g Add a throw statement to the processNumbers function that throws the message "An element in the list is not a number." if one of the elements in toProcess is not a number. Hint: The function isNaN() returns true if the parameter is not a number.
Answers
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.

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
Answers
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;}

Answers
Answer:
r = 1
Explanation:
Average processing time ( p ) = 3 minutes
Average inter-arrival time ( a ) = 3 minutes
number of servers ( m ) = 3
Determine the value of r
r ( offered load ) = p/a
= 3 / 3 = 1
∴ value of r ( offered load ) = 1
