Answer:

None of them is correct, but it seems one of the option has missing words.

The exact definition is, MySQL is a database management system.

Explanation:

Agile is not a programming language, it is a software development methodology.

HTML stands for "Hypertext Markup Language"

Java and JavaScript are different languages.

Actually,  MySQL is a database management system. It is used to deal with the relational databases. It uses SQL (Structured Query Language).

Jet001 [13]
Melinda and Bill should brainstorm to think of ways on how to have another additional income. In the case of Melinda, she could start a small business or any ways in which she could earn at home.

Given an integer variable strawsOnCamel, write a statement that uses the auto-increment operator to increase the value of that v
Reptile [31]

Answer:

The program to this question can be given as follows:

Program:

#include <stdio.h> //include header file for using basic function

int main() //defining main method

{

int strawsOnCamel=0; //defining integer variable and assign value

for(int i=1;i<=5;i++) //loop for increment integer variable value

{

//code

strawsOnCamel++; //increment value by 1

printf("%d\n", strawsOnCamel); //print value

}

return 0;

}

Output:

1

2

3

4

5

Explanation:

In the C language code above the header file is entered, and a whole variable strawsOnCamel is specified within the main method, which gives a value of 0.

  • Then a for loop is defined inside a loop an integer variable i declared that starts from 1 and ends with 5.
  • Inside a loop, the strawsOnCamel variable is used that increments its value by 1 and prints its value.

A shipping company uses the following function to calculate the cost in dollars of shipping based on the weight of the package (
Gwar [14]

Answer:

I am writing the code in JAVA and C++. Let me know if you want the code in some other programming language. Both the programs works the same but the only difference is that i have used logical operator AND (&&) with C++ code to check each condition.

JAVA code:

import java.util.Scanner;    // to take input from the user

public class ShippingCost {  // ShippingCost class

public static void main(String[] args) {   // main method entry to the program

Scanner input = new Scanner(System.in);  //allows to take input from user

System.out.print("please enter the weight of the package: "); /*prompts the user to enter the weight of package.*/

double weight = input.nextDouble();  /*reads and stores the input values(weight) entered by the user*/

       double cost=0;  //holds the value of cost

 if (weight<=0)  /* checks if the user enters weight value less than or equals to 0 */

 { System.out.println("invalid input."); //prints invalid input

     System.exit(0); //exits the program

 }

    else if (weight > 0 && weight <= 1)  /*if weight is greater than 0 and less than or equal to 1*/

   cost = 3.5;  /*if the above condition is true then it stores the value 3.5 in cost variable */

 else if (weight <= 3)  // if value of weight is less than or equal to 3

   cost = 5.5;  /*if the above condition is true then it stores the value 5.5 in cost variable */

 else if (weight <= 10)  // if value of weight is less than or equal to 10

   cost = 8.5;  /*if the above condition is true then it stores the value 8.5 in cost variable */

 else if (weight <= 20)  // if value of weight is less than or equal to 20

   cost = 10.5;/*if the above condition is true then it stores the value 10.5 in cost variable */

 else  // if the value of weight is greater than 20

 {  System.out.println("The package cannot be shipped");

// displays package cannot be shipped

      System.exit(0);  //exits the program if weight>20}

 System.out.println("The shipping cost is: $" + cost);     /*prints the value stored in the cost from any of the above conditions */

} }

C++ Code

#include <iostream>//to use input output functions

using namespace std;

int main() // start of main() function body

{ double weight; //stores weight value

   double cost= 0; //stores cost value

cout << "please enter the weight of the package:" << endl;

//prompts user to enter the weight

cin >> weight;    

//reads the value of weight entered by the user

  if (weight<=0) //if value of weight entered by user is less than or equal to 0

 { cout<<"invalid input."; //displays invalid input

     exit(0); //exits the program

 }

/*the below else if conditions are checked, if any one of them is true then the cost displayed in the output will be the which is assigned to cost variable of that specific if condition's body which evaluates to true. */

    else if (weight > 0 && weight <= 1)

   cost = 3.5;

 else if (weight > 1 && weight <=3)

   cost = 5.5;

 else if (weight > 3 && weight <= 10)

   cost = 8.5;

 else if (weight> 10 && weight <= 20)

   cost = 10.5;

 else //if weight>20

//displays the message below and exits the program

 {  cout<<"The package can not be shipped";

      exit(0); }

 cout<<"The shipping cost is: $"<<cost;  /*displays the value stored in cost variable of that else-if condition which evaluates to true */

}

Explanation:

Everything is well explained in the comments above. I will summarize it all.

The program takes the input weight from the user and checks the value of weight.

If and else-if conditions are used to check the value of weight.

if the value of weight is less than 0 or equal to 0 then invalid input is displayed.

Else the weight value is checked for the given ranges. && operator is used in each else if statement which is used to specify the range of the weight values the input weight should be in order to display the shipping cost.

For example take this statement: else if (weight > 0 && weight <= 1)

This statement checks the value entered by the user that if it lies in the range mentioned in this statement which is that the weight value should be greater than 0 AND less than or equal to 1. The value cannot lie above or below the given range in order for this condition to be true so && operator is used here.

If the weight entered by user exceeds 20 then the message is displayed:The package can not be shipped and the program exits. In JAVA System.exit(0) and in c++ exit(0) function is used to exit the program.

The output of both the programs is as following:

please enter the weight of the package: 3

The shipping cost is: $ 5.5
