If you fail a course as a MAIN (residency) course, you can repeat that course as either a MAIN (residency) or an online (IG or IIG) course. True False

Answers

Answer: False

Explanation:

The statement that "you fail a course as a MAIN (residency) course, you can repeat that course as either a MAIN (residency) or an online (IG or IIG) course" is false.

It should be noted that if one fail a course as a residency course, the course can only be repeated as a main (residency) course and not an online course. When a course is failed, such course has to be repeated the following semester and this will give the person the chance to improve their GPA.

Consider the following class in Java:

public class MountainBike extends Bicycle {
public int seatHeight;
public MountainBike(int startHeight,
int startCadence,
int startSpeed,
int startGear) {
super(startCadence, startSpeed, startGear);
seatHeight = startHeight;
}

public void setHeight(int newValue) {
seatHeight = newValue;
}
}
What is this trying to accomplish?

super(startCadence, startSpeed, startGear);

a. Four fields of the MountainBike class are defined: super, startCadence, startSpeed and startGear.
b. The constructor for the parent class is called.
c. A method of the MountainBike class named super is defined.
d. Three fields are defined for the MountainBike class as intances of the class named super.

Answers

Answer:

b. The constructor for the parent class is called.

Explanation:

In this case this specific piece of code is calling the constructor for the parent class. Since a MountainBike object is being created. This creation uses the MountainBike class constructor but since this is a subclass of the Bicycle class, the super() method is calling the parent class constructor and passing the variables startCadence, startSpeed, startGear to that constructor. The Bicycle constructor is the one being called by super() and it will handle what to do with the variables inputs being passed.

The function should return -1 if the items are in ascending order, 0 if the items are unordered, and 1 if the items are in descending order. The program reads four items from input and outputs if the items are ordered. The items can be different types, including integers, strings, characters, or doubles. Ex. If the input is:

Answers

Answer:

Explanation:

The following code was written in Java and creates the generic class to allow you to compare any type of data structure. Three different test cases were used using both integers and strings. The first is an ascending list of integers, the second is a descending list of integers, and the third is an unordered list of strings. The output can be seen in the attached image below.

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Order: " + checkOrder(10, 22, 51, 53));

       System.out.println("Order: " + checkOrder(55, 44, 33, 22));

       System.out.println("Order: " + checkOrder("John", " Gabriel", "Daniela", "Zendaya"));

   }

   public static <E extends Comparable<E>> int checkOrder(E var1, E var2, E var3, E var4) {

       E prevVar = var1;

       if (var2.compareTo(prevVar) > 0) {

           prevVar = var2;

       } else {

           if (var3.compareTo(prevVar) < 0) {

               prevVar = var3;

           } else {

               return 0;

           }

           if (var4.compareTo(prevVar) < 0) {

               return 1;

           }  else {

               return 0;

           }

       }

       if (var3.compareTo(prevVar) > 0) {

           prevVar = var3;

       }

       if (var4.compareTo(prevVar) > 0) {

           return -1;

       }

       return 0;

   }

Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one.Ex: If the input is:5 2 4 6 8 10the output is:10,8,6,4,2,To achieve the above, first read the integers into a vector. Then output the vector in reverse.

Answers

Answer:

The program in C++ is as follows:

#include <iostream>

#include <vector>

using namespace std;

int main(){

   vector<int> intVect;

   int n;

   cin>>n;

int intInp;

for (int i = 0; i < n; i++) {

 cin >> intInp;

 intVect.push_back(intInp); }

for (int i = n-1; i >=0; i--) {  cout << intVect[i] << " "; }

 return 0;

}

Explanation:

This declares the vector

   vector<int> intVect;

This declares n as integer; which represents the number of inputs

   int n;

This gets input for n

   cin>>n;

This declares intInp as integer; it is used to get input to the vector

int intInp;

This iterates from 0 to n-1

for (int i = 0; i < n; i++) {

This gets each input

 cin >> intInp;

This passes the input to the vector

 intVect.push_back(intInp); }

This iterates from n - 1 to 0; i.e. in reverse and printe the vector elements in reverse

for (int i = n-1; i >=0; i--) {  cout << intVect[i] << " "; }

Suppose that you write a subclass of Insect named Ant. You add a new method named doSomething to the Ant class. You write a client class that instantiates an Ant object and invokes the doSomething method. Which of the following Ant declarations willnot permit this? (2 points)I. Insect a = new Ant ();II. Ant a = new Ant ();III. Ant a = new Insect ();1) I only2) II only3) III only4) I and II only5) I and III only

Answers

Answer:

5) I and III only

Explanation:

From the declarations listed both declarations I and III will not permit calling the doSomething() method. This is because in declaration I you are creating a superclass variable but initializing the subclass. In declaration III you are doing the opposite, which would work in Java but only if you cast the subclass to the superclass that you are initializing the variable with. Therefore, in these options the only viable one that will work without error will be II.

A common problem in parsing computer languages and compiler implementations is determining if an input string is balanced. That is, a string can be considered balanced if for every opening element ( (, [, <, etc) there is a corresponding closing element ( ), ], >, etc).
Today, we’re interested in writing a method that will determine if a String is balanced. Write a method, isBalanced(String s) that returns true if every opening element is matched by a closing element of exactly the same type. Extra opening elements, or extra closing elements, result in an unbalanced string. For this problem, we are only interested in three sets of characters -- {, (, and [ (and their closing equivalents, }, ), and ]). Other characters, such as <, can be skipped. Extra characters (letters, numbers, other symbols) should all be skipped. Additionally, the ordering of each closing element must match the ordering of each opening element. This is illustrated by examples below.
The following examples illustrate the expected behaviour:
is Balanced ("{{mustache templates use double curly braces}}") should return true
is Balanced("{{but here we have our template wrong!}") should return false
is Balanced("{ ( ( some text ) ) }") should return true
is Balanced("{ ( ( some text ) } )") should return false (note that the ordering of the last two elements is wrong)
Write an implementation that uses one or more Stacks to solve this problem. As a client of the Stack class, you are not concerned with how it works directly, just that it does work.

static boolean isBalanced(String expr)

{

Stack<Character> stack = new Stack<Character>();

for (int i = 0; i < expr.length(); i++)

{

char x = expr.charAt(i);

if (x == '(' || x == '[' || x == '{')

{

// Push the element in the stack

stack.push(x);

continue;

}

if (stack.isEmpty())

return false;

char check;

switch (x) {

case ')':

check = stack.pop();

if (check == '{' || check == '[')

// Check Empty Stack

return (stack.isEmpty());

Scanner scan = new Scanner(System.in);

System.out.println("\nEnter the expression to check is balanced or not !");

The following code is written in Java and modified to do as requested. It asks the user to enter a number that is saved to the amountToChange and then uses the % operator to calculate the number of 5 dollar bills and the number of 1 dollar bills to give back. A test case has been provided and the output can be seen in the attached image below.

       numOnes = amountToChange % 5;

       System.out.print("numFives: ");

Answers

Answer:

False

Explanation:

The Carrier-sense multiple access with collision detection (CSMA/CD) technology was used in pioneer Ethernet to allow for local area networking.  Carrier-sensing aids transmission while the collision detection feature recognizes interfering transmissions from other stations and signals a jam. This means that transmission of the frame must temporarily stop until the interfering signal is abated.

The advent of Ethernet Switches resulted in a displacement of the CSMA/CD functionality.
