An Access Control Matrix ACM can be defined as a table that maps the permissions of a set of subjects to act upon a set of objects within a system. The matrix is a two-dimensional table with subjects down the columns and objects across the rows. The permissions of the subject to act upon a particular object are found in the cell that maps the subject to that object.

Summary

The rows correspond to the subject

The columns correspond to the object

What does each cell in the matrix contain? Answer: Each cell is the set of access rights for that subject to that object.

grigory [225]

Answer:

#include <iostream>

using namespace std;

int main()

{

 

  int arr[]={3,-9,9,33,-4,-5, 100,4,-23};

  int pos;

  int n=sizeof(arr)/sizeof(arr[0]);

  for(int i=0;i<n;i++){

      if(arr[i]>=0){

          pos++;

      }

  }

  cout<<"Number of positive integers is "<<pos<<endl;

  return 0;

}

Explanation:

create the main function in the c++ programming and declare the array with the element. Then, store the size of array by using the formula:

int n=sizeof(arr)/sizeof(arr[0]);

after that, take a for loop for traversing the array and then check condition for positive element using if statement,

condition is array element greater than or equal to zero.

if condition true then increment the count by 1.

this process happen until the condition true

and finally print the count.

alina1380 [7]

Answer:

<div>

Explanation:

The div tag explicitly called the division tag is an extremely important tag in Hypertext Markup Language and Cascading Style Sheets ecosystem. Like most of the other tags used during writing and styling web documents, the div tags plays an important role as it serves as a container which is capable of holding several HTML elements such as the head, body , paragraph tags and so on. All elements within the div tags can be easily styled using the same CSS style specification without having to take the more singular and tedious approach. They also aid fast manipulation using compatible languages. Hence, using the cajas attribute, several elements within a div can be styled at the same time. Also note that , line breaks are automatically placed before and after a tag.

Hence, the div tag is the most appropriate answer.

LekaFEV [45]

Answer:

a.the number of cycles per second

Explanation:

The frequency of a sine wave is defined as the number of cycles per second.

Frequency is the inverse of the time period. The frequency of a sine wave is given by 1/TimePeriod . It is generally expressed in units of Hertz(Hz) or sec^-1. Larger the time period, lower will be the frequency and vice versa. So for higher frequency waves we need to ensure that the time period is small.
