Answer:

The algorithm for switching off the electric water heater automatically when the temperature rises to 70 o Celsius is given below.

Explanation:

Let use python code for this question.

we will use if statement to check the condition if the temperature is greater than 70.

When the temperature is 70, then the algorithm will send signal to hardware to turn yourself off.

if(temperature==70):

print("send_turn_off_signal")

Illustrate that the system is in a safe state by demonstrating an order in which the threads may complete.If a request from thre

Kamila [148]

Answer:

a. safe sequence is T2 , T3, T0, T1, T4.

b. As request(T4) = Available, so the request can be granted immediately

c. As request(T2) < Available, so the request can be granted immediately

d. As request(T3) < Available, so the request can be granted immediately.

Explanation:

It will require matrix

[i, j] = Max [i, j] – Allocation [i, j]

A B C D

T0 3 3 3 2

T1 2 1 3 0

T2 0 1 2 0

T3 2 2 2 2

T4 3 4 5 4

Available = (2 2 2 4)

1. Need(T2) < Available so, T2 can take all resources

Available = (2 2 2 4) + (2 4 1 3) (Allocation of T2) = (4 6 3 7)

2. Need(T3)<Available so, T3 will go next

Available = (4 6 3 7) + (4 1 1 0) = (8 7 4 7)

Like wise next T0, T1, T4 will get resources.

So safe sequence is T2 , T3, T0, T1, T4.

(Note, there may be more than one safe sequence).

Solution b.

Request from T4 is (2 2 2 4) and Available is (2 2 2 4)

As request(T4) = Available, so the request can be granted immediately.

Solution c.

Request from T2 is (0 1 1 0) and Available is (2 2 2 4)

As request(T2) < Available, so the request can be granted immediately.

Solution d.

Request from T3 is (2 2 1 2) and Available is (2 2 2 4)

As request(T3) < Available, so the request can be granted immediately.

Write a program that reads a list of integers, and outputs the two smallest integers in the list, in ascending order. The input

kompoz [17]

Answer:

Following are the program in the C++ programming Language.

//header files

#include <iostream>

#include <vector>

using namespace std;//name space

// define main method

int main()

{

//set integer variables

int size, num;

//get input the size of the list

cout<<"Enter size of list: ";

cin >> size;

//set integer type vector variable

vector<int> vecs;

//Set the for loop

for (int index = 0; index < size; ++index)

{//get elements of the list from the user

cout<<" :";

cin >> num;

//push back the elements of the list

vecs.push_back(num);

}

//storing the first two elements in variable

int n = vecs[0], n1 = vecs[1], current , temp;

//set if conditional statement

if (n > n1)

{

//perform swapping

temp = n;

n = n1;

n1 = temp;

}

//Set for loop

for (int index = 2; index < size; ++index)

{

//store the value of the vector in the variable

current = vecs[index];

//set if conditional statement

if (current < n)

{

//interchange the elements of the variable

n1 = n;

n = current;

}

else if(current < n1)

{

n1 = current;

}

//print the value of first two smallest number.

cout <<"\n" <<n << " " << n1 << endl;

return 0;

}

<u>Output:</u>

Enter size of list: 5

:10

:21

2 3

Explanation:

Here, we define the required header files and namespace then, we define "main()" function inside the main function.

Set two integer data type variable "size", "num".
Print message and get input from the user in variable "size".
Then, we set integer vector type variable "vecs".
Set the for loop to get the number of input in the variable "num" from user.
Then, we push back the elements of the list and store first two elements of the list in the variable "n", "n1".
Set the conditional statement to perform swapping.

Define the for loop to store the list of the vector in the integer type variable "current".
Finally, we print the value of the two smallest numbers of the list.

What are Loop Errors? Describe briefly. What aresymptoms of Loop Errors?

victus00 [196]

Answer:

The errors in the loop condition such that it is not giving desired results or it is not running accordingly.There are different types of loop errors which are as following:-

1.Infinite loop:-When the is not able to stop then the error is called infinite loop. for ex:-

int i=1;

while(i!=0)

{

cout<<"I am King"<<endl;

i++;

}

2.Off by one error:-This error mostly happens in loop for arrays as indexing of the array is from 0 to size-1 .So looping over the array up to the size is a off by one error.

3.Equality v/s assignment operator error:-In this error the condition in the loop is like this d=f which is wrong since = is assignment operator it assigns the value of f to d while d==f checks that the value of d and f are equal or not.

4.&& v/s || loop error:- In this error we use and operator (&&) instead of or operator (||) and vice versa.

symptoms of loop errors are not the desired output.
