The word “computer” has become associated with anything related to screens and keyboard. However, these are not the only parts that makes the computer function. The Central processing unit is often referred to as the brain of the computer which practically coordinates all the activities in the computer. Briefly describe the operation of the Central Processing Unit with emphasis on its sub components.

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;}

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

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.

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.
