Complete Question:

Write statements that output variable numComputers as follows. End with a newline. There are 10 computers.

#include <iostream>

using namespace std;

int main()

{

int numComputers;

cin >> numComputers; // Program will be tested with values: 10.

...

return 0;

}

Answer:

cout << "There are ";

cout << numComputers;

cout << " computers." << "\n";

Explanation:

Using three cout statements the string "There are 10 computers." is printed out, notice that the variable numComputers is entered by the user when the program is run. Another way of concatenating an integer variable and string for printout is by the use of the + (plus) operator.

What is the basic similarities and difference between the three project life cycles model?

MAVERICK [17]

Answer:

Project life cycle is the time taken to complete a project, from start to finish.

The three project life cycles model include the following:

Predictive
Iterative and Incremental
Adaptive

Explanation:

Predictive project life cycles model: In this stage, the three major constraints of the project which are the scope, time and cost are analyzed ahead of time and this analysis is well detailed and the detailed scope of the project is done right from the start of the project.

Iterative and Incremental life cycles model: In this iterative and incremental model, the project is again split into stages that can be sequential or overlapping and at the first iteration of the project, the scope is determined ahead of time.

Adaptive life cycles model: Also in this stage, the project is split up into phases but because these phases are more rapid and ever changing unlike the other models, the processes within the scope can work in parallel.

Similarities

They make use of high level planning.

They are sequential and overlapping.

They make use of high level scope.

Differences

The predictive life cycle model makes use of a detailed scope at the beginning of a project while the other models make use of detailed scope only for each phase.
In predictive life cycle model, the product is well understood, in other models, the projects are complex and not easily understood.
There is periodic customer involvement in predictive and interative life cycle model while the customer involvement in the adaptive model, the customer model is continuous.

Alex

It is a true statement that changing the line spacing will make the document have more white space.

<h3>What is a line spacing in word document?</h3>

This refers to the distance between upper and lower lines of text.

These line spacing are tools that make text much more readable because its places distance between the word lines.

By using a line spacing, there will be more spaces and white spaces on the word document.

Therefore, the statement is a correct statement.
