Double any element's value that is less than controlValue. Ex: If controlValue = 10, then dataPoints = {2, 12, 9, 20} becomes {4
Aleksandr [31]

Answer:

import java.util.Scanner;

public class StudentScores

{

public static void main(String[] args) {

 Scanner scnr = new Scanner(System.in);

 final int NUM_POINTS = 4;

 int[] dataPoints = new int[NUM_POINTS];

 int controlValue;

 int i;

 controlValue = scnr.nextInt();

 for (i = 0; i < dataPoints.length; ++i) {

     dataPoints[i] = scnr.nextInt();

 }

 for (i = 0; i < dataPoints.length; ++i) {

     System.out.print(dataPoints[i] + " ");

 }

 System.out.println();

 for (i = 0; i < dataPoints.length; ++i) {

     if(dataPoints[i] < controlValue){

         dataPoints[i] = dataPoints[i] * 2;          

     }

     System.out.print(dataPoints[i] + " ");

 }

}

}

Explanation:

*Added parts highligted.

After getting the control value and values for the array, you printed them.

Create a for loop that iterates through the dataPoints. Inside the loop, check if a value in dataPoints is smaller than the contorolValue. If it is, multiply that value with 2 and assign it to the dataPoints array. Print the elements of the dataPoints

Fix the regular expression used in the rearrange_name function so that it can match middle names, middle initials, as well as do
marysya [2.9K]

Answer:

name = re.search(r"^([\w \.-]), ([\w \.-])$", list_name)

Explanation:

Regular expression is used to simplify the mode in which items in a data structure are for. It uses wildcards as shortcuts.

The python module for regular expression is 're'. The import statement is used to get the module and the search() method of the module is used to get the one matching item while the findall() method is used to get a list of all the matching items in a data structure.

The internet and the World Wide Web were results of years of research by Pioneers such as Ray Tomlinson, Vincent Cerf, Vannevar
iren [92.7K]

Answer:

The Internet began as a US Department of Defense network named Advanced Research Project Agency Network (ARPANET) funded by the Advanced Research Project Agency (ARPA, later DARPA). In the 1970s, universities and other educational institutions began sharing this technology. The network grew as more and more users began sharing information.However, the information being shared on this network was very limited because of its government ties. The ARPANET was decommissioned in 1990. This move was followed by the commercialization of the Internet, which allowed it to carry business and personal traffic.

Write a C++ program to grade the answers to a true-false quiz given to students in a course. The quiz consists of 5 true-false q
Eddi Din [679]

The quiz program is an illustration of loops and conditional statements

  • Loops are used to perform repetition
  • Conditional statements are used to make decisions

<h3>The quiz program</h3>

The quiz program written in C++, where comments are used to explain each action is as follows:

#include <iostream>

using namespace std;

int main(){

   //This prints the instruction

   cout<<"Enter T/t for True; F/f for False\n";

   //This initializes the question

   string questions[5] = { "Q1", "Q2", "Q3", "Q4", "Q5"};

   //This initializes the correct options

   char options[5] = { 'T','T','F','F','T'};

   //This declares the user response

   char opt;

   //This initializes the score to 0

   int score = 0;

   //This loop is repeated 5 times

   for (int i = 0; i < 5; i++){

       //This prints the current question

       cout << i + 1 <<". "<<questions[i]<<"\nAnswer: ";

       //This gets the user response

       cin>>opt;

       //If the user response is correct

       if(toupper(opt) == options[i]){

           //The score is incremented by 2

           score+=2;

       }

   }

   //This prints the total score

   cout<<"Score: "<<score;

   return 0;

}

Define a function below called process_grades. The function takes one argument: a list of integers. Each integer in the list cor
stealth61 [152]

Answer:

Following are the code in the Python Programming Language.

#define function

def process_grades(std_grades):

 result = []   #list type variable

 for grades in std_grades:   #set for loop

   if 90<=grades<=100:    #set if statement

     lettersGrade = 'A'   #variable initialization

   elif 80<=grades<=89:   #set elif statement

     lettersGrade = 'B'   #variable initialization

   elif 70<=grades<=79:   #set elif statement

     lettersGrade = 'C'    #variable initialization

   elif 60<=grades<=69:     #set elif statement

     lettersGrade = 'D'    #variable initialization

   else:    

     lettersGrade = 'F'    #variable initialization

   result.append(lettersGrade)     #append the value of lettersGrade in result

 return result      #print the value of the variable result

print(process_grades([90, 85, 85, 72]))   #call the function

Output:

['A', 'B', 'B', 'C']

Explanation:

Here, we define the function "process_grades" and pass an argument in the parameter list is "std_grades" in which we pass the grades of the students.

Then, we set the list data type variable "result" i9n which we store the grades of the students.

Then, we set the for loop and pass the condition.

Then, we set the "if-elif" statement and pass the conditions as given in the question.

Then, we append the value of the variable "lettersGrade" in the variable "result".

Finally, we call then function.
