Answer:

True.

Explanation:

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are seven (7) main stages in the creation of a software and these are;

1. Planning.

2. Analysis.

3. Design.

4. Development (coding).

5. Testing.

6. Implementation and execution.

7. Maintenance.

One of the most important steps in the software development life cycle (SDLC) is design. It is the third step of SDLC and comes immediately after the analysis stage.

Basically, the design phase is the stage where the software developer describes the features, architecture and functions of the proposed solution in accordance with a standard.

Hence, in an event-driven program, the software developer design the screens, define the objects to be used, and define how the screens will connect to other sources or resources.

Answer:

"void" is the correct answer for the given question.

Explanation:

In the function body the value of balance variable is not return that means we use void return type .The void return type is used when the function does not return any value .

If the function are int return type that means it return "integer value ".

if the function are double return type that means it return the "double value" .

The complete implementation of this method is

public void deposit(double amount) // function definition

{

balance = balance + amount; // statement

}

For each of the following application areas state whether or not the tree data structure appears to be a good fit for use as a s

Cerrena [4.2K]

Answer:

a) Chess game moves:- Tree data structure is not a good fit.

b) Public transportation paths:- Tree data structure is not a good fit.

c) Relationshi[p among computer files and folders:- Tree data structure is a good fit.

d) Genealogical information:- Tree data structure is a good fit.

e) Parts of books:- Tree data structure is a good fit.

f) Programming language history:- Tree data structure is not a good fit.

g) Mathematical expression:- Tree data structure is a good fit.

Explanation:

a) Chess game moves:- Tree data structure is not a good fit. Since in tree data structure moving backward or sharing the node is not that much easy. Presume, In chess, you have to check any box is empty or not. Here, Graph is the best fit.

b) Public transportation paths:- Tree data structure is not a good fit. whenever shortest path, routes, broadcast come always graph is a good option. Because in the tree you don't know how many time you visit that node

c) Relationshi[p among computer files and folders:- Tree data structure is a good fit. Since they have a predefined route. Go to 'c' drive. Open a particular folder and open a particular file.

d) Genealogical information:- Tree data structure is a good fit. Since genealogical information also has a predefined route. Here, the Graph is not suitable.

e) Parts of books:- Tree data structure is a good fit. Since manages the chapters and topics are not that much complex. You can see any book index which is in a very pretty format.

f) Programming language history:- Tree data structure is not a good fit. To store the history of the programming language we need some unconditional jumps that's why the tree is not suitable.

g) Mathematical expression:- Tree data structure is a good fit. The tree is suitable in some cases. We have an expression tree for postfix, prefix.
