A chain of dry-cleaning outlets wants to improve its operations by using data from

Write code which takes a sentence as an input from the user and then prints the length of the first word in that sentence.

Afina-wow [57]

import java.util.Scanner;

public class U2_L3_Activity_Four {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.println("Enter a sentence.");

String sent = scan.nextLine();

int count = 0;

for (int i = 0; i < sent.length(); i++){

char c = sent.charAt(i);

if (c != ' '){

count++;

}

else{

break;

}

System.out.println("The first word is " + count +" letters long");

}

We check to see when the first space occurs in our string and we add one to our count variable for every letter before that. I hope this helps!

While creating an animation, Gina has prepared a document stating the purpose and type of audience for the animation. What has

nekit [7.7K]

Answer:

Flash document

Explanation:

While creating an animation, we need to find out the purpose and the type of the audience, the file size and various other features of the animation. And all these details are being mentioned in one document, and we know that as the flash document. The purpose and the target audience both are being mentioned in the flash document. And this flash document is being used as a reference while developing an animation. The purpose and target audience are important factors while designing an animation.

Select the correct navigational path to freeze the top row of your worksheet. Select the panes you wish to freeze. Click the tab

Artemon [7]

Yeah, Your steps ar correct. Let's analyse those steps more easily by the following steps:

$\Large{ \boxed{ \bf{ \color{aqua}{Freeze \: panes:}}}}$

Freeze panes is a feature in spreadsheet applications, such as Microsoft Excel, LibreOffice Calc, and Google Sheets. It "freezes" a row or column, so that it is always displayed, even as you navigate the spreadsheet.

❍ Freezing panes is especially useful if your spreadsheet has a header row, that you want to always be visible.

Select the row below the row(s) you want to freeze. In our example, we want to freeze rows 1 and 2, so we'll select row.
Click the View tab on the Ribbon.
Select the Freeze Panes command, then choose Freeze
Panes from the drop-down menu. ...
The rows will be frozen in place, as indicated by the gray line.

Compare the elements of the basic Software Development Life Cycle with 2 other models. How are they similar? How are they differ

Artemon [7]

Answer:

Explanation:

One of the basic notions of the software development process is SDLC models which stands for Software Development Life Cycle models. SDLC – is a continuous process, which starts from the moment, when it’s made a decision to launch the project, and it ends at the moment of its full remove from the exploitation. There is no one single SDLC model. They are divided into main groups, each with its features and weaknesses. The most used, popular and important SDLC models are given below:

1. Waterfall model

2. Iterative model

3. Spiral model

4. V-shaped model

5. Agile model

Stage 1. Planning and requirement analysis

Each software development life cycle model starts with the analysis, in which the stakeholders of the process discuss the requirements for the final product.

Stage 2. Designing project architecture

At the second phase of the software development life cycle, the developers are actually designing the architecture. All the different technical questions that may appear on this stage are discussed by all the stakeholders, including the customer.

Stage 3. Development and programming

After the requirements approved, the process goes to the next stage – actual development. Programmers start here with the source code writing while keeping in mind previously defined requirements. The programming by itself assumes four stages

• Algorithm development

• Source code writing

• Compilation

• Testing and debugging

Stage 4. Testing

The testing phase includes the debugging process. All the code flaws missed during the development are detected here, documented, and passed back to the developers to fix.

Stage 5. Deployment

When the program is finalized and has no critical issues – it is time to launch it for the end users.

SDLC MODELS

Waterfall – is a cascade SDLC model, in which development process looks like the flow, moving step by step through the phases of analysis, projecting, realization, testing, implementation, and support. This SDLC model includes gradual execution of every stage completely. This process is strictly documented and predefined with features expected to every phase of this software development life cycle model.

ADVANTAGES

Simple to use and understand

DISADVANTAGES

The software is ready only after the last stage is over

ADVANTAGES

Management simplicity thanks to its rigidity: every phase has a defined result and process review

DISADVANTAGES

High risks and uncertainty

Iterative SDLC Model

The Iterative SDLC model does not need the full list of requirements before the project starts. The development process may start with the requirements to the functional part, which can be expanded later.

ADVANTAGES

Some functions can be quickly be developed at the beginning of the development lifecycle

DISADVANTAGES

Iterative model requires more resources than the waterfall model

The paralleled development can be applied Constant management is required

Spiral SDLC Model

Spiral model – is SDLC model, which combines architecture and prototyping by stages. It is a combination of the Iterative and Waterfall SDLC models with the significant accent on the risk analysis.
