Suppose that the following processes arrive for execution at the times indicated. Each process will run for the amount of time l

isted. In answering the questions, use non-preemptive scheduling, and base all decisions on the information you have at the time the decision must be made.
Process Arrival Time Burst Time
P1 0.0 8
P2 0.4 4
P3 1.0 1
a) What is the average turnaround time for these processes with the FCFS scheduling algorithm?

b) What is the average turnaround time for these processes with the SJF scheduling algorithm?

Answer:

a) 10.53

b) 9.53

Explanation:

a) Average Turnaround Time: ( (8-0)+(12-0.4)+(13-1.0) ) / 3 = 10.53

b) Average Turnaround Time: ( (8-0)+(13-0.4)+(9-1.0) ) / 3 = 9.53

Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:
rosijanka [135]

Answer:

#include <stdlib.h>

#include <time.h>

#include<iostream.h>

int main(void) {

   int seedVal = 0;  

   seedVal = 4;

   srand(seedVal);

  /* Solution*/

  cout<<rand() % 149 + 100<<endl;

  cout<<rand() % 149 + 100<<endl;

  return 0;

}

Explanation:

We start with the required include statements to enable use of srand, rand and time functions. I have also added iostream library to use "cout" function.

After that, the seed is initialized using srand(). And then the two rand functions are called with ranges including and between 100 and 149, and printed out.

You would like the user of a program to enter a customer’s last name. Write a statement thaUse the variables k, d, and s so that
mojhsa [17]

Answer:

1st question:

Use the variables k, d, and s so that they can read three different values from standard input an integer, a float, and a string respectively. On one line, print these variables in reverse order with exactly one space in between each. On a second line, print them in the original order with one space in between them.

Solution:

In Python:

k = input()  #prompts user to input value of k i.e. integer value

d = input()  #prompts user to input value of d i.e. float value

s = input()  #prompts user to input value of s i.e. a string

print (s, d, k)  #displays these variable values in reverse order

print (k, d, s)#displays these variable values in original order

In C++:

#include <iostream>    // to use input output functions

using namespace std;   //to identify objects like cin cout

int main() {    //start of main function

  int k;   //declare int type variable to store an integer value

  float d; //  declare float type variable to store a float value

  string s;   //  declare string type variable to store an integer value

  cin >> k >> d >> s;    //reads the value of k, d and s

  cout << s << " " << d << " " << k << endl;     //displays these variables values in reverse order

  cout << k << " " << d << " " << s << endl;   } // displays these variable values in original order

Explanation:

2nd question:

You would like the user of a program to enter a customer’s last name. Write a statement that asks user "Last Name:" and assigns input to a string variable called last_name.

Solution:

In Python:

last_name = input("Last Name:")

# input function is used to accept input from user and assign the input value to last_name variable

In C++:

string last_name;  //declares a string type variable named last_name

cout<<"Last Name: ";  // prompts user to enter last name by displaying this message Last Name:

cin>>last_name; // reads and assigns the input value to string variable last_name

The programs alongwith their outputs are attached.

A large software development company employs 100 computer programmers. Of them, 45 areproficient in Java, 30 in C, 20 in Python,
melisa1 [442]

Answer:

18, 13, 19

Explanation:

Number of computer programmers proficient only in Java = 45 - ( 1+1+6) = 37

Number of computer programmers proficient only in C++ = 30 - (6+1+5) = 18

Number of computer programmers proficient only in python = 20 - ( 1+1+5) = 13

Number of computer programmers are not proficient in any of these three languages = 100 - ( 37 + 18 + 13 + 1+ 1+ 5+ 6 ) = 100 - 81 = 19
