3 0

Answer: In discipline such as computer science, a sequence or a list is referred to as an abstract data type which tends to represent a countable no. of the ordered values, under which the same value or content may tend to occur or pops up more than once. Instance of any list is referred to as a computer representation or display of mathematical concept or notion of finite sequence or order.

The abstract data type needs to declare signature of an operations essential for any particular or specific data type. It does not tend to have an implementation.

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>

Victoria is creating a brochure for her photography studio. She designed the layout and placed a photo in the center of the page

cestrela7 [59]

Assuming Victoria is using Adobe Photoshop to create her brochure, below are the steps she is required to follow.

She should first open the image on Photoshop, click on the image option and select duplicate just in case the resized image is not what she wants.

Still on the image option, she should select Image size. A screen will pop up at this point, indicating the image’s current size. For the purposes of image resizing, Victoria should select Pixel dimensions category.

She should be able to type her preferred dimensions for both the width and height. She should make sure ‘Constrain Proportions’ is unchecked to be able to type in separate values.

If she decides to use the photo editing program, she can simply click on the image, and if resize handles appear around it, she can click and drag those to the desired size.

Discuss the differences between a quantitative and qualitative risk analysis. Please write two paragraphs.

Burka [1]

Answer:We start each project to get some business benefits. We design it to achieve users and other stakeholder’s satisfaction. And we build it to improve organization KPIs. But, we live in a world where the project faces many uncertainties. These uncertainties or risks can prevent from achieving our project goals or objectives. So, it is critical that we identify them in time to take care of their effective responses.

The more we know our risks, the more we can evaluate and prioritize them timely for:

Reducing their probable negative impacts, or

Increase their likely positive impacts

We can use Qualitative Risk Analysis and Quantitative Risk Analysis techniques to evaluate and prioritize risks. I see there are a lot of confusions around how these two techniques are different from each other. In this blog, I will address these confusions and differences between these two techniques.

Before we get into the difference between qualitative and quantitative risk analysis/assessment, it is mandatory to understand how we perform risk analysis in projects. Below is the summarized demonstration of the risk analysis:
