Write a function called order() thattakes three parameters, and rearranges the integers referred to sothat the largest is first, then the next largest, and finally thesmallest

The c++ program to implement order() method is given below.

#include <iostream>

using namespace std;

void order(int a, int b, int c);

int main() {

   int x, y, z;

   cout<<"This program displays numbers in descending order."<<endl;

   do

   {

       cout<<"Enter first number"<<endl;

       cin>>x;

       if(x<0)

           cout<<"Invalid input. Enter a positive number."<<endl;

   }while(x<0);

   do

   {

       cout<<"Enter second number"<<endl;

       cin>>y;

       if(y<0)

           cout<<"Invalid input. Enter a positive number."<<endl;

   }while(y<0);

   do

   {

       cout<<"Enter third number"<<endl;

       cin>>z;

       if(z<0)

           cout<<"Invalid input. Enter a positive number."<<endl;

   }while(z<0);

   order(x, y, z);

   return 0;

}

void order(int a, int b, int c)

{

   if((a>b)&&(a>c))

   {  

       cout<<"Numbers in decreasing order are"<<endl;

       cout<<a<<endl;

           if(b>c)

           {

               cout<<b<<endl;        

               cout<<c<<endl;

           }

           else

           {

               cout<<c<<endl;

               cout<<b<<endl;

           }

   }    

   if((b>a)&&(b>c))

   {  

       cout<<"Numbers in decresing order are"<<endl;

       cout<<b<<endl;

           if(a>c)

           {

               cout<<a<<endl;        

               cout<<c<<endl;

           }

           else

           {

               cout<<c<<endl;

               cout<<a<<endl;

           }

   }    

   if((c>b)&&(c>a))

   {  

       cout<<"Numbers in decreasing order are"<<endl;

       cout<<c<<endl;

           if(a>b)

           {

               cout<<a<<endl;        

               cout<<b<<endl;

           }

           else

           {

               cout<<b<<endl;

               cout<<a<<endl;

           }

   }

}

OUTPUT

This program displays numbers in descending order.

Enter first number

12

Enter second number

-9

Invalid input. Enter a positive number.

Enter second number

0

Enter third number

55

Numbers in decreasing order are

55

12

0

Explanation:

The method order() is declared as follows.

void order(int a, int b, int c);

The method is declared void since it does not return any value.

This program is designed to accept 0 and positive integers only. This is implemented by do-while loop while taking user input.

The program uses 3 integer variables to store the user input.

int x, y, z;

The method order() is designed to accept 3 integer parameters. This method is called once user enters valid input.

order(x, y, z);

These numbers are compared in order to display them in descending order.

No variable is used for comparison. The method simply compares the numbers and displays them using multiple if-else statements.

when listing items that have an order of priority.

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
