How does naming affect a variable’s creation and use?

Computers and Technology
1 answer:
Evgen [1.6K]2 years ago
4 0

Answer:

Each variable is named so it is clear which variable is being used at any time. It is important to use meaningful names for variables: ... The name given to each variable is up to the programmer, but ideally a variable name should have meaning, ie it should reflect the value that it is holding.

Variables make code more than a static set of instructions. They allow logic to occur, enabling developers to measure time, analyze data, and customize the program to the user. Variables are so important to the code that they deserve a good name that accurately describes their purpose

Answer:

C. NFC

Explanation:

NFC stands for Near Field Communication. NFC is been embedded in recent mobile device (ranging from phone to tablet) to ease payment. NFC is a short-range high frequency wireless communication technology that enables the exchange of data between devices over about a 10 cm distance.

From the option, Bluetooth look like a probable answer but when they are both compared; we realized that NFC has a shorter set-up time over bluetooth and is therefore faster than bluetooth.

olga55 [171]

Answer:

Following are the code to the given question:

#include <iostream>//header file

using namespace std;

int main()//main method

{

int r=26,x,y;//defining integer variable  

char c;//defining a character variable

for(x= 1; y<= r; x++)//using for loop for count value

{

for(y= 1; y<= x; y++)//using for loop to convert value in triangle  

{

c=(char)(y+64);//convert value into character  

cout << c;//print character value

}

cout << "\n";//use print method for line break

}

return 0;

}

Output:

Please find the attachment file.

Explanation:

In this code, three integer variable "x,y, and r", and one character variable "c" is declared, that is used in the nested for loop,  in the first for loop it counts the character value and in the next for loop, it converts the value into a triangle and uses the char variable to print its character value.

densk [106]

The decisions that a specialized drone delivering medical supplies make once it's algorithm has started and it is scanning its surround are:

  • A  tilt backyard when sensor detects an obstacle within 10 feet.
  • To disable self flying and alert pilot when sensor detects an obstacle within 3 feet.
  • To resume normal speed when sensor doesn't detect an obstacle within two feet.

<h3>How are drones used in healthcare?</h3>

Hospitals are known to have started  using drones to transport laboratory samples and also to carry out other kinds of humanitarian aids.

The use of  drones  is said to be one that is cost-effective and it is one that bring blood products, vaccines, medical supplies, and others to rural areas or areas that has small infrastructure.

A drone can find way to move around obstacles but they should not shut down where there is obstacle.

How are static variables and methods created in Java? What happens if a non-static method of a class tries to access a static va
9966 [12]

Answer:

Static variables are the variables decaraed with keyword static, static variables must be deacraled inside the class body, means we can not declare a static variable inside a method or consttructor, static variable belongs to class, for a class only one copy is created for static variable and used by all the objects/instances.

Static variable can access with class name like

X.i

Static method are the methods defined with static keyword, static method are also part of a class, we can access static meethod using class name like

X.printI()  

Explanation:

class X

{

//to create a static variable we need use static keyword with variable name like

public static int i;

// to create a static method we need to use static keyword while defining a method like

public static void printHello() {

 System.out.println("Hello");

}

/*

 * A non static method can access static variable of a class there is no issue

 * with that we can use a static variable in a non static method like

 */

public void printI() {

 System.out.println(i);

}

/*

 * As long as the class exist in JVM static variables will be there, as static

 * variable belong to class not with the instance,

 * it does not matters if there are instance exist or not

 */

}
