Assume you are given a boolean variable named isNegative and a 2-dimensional array of ints that has been created and assigned to

Anon25 [30]

Answer:

#include <iostream>

using namespace std;

int main(){

int rows, cols;

bool isNegatives;

cout<<"Rows: ";

cin>>rows;

cout<<"Columns: ";

cin>>cols;

int a2d[rows][cols];

for(int i =0;i<rows;i++){

for(int j =0;j<cols;j++){

cin>>a2d[i][j];} }

int negatives, others = 0;

for(int i =0;i<rows;i++){

for(int j =0;j<cols;j++){

if(a2d[i][j]<0){

negatives++;}

else{

others++;}} }

if(negatives>others){

isNegatives = true;}

else{

isNegatives = false;}

cout<<isNegatives;

return 0;

}

Explanation:

For clarity and better understanding of the question, I answered the question from the scratch.

This line declares number of rows and columns

int rows, cols;

This line declares the Boolean variable

bool isNegatives;

This line prompts user for rows

cout<<"Rows: ";

This line gets the number of rows

cin>>rows;

This line prompts user for columns

cout<<"Columns: ";

This line gets the number of columns

cin>>cols;

This line declares the array

int a2d[rows][cols];

This line gets user input for the array

for(int i =0;i<rows;i++){

for(int j =0;j<cols;j++){

cin>>a2d[i][j];} }

This line declares and initializes number of negative and others to 0

int negatives, others = 0;

The following iteration counts the number of negatives and also count the number of non negative (i.e. others)

for(int i =0;i<rows;i++){

for(int j =0;j<cols;j++){

if(a2d[i][j]<0){

negatives++;}

else{

others++;}} }

This checks of number of negatives is greater than others

if(negatives>others){

If yes, it assigns true to isNegatives

isNegatives = true;}

else{

If otherwise, it assigns false to isNegatives

isNegatives = false;}

This prints the value of isNegatives

cout<<isNegatives;

What are the three main purposes of an operating system? Explain how the old mainframe computers were different from the compute

lbvjy [14]

Answer:(1) To manage the computer's resources, which includes central processing unit, memory, disk drives, and printers, (2) To establish a user interface

(3)To execute and provide services for applications software.

The old mainframe computers have

(1) low memory sizes

(2) slower connectivity speed

(3) Larger sizer

(4) low sophistication.

Explanation: Operating system is a system software that manages the computer resources,helps to establish user interface and it helps to provide services for application softwares.

Operating system software includes WINDOWS X,WINDOWS 7,WINDOWS 8,LINUX,etc.

Mainframe computers are computers used by large multinational companies for processing bulk data. Old mainframe computers were produced by IBM(INTERNATIONAL BUSINESS MACHINE) in the year 1952 they are classed two scientific and commercial mainframe computers with different information although they had some incompatibilities. Old mainframe computers are large in size with low processing speed, sophistication and storage compared to present day system.

Write a program that reads an integer, a list of words, and a character. The integer signifies how many words are in the list. T

hammer [34]

Answer:

In C++:

#include<iostream>

#include<vector>

using namespace std;

int main() {

int len;

cout<<"Length: "; cin>>len;

string inpt;

vector<string> vect;

for(int i =0;i<len;i++){

cin>>inpt;

vect.push_back(inpt); }

char ch;

cout<<"Input char: "; cin>>ch;

for(int i =0;i<len;i++){

size_t found = vect.at(i).find(ch);

if (found != string::npos){

cout<<vect.at(i)<<" ";

i++;

}

return 0;

}

Explanation:

This declares the length of vector as integer

int len;

This prompts the user for length

cout<<"Length: "; cin>>len;

This declares input as string

string inpt;

This declares string vector

vector<string> vect;

The following iteration gets input into the vector

for(int i =0;i<len;i++){

cin>>inpt;

vect.push_back(inpt); }

This declares ch as character

char ch;

This prompts the user for character

cout<<"Input char: "; cin>>ch;

The following iterates through the vector

for(int i =0;i<len;i++){

This checks if vector element contains the character

size_t found = vect.at(i).find(ch);

If found:

if (found != string::npos){

Print out the vector element

cout<<vect.at(i)<<" ";

And move to the next vector element

i++;

}
