yawa3891 [41]

Answer:

The following program are written in JAVA Programming Language.

//inherit the Calculator class

public class CalculatorWithMemory extends Calculator {  

   private double memory = 0.0;    //initialize double type variable

   public void save() {   //define function

       memory = accumulator;    

   }

   public void recall() {   //define function

       accumulator = memory;

   }

   public void clearMemory() {   //define function

       memory = 0;     //initialize the value

   }

   public double getMemory() {  

       return memory;    // return the value in "memory" variable

   }

}

Explanation:

Here, we inherit the property of the "Calculator" class.

Then, we define the private double type variable "memory" and assign value 0.0.

Then we set the function "save()" inside it we assign the value of "memory" in "accumulator" and close the function.

Then, we define the function "recall()" inside it we assign the value of "accumulator" in "memory" and close the function.

Then we set the function "clearMemory()" inside it we assign "memory" to 0.

After all, we set the double type function "getMemory()" inside we return the value of the "memory".

When breaking a problem down, you often encounter elements that you want to use repeatedly in your code. Sometimes it's appropri
ddd [48]

<u>Answer:</u>

<em>FUNCTION:</em>

  • A function does not require the number of times that the <em>code script needs to be executed </em>
  • When we go for large programming, ie. while creating projects, we can invoke function from one file to another based on the access <em>specifier mentioned for the function. </em>
  • There is a stack call created in the memory whenever a <em>function is called. </em>

<em>LOOP :</em>

  • Whereas the number of times that the loop has to be <em>executed must be defined </em>
  • A loop cannot be called, it can be used only the code block in <em>which it is present. </em>
  • There is not overhead of creating a stack since it is not invoked and there is no <em>transfer of control from one module to another </em>

What programming language supports relational databases?
WINSTONCH [101]

A programming language that supports relational databases is SQL (Structured Query Language)

Structured Query Language (SQL), is the principal method for communicating with Relational Databases.

A relational database is a group of data elements that are linked together by predefined connections. These elements are laid up in the form of a series of tables containing columns and rows.

  • Tables are utilized for storing data about the items that will be displayed in the database.
  • A column in a database contains a specific type of data, whereas a field records the actual value of an attribute.
  • The table's rows indicate a collection of linked values for a single item or entity.

Each entry in a database can be assigned a unique identity known as a primary key, and rows from other tables can be linked together via foreign keys. This data may be accessible in a variety of ways without having to reorganize the database tables itself.

Properly scanning the computer and deleting any viruse. this is Answer

Some of the feedback I hear from new developers working on a programming problem revolves around uncertainty of where to start. You understand the problem, the logic, basics of the syntax, etc. If you see someone else’s code or have someone to guide you, you can follow along. But maybe you feel uncertain about doing it yourself and have trouble turning your thoughts into code at first even though you understand the syntax or logic. Here’s my process and some tips to tackling a sample problem that hopefully some of you may find helpful in your journey.
