. num = int(input("Input an integer: "))
  2. for i in range(1, 4):
  3.    print(num + i)

Explanation (Question 1):

<u>Line 1 : </u>

Prompt user for input an integer.  In Python we can easily use <em>input </em>method to ask user for an input.

However the default data type of the input is a string and therefore we need to enclose our input value within <em>int()</em> to convert the value from string to integer.

<u>Line 3 - 4:</u>

Create a for-loop to loop though the code in Line 4 for three times using the <em>range() </em>function. The <em>range(1, 4) </em>will return a list of numbers, [1, 2, 3] .

In each round of the loops, one number from the list will be taken sequentially and total up with the input number, num and display using <em>print()</em> function.

Answer (Question 2):

  1. counter = 3
  2. sum = 0
  3. while (counter > 0):
  4.    num = float(input("Enter a decimal number: "))
  5.    sum += num
  6.    counter = counter - 1
  7. print("The sum is " + str(sum))

Explanation (Question 2):

<u>Line 1 - 2 :</u>

Create a <em>counter</em> variable and a <em>sum</em> variable and initialize them with 3 and 0, respectively.

<u>Line 4:</u>

Create a <em>while </em>loop and set a condition while counter is bigger than zero, the loop should keep running the code from Line 5-7.

<u>Line 5:</u>

Use <em>input</em> function again to prompt user for a decimal number. This time we need to use<em> float </em>function to convert the input value from string to decimal data type.

<u>Line 6:</u>

Every time when a decimal number is input, the number is added to the <em>sum</em> variable.

<u>Line 7:</u>

Decrement the counter variable by 1. This step is important to ensure the while loop will only be repeated for three times and each loop will only accept one input value from user.

<u>Line 9</u>

Display the sum.

You created an interactive application named GreenvilleRevenue. The program prompts a user for the number of contestants entered
Korolek [52]

Answer:

Explanation:

The program in this code is written correctly and has the messages applied in the code. Therefore, the only thing that would need to be done is pass the correct integers in the code. If you pass the integer 100 contestants for last year and 300 for current year. Then these inputs will provide the following output as requested in the question.

The competition is more than twice as big this year!

This is because the current year would be greater than double last years (100 * 2 = 200)
