Answer:
name is a reserved word in JS and cannot be used as an identifier
Explanation:
From the group of answer choices provided the only one that may be a problem would be using the word name as a parameter. Although name is not a reserved word per say in JS it is in HTML, and since JS targets HTML it could cause some errors. This however does not prevent this code from running correctly. JS does not require semicolons anymore, and the opening and closing braces for a body of code does not need to be on their own lines. Also, variable names are not Strings and do not need to be inside quotes, even for console.log()
Programming languages categorize data into different types. Identify the characteristics that match each of the following data types.

c. Is limited to whole numbers (counting numbers 1, 2, 3, ...)
Answer:
a) Integer data type.
b) Real data type.
c) Boolean data type.
Explanation:
a) Integer data type is limited to whole numbers (counting numbers 1, 2, 3…….).
b) Real data type can store fractions and numbers with decimal positions (such as dollar values like $10.95).
c) Boolean data type is limited to values that are either true or false (represented internally as 1 and 0 respectively).
Which of the given assertion methods will return true for the code given below? Student student1 = new Student(); Student student2 = new Student(); Student student3 = student1;
The Student class is as follows.
public class Student{
private String name;
}
a. assertEquals(student1, student2);
b. assertEquals(student1, student3);
c. assertSame(student 1, student3);
d. assertSame(student1, student2);
Answer:
The true statements are :
A. assertEquals(student1,student2)
C. assertSame(student1,student3)
Explanation:
AssertEquals() asserts that the objects are equal, but assertSame() asserts that the passed two objects refer to the same object or not, if found same they return true, else return false.
Methods are collections of named code segments that are executed when evoked
The assertion method that will return true for the given code is: assertEquals(student1,student2)
The code segment is given as:
Student student1 = new Student();
Student student2 = new Student();
Student student3 = student1;
In Java, the assertEquals() method returns true if two objects have equal values.
Assume student1 and student2 have equal values, the statement assertEquals(student1,student2) will return true

write a programmimg code in c++ for school based grading system, the program should accept the subject in the number of students from a user and store their details in the array of type student(class) the student class you have:
1. number student name, index number remarks as variables of type string, marks as integer and grade as char.
2. avoid function called getData which is used to get student details
3. avoid function called calculate which will work on the marks and give the corresponding great and remarks as given below on
Marks 70-100 grade A remarks excellent Mark 60-69 Grade B remarks very good marks 50-59 grade C remarks pass maths 0-49 grade F remarks fail
Answer:
The program is as follows:
#include <iostream>
#include <string>
using namespace std;
class Student{
string studName, indexNo, remarks; int marks; char grade;
public:
void getData(){
cin.ignore();
cout<<"ID: "; getline(cin,indexNo);
cout<<"Name:"; getline(cin,studName);
cout<<"Marks: ";cin>>marks; }
void calculate(){
if(marks>=70 && marks<=100){
remarks ="Excellent"; grade = 'A'; }
else if(marks>=60 && marks<=69){
remarks ="Very Good"; grade = 'B'; }
else if(marks>=50 && marks<=59){
remarks ="Pass"; grade = 'D'; }
else{
remarks ="Fail"; grade = 'F'; }
cout << "Grade : " << grade << endl;
cout << "Remark : " << remarks << endl; }
};
int main(){
int numStudents;
cout<<"Number of students: "; cin>>numStudents;
Student students[numStudents];
for( int i=0; i<numStudents; i++ ) {
cout << "Student " << i + 1 << endl;
students[i].getData();
students[i].calculate(); }
return 0;}
Explanation:
This defines the student class
class Student{
This declares all variables
string studName, indexNo, remarks; int marks; char grade;
This declares function getData()
public:
void getData(){
cin.ignore();
Prompt and get input for indexNo
cout<<"ID: "; getline(cin,indexNo);
Prompt and get input for studName
cout<<"Name:"; getline(cin,studName);
Prompt and get input for marks
cout<<"Marks: ";cin>>marks; }
This declares funcion calculate()
void calculate(){
The following if conditions determine the remark and grade, respectively
if(marks>=70 && marks<=100){
remarks ="Excellent"; grade = 'A'; }
else if(marks>=60 && marks<=69){
remarks ="Very Good"; grade = 'B'; }
else if(marks>=50 && marks<=59){
remarks ="Pass"; grade = 'D'; }
else{
remarks ="Fail"; grade = 'F'; }
This prints the grade
cout << "Grade : " << grade << endl;
This prints the remark
cout << "Remark : " << remarks << endl; }
};
The main begins here
int main(){
This declares number of students as integer
int numStudents;
Prompt and get input for number of students
cout<<"Number of students: "; cin>>numStudents;
This calls the student object to declare array students
Student students[numStudents];
This is repeated for all students
for( int i=0; i<numStudents; i++ ) {
Print number
cout << "Student " << i + 1 << endl;
Call function to get data
students[i].getData();
Call function to calculate
students[i].calculate(); }
return 0;}

