4 0

Answer:

Explanation:

The function floor() is used to give the integer which is smaller than or equal to the provided decimal value.

for example:

let a=5.8

floor(a);

the function provides the value 5 (smaller than or equal to 5.8).

In the given code:

variable num assigns the number 3.14.

then, floor(3.14) gives the value 3 (smaller than or equal to 3.14).

then, the echo print the value on the screen.

Therefore, the correct answer is 3.

What are the primary benefits of relying on systems development standards?

Sunny_sXe [5.5K]

Answer:

The benefits of relying on System Development Standards is explained below.

Explanation:

There are many benefits of having a Well Defined Systems Development. It helps in having a pre - planned and well defined structure before the project starts. It helps in having a Clear view of the whole project and also each phase of the whole System Development. It helps in having an understanding of cost required and the revenues generated at each phase of the whole system development. It helps in having an understanding of the goal of each phase and procedures need to be followed for that particular goal. It also helps in having the quality checked and the improvements need to be made for the desired quality.

Explanation:

[NB: since it is very long there is the need for me to put it it a document form. Kindly check the doc. Files. The file A is the sort Analysis.Java file and the file B is the sort.Java file].

The concept of algorithm time measurement strictly depends on the following;

=> The measurement of time, space or energy on different sizes.

=> Plotting of the measurements and characterizing them.

=> Running or implementation of the algorithm.

Programming language such as Java can be used in accessing the operating system clock and Java had two static methods.

Explain the concepts o f polymorphism, Encapsulation, Inheritance in detail with suitable examples?

levacccp [35]

Answer:

Encapsulation:-It is the binding of the data and functions so that they works as one unit.

Inheritance:-When one class acquires the property of another class it is called inheritance.

Polymorphism :-It generally means more than one form

Explanation:

Encapsulation:- class is an example of encapsulation it can hold different data types and functions in a single container called class.

class Name{

public:

string first_name;

string last_name;

void Display()

{

cout<<first_name<<" "<<last_name<<endl;

}

};

Inheritance:-The property of a class acquiring the properties of another class is called inheritance.

Now we will inherit the above defined class.

class person: public Name

{

public:

char gender;

int age;

void Display()

{

cout<<first_name<<" "<<last_name<<gender<<age<<endl;

}

};

int main()

{

Name n;

person p;

n.Display();

p.Display();

}

Polymorphism- There are two types of polymorphism:-

1.Run time polymorphism=The values are decided at run time.

2.Compile time polymorphism=The values are decided at compile time.

Example:-In the above example we have function Display() in both the classes.This is an example of compile-time polymorphism. We are deciding at the time of compilation which display to use.

Afina-wow [57]

Answer:

b) uppercase for variable names, and lowercase for constants and functions

Explanation:

Given

Programming language: prolog

Required

The case type for variables, constants and functions

In prolog,

Variable names begin with uppercase

e.g. Name, NAME

While constants and functions begin with lowercase

e.g. name, addnumbers()

<em>Hence, (b) is correct</em>
