Write a program that declares a two-dimensional array named myFancyArray of the type double. Initialize the array to the followi
kirill115 [55]

Answer:

This solution is provided in C++

#include <iostream>

using namespace std;

double sumFancyArray(double myarr[][6]){

   double sum = 0.0;

   for(int i = 0;i<2;i++)    {

       for(int j = 0;j<6;j++){

       sum+=myarr[i][j];    

       }}    

   return sum;

}

void printFancyArray(double myarr[][6]){

   for(int i = 0;i<2;i++)    {

       for(int j = 0;j<6;j++){

       cout<<myarr[i][j]<<" ";    

       }

   }

}

int main(){

   double myFancyArray[2][6] = {23, 14.12, 17,85.99, 6.06, 13, 1100, 0, 36.36, 90.09, 3.145, 5.4};

   cout<<sumFancyArray(myFancyArray)<<endl;

   printFancyArray(myFancyArray);

   

   return 0;

}

Explanation:

This function returns the sum of the array elements

double sumFancyArray(double myarr[][6]){

This initializes sum to 0

   double sum = 0.0;

This iterates through the row of the array

   for(int i = 0;i<2;i++)    {

This iterates through the column

       for(int j = 0;j<6;j++){

This adds each element

       sum+=myarr[i][j];    

       }}    

This returns the sum

   return sum;

}

This method prints array elements

void printFancyArray(double myarr[][6]){

This iterates through the row of the array

   for(int i = 0;i<2;i++)    {

This iterates through the column

       for(int j = 0;j<6;j++){

This prints each array element

       cout<<myarr[i][j]<<" ";    

       }

   }

}

The main starts here

int main(){

This declares and initializes the array

   double myFancyArray[2][6] = {23, 14.12, 17,85.99, 6.06, 13, 1100, 0, 36.36, 90.09, 3.145, 5.4};

This calls the function  that returns the sum

 cout<<sumFancyArray(myFancyArray)<<endl;

This calls the function that prints the array elements

   printFancyArray(myFancyArray);

   

   return 0;

}

* 8) Embedded operating systems are specialized software meant only to manage the
Ede4ka [16]

Answer:

True

Explanation:

Embedded operating systems are operating systems which supports hardware which is not a computer and allows the hardware to perform its task.

An example of a device with an embedded operating system is an SD card. The operating system on the card allows the card to be readable by the computer which its is plugged to.

Other examples of hardware with embedded systems are traffic lights, digital televisions, ATMs, point of sale (POS) and digital cameras.

Professor Midas drives an automobile from Newark to Reno along Interstate 80. His car’s gas tank, when full, holds enough gas
zmey [24]

Answer:

The GREEDY Algorithm

Explanation:

Based on the situation given in question, the Greedy algorithm shall give the optimal solution to professor

Suppose that the cities are at locations0 =x0< x1< . . . < x

We shall use the induction method to prove that G is the optimal solution valid for numbers less than n

We assume another solution Z which we initially consider to be optimum as well, based on that when Z fills the tank, it fills it to full level

Let us state the values in case of n intervals. Given below, we say that g1 is the first stop and z1 is also the first stop.

This can be written as ;

G=g1, g2, . . . , gk

Z=z1, z2, . . . , zk’

Here k’ <= k and k < n

Let I be an idex where for the first time gi is not equal to zi

Considering t= maxi Zi

Z′=g1, z2, z3, . . . , zk′

Now since z2, z3, . . . , zk′ should be an optimal stopping pattern for the problem otherwise we have chosen Z, with smaller gas filling (not feasible)

Using induction hypothesis we conclude thatg2, . . . , gk is an optimal stopping pattern, which is based on greedy algorithm

Vivian wants to increase the storage capacity of her computer. Which components should she upgrade?
Nikitich [7]

Answer:

Hard drive

Explanation:

The hard drive is where the operating system, programs and data reside on (unless the data is saved and backed up elsewhere). An older hard drive that uses platters for reading and writing data to it will be slower than a later model solid state device. Newer hard drives have very fast access speeds compared to older units.
