Answer:

No, Only the value between 100 and 200 can not test the code correctly.
This code snippet ensures that the cost value is between 100 and 200.

Explanation:

The above code has three condition test- if, else-if and else.
The first condition is true for the value which is a minimum of 100.
The else if condition is true for the value which is maximum from 200.
Then the else condition is used when the if and else if condition is false.
when the user gives the value between 100 and 200 then it will test that the value lies between 100 or 200.
To test the whole scenario there must be one value is less than 100 and greater than 200.

allsm [11]

Answer:

#include <iostream>

using namespace std;

int main()

{

float altitude;

cout<<"Enter alttitude in meter";

cin >>altitude;

if(altitude<0 || altitude > 50000)

{

cout<<"Invalid value entered";

return 0;

}

else{

if(altitude<= 10000)

{cout <<"In troposphere "<<endl;}

else if(altitude>10000 && altitude<=30000)

{cout <<"In lower stratosphere"<<endl;}

else if(altitude>30000 && altitude<=50000)

{cout <<"In upper stratosphere"<<endl;}

}

return 0;

}

Explanation:

Define a float type variable. Ask user to enter altitude in meters. Store value to altitude variable.

Now check if value entered is positive and less than 5000,if its not in the range of 0-50,000 display a termination message and exit else check if it's in less than 10000, in between 10000 and 30000 or in between 30000 and 50000.

10,000 is above sea level is troposphere.

10,000-30,000 is lower stratosphere.

30,000-50,000 is upper stratosphere.

Juan, a network user, sends an email to you, the IT admin of the network, stating that his account is locked because he has lost

slamgirl [31]

Answer:

The correct answer to the following question is Option D.

Explanation:

Already when we authorize an individual to set up a new credential or provide a provisional code or password, we must make ensure that the person is checked. We could allow a verification code after confirming the consumer.

Verification remains crucial because an imposter may try to compromise to provide a temporary credential or switch his password by posing as a further person.
So, Juan fixes his problem by making sure whether resetting the password has always been allowed by checking that Juan is the one that he claims he is.

Explain in two or three sentences why health science careers are among the fastest growing careers in

il63 [147K]

Answer:

The growing concern of health science professionals and their limited number has caused students to opt for the courses in the U.S.

Explanation:

Health science professions account for more than half of the top twenty major growing occupations worldwide. According to the survey in 2018, it was estimated that by 2020 the United States would need around six million additional healthcare employees. And in the present scenario of the Coronavirus pandemic, it has been increased incredibly. And therefore more educational institutes are providing programs to assist students to prepare for health science careers.

In this exercise you will debug the code which has been provided in the starter file. The code is intended to take two strings,

vampirchik [111]

Answer:

Here is the corrected program:

import java.util.Scanner; //to accept input from user

public class 02_14_Activity_one { //class name

public static void main(String[] args) { //start of main method

Scanner scan = new Scanner(System.in); //creates Scanner class object

System.out.println("Enter first string"); //prompts user to enter first string

String s1 = scan.nextLine(); //reads input string from user

System.out.println("Enter second string"); //prompts user to enter second string

String s2 = scan.nextLine(); //reads second input string from user

System.out.println("Enter number of letters from each word"); //enter n

int n = scan.nextInt(); //reads value of integer n from user

System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));

} } //uses substring method to print a string made up of the first n letters of s1 and the last n letters of s2.

Explanation:

The errors were:

Scanner scan = Scanner(System.in);

Here new keyword is missing to create object scan of Scanner class.

Corrected statement:

Scanner scan = new Scanner(System.in);

String s1 = nextLine();

Here object scan is missing to call nextLine() method of class Scanner

Corrected statement:

String s1 = scan.nextLine();

String s2 = Scanner.nextLine();

Here class is used instead of its object scan to access the method nextLine

Corrected statement:

String s2 = scan.nextLine();

String n = scan.nextLine();

Here n is of type String but n is a whole number so it should be of type int. Also the method nextInt will be used to scan and accept an integer value

Corrected statement:

int n = scan.nextInt();

System.out.println(s1.substring(1,n-1) + s2.substring(s1.length()-n));

This statement is also not correct

Corrected statement:

System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));

This works as follows:

s1.substring(0,n) uses substring method to return a new string that is a substring of this s1. The substring begins at the 0th index of s1 and extends to the character at index n.

s2.substring(s2.length() - n ) uses substring method to return a new string that is a substring of this s2. The substring then uses length() method to get the length of s2 and subtracts integer n from it and thus returns the last n characters of s2.

The screenshot of program along with its output is attached.
