Answer:
I am writing a C++ and JAVA program.
import java.util.Scanner; //for using input output functions
public class LabProgram { // class name
public static void main(String[] args) {//start of main function body
Scanner input = new Scanner(System.in);
// creates input instance of Scanner type
String str; // declares String type variable str for a string value
int num; // declares integer type variable num to hold an integer value
str = input.next(); //scans and reads input string from user
num = input.nextInt(); //scans and reads input integer from user
//while loop continues to execute until user enters quit 0
while(str!="quit" && num!=0) {
/* prints the following message, for example if value of num = 2 and value of str = apples then the following print statement prints Eating 2 apples a day keeps the doctor away. */
System.out.println("\nEating " + num +" " + str + " a day keeps the doctor away.");
//takes string and integer as input again and keep taking input until user //enters quit 0
str = input.next();
num = input.nextInt(); } } }
Explanation:
The program is well explained in the comments mentioned with each statement of the program. The program simply prompts user to enter a string and an integer. The while loop keeps executing until user enters quit 0. The program keeps taking input string and integer from user and prints the message System.out.println("\nEating " + num +" " + str + " a day keeps the doctor away."); The loop breaks when the use enters quit 0. The screenshot of the program along with its output is attached.
Answer:
Following are the code to the given question:
#include <iostream>//header file
using namespace std;
int main()//main method
{
int first = 0,second = 0,third = 0;//defining integer variable
int temp; //defining integer variable
const string SENTINEL = "done"; // defining a string variable as constant
string repeat;// defining a string variable
bool notDone = true; //defining bool variable
cout << "Enter first number: ";//print message
cin >> first;//input value
cout << "Enter second number: ";//print message
cin >> second;//input value
cout << "Enter third number: ";//print message
cin >> third;//input value
while(notDone == true)//defining a loop to check the value
{
if(first > second)//use if to compare first and second value
{
int temp = first;//defining temp to hold first value
first = second;//holding second value in first variable
second = temp;//holding temp value in second variable
}
if(second > third)//use if to compare second and third value
{
int temp = second;//defining temp to hold second value
second = third;//holding second value in third variable
third = temp;//holding temp value in third variable
}
cout << "Smallest: " << first << endl;//print smallest value
cout << "Next smallest: " << second << endl;//print Next smallest value
cout << "Largest: " << third << endl;////print Largest value
cout << "Enter any letter to continue or done to quit: ";//print message
cin >> repeat;//holding string value
if (repeat == SENTINEL)
{
notDone = false;//holding bool value
}
else //else block
{
cout << "Enter first number: ";//print message
cin >> first;//input value
cout << "Enter second number: ";//print message
cin >> second;//input value
cout << "Enter third number: ";//print message
cin >> third;//input value
}
return 0;
}
}
Output:
Please find the attached file.
Explanation:
- Inside the main method Four integer variable "first, second, third, and temp" is declared in which first three variable is used for input value and temp is used to compare value.
- In thew next step, two string variable "SENTINEL and repeat" is declared in which "SENTINEL" is constant and a bool variable "notDone" is declared.
- After input the value from the user-end a loop is declared that compare and swap value and print its value.
