Why is continual user involvement a useful way to discover system requirements? Under what conditions might it be used? Under wh

True [87]

Answer:

continual user involvement gives the flexibility to analyze the requirements in right direction. because there is continuous meetings with the end user and he can provide right direction or avoids wrong interpretation of the requirement

Explanation:

continual user involvement is useful when we are following agile methodology where we are building complex systems. it is not useful for simple sytems and following waterfall methodology

Draw a timeline for each of the following scheduling algorithms. (It may be helpful to first compute a start and finish time for

12345 [234]

Answer:

See explanation below

Explanation:

Previos concepts

First Come First Serve (FCFS) "is an operating system scheduling algorithm that automatically executes queued requests and processes in order of their arrival".

Shortest job next (SJN), or the shortest job first (SJF) or shortest "is a scheduling policy that selects for execution the waiting process with the smallest execution time".

Shortest remaining time (SRF) "is a scheduling method that is a preemptive version of shortest job next scheduling'".

Round robin (RR) is an algorithm where the time parts "are assigned to each process in equal portions and in circular order, handling all processes without priority"

Solution for the problem

Assuming the dataset given on the plot attached.

Part a

For this algorithm the result would be:

Job A 0-6

Job B 6-(6+3) = 6-9

Job C 9-(9+1) = 9-10

Job D 10-(10+4) = 10-14

Part b

For this algorithm the result would be:

Job A 0-6

Job C 6-(6+1) = 6-7

Job B 7-(7+3) = 7-10

Job D 10-(10+4) = 10-14

Part c

For this algorithm the result would be:

Job A 0-1 until 14

Job B 2-(2+3) = 2-5

Job C 3-(3+2) = 3-5

Job D 9-(9+5) = 9-14

Part d

For this algorithm the result would be:

Job A 0-2 , 7-9, 12-14

Job B 2-4, 9-10

Job C 4-(4+1) = 4-5

Job D 5-7, 10-12

Write a Python function to determine the volume of material remaining after the hole is drilled. The function should take as inp

Andru [333]

Answer:

height = int(input ("Enter height : ") )

print (height)

width = int( input("Enter length : ") )

print (width)

half_width =width/2

half_height=height/2

while 0==0:

radius = float( input("Enter radius : ") )

print (radius)

if radius<half_width and radius <half_height:

break

def remainingVolume(height,width,radius):

vol_box=height*width*width

print (vol_box)

vol_hole=3.14178*radius*radius*height

print (vol_hole)

remaining_vol=vol_box-vol_hole

print ("Remaining volume is ",remaining_vol)

remainingVolume(height,width,radius);

Explanation:

Take input from user for height ,width and radius. To find volume of box formula is $vol=height* width*length\\$

Let's assume width and length is same so

length= width

Using this formula of box volume find box volume.Now find volume of hole.

Consider hole as small cylinder, find volume of cylinder and subtract from volume of box to get remaining volume of box after hole.

$vol_of_cyl=\pi radius^{2} height$

You are given a file consisting of students’ names in the following form: lastName, firstName middleName. (Note that some studen

pishuonlain [190]

Answer:

#include <iostream> // header file for input output functions

#include <string> // header file for string manipulation

#include <fstream> // for handling file functions

using namespace std; //namespace is used to identify objects like cout, cin

void NamesFunction() {

// Function to convert names to format firstName middleName lastName string Name; //String type variable to store full name

ifstream DataFile; //used to read input from a file

ofstream OutputFile; // used for writing in a file

string lastName; // string type variable to store last name

string firstName; // string type variable to store first name

int position; // used to store position of a specified character in the string

int size; // stores length of full name

DataFile.open("inputtexthere.txt");

//opens text file using object DataFile

OutputFile.open("outputext.txt" );

//opens the text file using object OutputFile

do { //start of Do while loop

getline(DataFile, Name); //reads full names from input stream

position = Name.find(","); // stores position of the , in the name

lastName = Name.substr(0, position);

// stores substring last name from full name

size= Name.length(); //store the length of the entire name

firstName = Name.substr(position + 2, size);

/* stores first name substring from entire name string with the help of specified position */

OutputFile<< firstName << " "; //output first name in text file

cout << firstName << " ";

OutputFile<< lastName << endl; //outputs last name in text file

cout << lastName << endl; }

while (DataFile.eof() == false);

//loop continues until the end of input file is reached

DataFile.close(); //closes input file

OutputFile.close(); } //closes output file

int main(int argc, char *argv[]) //start of main function

{ NamesFunction(); // calls NamesFunction()

}

Explanation:

The brief description of included header files is mentioned in the comments added to the program. Lets begin from the NamesFunction() function.

The string variable Name contains the entire string of full names. Then ifstream class is used which is used to read the input file using an object. The object here is DataFile. ofstream is used to write on a file using an object which is named as OutputFile here. firstName and lastName holds first and last names. position variable stores the specified position. Here the position stores the index position of comma (,) in the string which comes between the lastName and firstName in the input file. size variable holds the length of the Name string.

The function substr is used here to divide the string into substring which is the part of the string that starts at character position and traverses through the specified length of characters.

Here to get the last name in the Name string, substr is used which has two parameters 0 and position means that the substring is obtained starting from 0 position of string and ends where it encounters (,).

Similarly to get the first name, this function is used and it has two parameters; position+2 and size which states that substring will start from two places after (,) and ends till the length of the string. Here position+2 means that it will skip the space between the first name and last name.

Next the names are displayed and stored in the output file via the OutputFile object in the format : firstName middleName lastName

close function will close both the input and output files

Main function calls this function NamesFunction to execute.