Hint: The function isNaN() returns true if the parameter is not a number.
Answer and Explanation:
function processNumbers(alist){
var Ourarray= new array(alist);
Ourarray.foreach(
if(isNaN()){
Console.log( "An element in the list is not a number."};
break;
}
}
processNumbers(alist)
From the above, we have defined a function that takes an array parameter(the following array variable will make sure of that). We test each element in the array using foreach array function. The for each function runs the if statement and if isNan is true for each of the elements in the array.
a. Download the attached �Greetings.java� file.
b. Implement the �getGreetings� method, so that the code prompts the user to enter the first name, the last name, and year of birth, then it returns a greetings message in proper format (see the example below). The �main� method will then print it out. Here is an example dialogue with the user:
Please enter your first name: tom
Please enter your last name: cruise
Please enter your year of birth: 1962
Greetings, T. Cruise! You are about 50 years old.
Note that the greetings message need to be in the exact format as shown above (for example, use the initial of the first name and the first letter of the last name with capitalization).
c. Submit the final �Greetings.java� file (DO NOT change the file name) online.
Answer:
Code:
import java.util.*;
public class Greetings
{
public static void main(String[] args)
{
Scanner s = new Scanner(System.in);
System.out.println(getGreetings(s));
}
private static String getGreetings(Scanner console)
{
System.out.print("Please enter your first name: ");
String firstName=console.next();
char firstChar=firstName.toUpperCase().charAt(0);
System.out.print("Please enter your last name: ");
String lastName=console.next();
lastName=lastName.toUpperCase().charAt(0)+lastName.substring(1, lastName.length());
System.out.print("Please enter your year of birth: ");
int year=console.nextInt();
int age=getCurrentYear()-year;
return "Greetings, "+firstChar+". "+lastName+"! You are about "+age+" years old.";
}
private static int getCurrentYear()
{
return Calendar.getInstance().get(Calendar.YEAR);
}
}

The Curiosity Rover has recently landed on Mars and likes to send Twitter updates on its progress. If a tweet is posted 10 minutes after it was sent, how far is Curiosity from Earth? (Assume there is no network lag.)
Answer:
1.8 * 10^11 m
Explanation:
Given that :
Time taken for tweet to me posted after been sent, t = 10 minutes
t in seconds :
60 seconds = 1 minute
10 minutes = (10 * 60) = 600 seconds
Tweet sent will br transmitted at the speed of light, c = 3 * 10^8 m/s
Recall :
Speed = distance / time
Distance = speed * time
Distance of Curiosity from Earth = (3 * 10^8 * 600)
Distance of curiosity from earth = 1.8 * 10^11 m

cpp Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Ex: If the input is:
Answer:
#include <iostream>
int main() {
// The length of the list
int l;
// The array containing the numbers
int *list;
// Threshold, last value in array
int thresh;
// Read in first value and create an array with the size of that value
scanf("%d", &l);
list = (int*) malloc(l * sizeof(int));
for(int i = 0; i < l; i++) {
scanf("%d", &list[i]);
}
thresh = list[l - 1];
// Print the values
for(int i = 0; i < l - 1; i++) {
if (list[i] <= thresh) {
printf("%d ", list[i]);
}
}
printf("\n");
free(list);
}
Explanation:
The program assumes at least two values are provided. The length of the list and the threshold.
We first read in an integer, and find out how many more integers we need to read. We create an array with the appropriate size, and loop through to fill the array with values. We know the last value is the threshold, and so we do one more loop to compare the values in the array with the threshold.
