Read integers from input and store each integer into a vector until -1 is read. Do not store -1 into the vector. Then, output al
weqwewe [10]

Answer:

The program in C++ is as follows:

#include <iostream>

#include <vector>

using namespace std;

int main(){

vector<int> nums;

int num;

cin>>num;

while(num != -1){

 nums.push_back(num);

 cin>>num; }  

for (auto i = nums.begin(); i != nums.end(); ++i){

    cout << *i <<endl; }

return 0;

}

Explanation:

This declares the vector

vector<int> nums;

This declares an integer variable for each input

int num;

This gets the first input

cin>>num;

This loop is repeated until user enters -1

while(num != -1){

Saves user input into the vector

 nums.push_back(num);

Get another input from the user

 cin>>num; }

The following iteration print the vector elements

<em> for (auto i = nums.begin(); i != nums.end(); ++i){ </em>

<em>     cout << *i <<endl; } </em>

Anna11 [10]

Answer:

A. OU

Explanation:

An organization unit (OU) is used to group objects that are related, having similar administrative and security requirements within a domain. It provides a way of classifying objects in a directory, such as differentiating between objects with the same name or managing and creating objects. An OU can be nested into another OU, thus it can be used to create a hierarchy within an organization.

Which is an example of artificial intelligence in computers? A. multimedia software B. encryption software C. voice recognition
andrezito [222]

Answer:

its option b encryption software

Explanation:

Artificial intelligence (AI) is intelligence demonstrated by machines, unlike the natural intelligence displayed by humans and animals, which involves consciousness and emotionality. The distinction between the former and the latter categories is often revealed by the acronym chosen. 'Strong' AI is usually labelled as AGI (Artificial General Intelligence) while attempts to emulate 'natural' intelligence have been called ABI (Artificial Biological Intelligence). Leading AI textbooks define the field as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of successfully achieving its goals.[3] Colloquially, the term "artificial intelligence" is often used to describe machines (or computers) that mimic "cognitive" functions that humans associate with the human mind, such as "learning" and "problem solving".
