Write a Program to Print Three Numbers in Descending Order: A Step-By-Step Guide

Let's say we have three numbers and need to sort them in descending order. How would we do that? Well, the answer is that we will use the if-else statement. Every high-level programming language supports if-else statements .

This programming tutorial will teach us how to print three numbers in descending order in various programming languages. The program we create needs to ask a user to enter 3 numbers. Then by using the if-else statement, we will sort the numbers in descending order.

Example

Input:11 13 10

Output:10 11 13

C Program to Print Three Numbers in Descending Order

#include<stdio.h>

intmain() 

{

int num1, num2, num3, small, smaller, smallest;



//input 3 numbers from user

printf("Enter 3 Numbers eg(13 4 14): ");

scanf("%d %d %d", &num1, &num2, &num3);



//for num1 is the greatest

if(num1>=num2 && num1>=num3)

{

if(num2>=num3)

{

printf("Descending: %d %d %d", num1, num2, num3);

}

else

{

printf("Descending: %d %d %d", num1, num3, num2);

}

} 

//for num2 is the greatest

elseif(num2>=num1 && num2>=num3)

{

if(num1>=num3)

{

printf("Descending: %d %d %d", num2, num1, num3);

}

else

{

printf("Descending: %d %d %d", num2, num3, num1);

}

} 

//for num3 is the greatest

else

{

if(num2>=num1)

{

printf("Descending: %d %d %d", num3, num2, num1);

}

else

{

printf("Descending: %d %d %d", num3, num1, num2);

}

}

return0;

}

Output

Enter 3 Numbers eg(13 4 14):13 4 14

Descending:14 13 4

C++ Program to Print Three Numbers in Descending Order

#include<iostream>

usingnamespace std;

intmain() 

{

int num1, num2, num3;



//input 3 numbers from user

cout<<"Enter 3 Numbers eg(13 4 14): "; cin>>num1>>num2>>num3;



//for num1 is the greatest

if(num1>=num2 && num1>=num3)

{

if(num2>=num3)

{

cout<<"Descending: "<<num1<<" "<<num2<<" "<<num3;

}

else

{

cout<<"Descending: "<<num1<<" "<<num3<<" "<<num2; 

} 

} 

//for num2 is the greatest

elseif(num2>=num1 && num2>=num3)

{

if(num1>=num3)

{

cout<<"Descending: "<<num2<<" "<<num1<<" "<<num3;

}

else

{

cout<<"Descending: "<<num2<<" "<<num3<<" "<<num1; 

} 

} 

//for num3 is the greatest

else

{

if(num2>=num1)

{

cout<<"Descending: "<<num3<<" "<<num2<<" "<<num1;

}

else

{

cout<<"Descending: "<<num3<<" "<<num1<<" "<<num2;

}

}

return0;

}

Output

Enter 3 Numbers eg(13 4 14): 13 4 14

Descending: 14 13 4

Python Program to Print Three Numbers in Descending Order

# input3 numbers from user

num1, num2, num3 =map(int, input("Enter 3 Numbers eg(13 4 14): ").split())

# for num 1 is the greatest

if(num1>=num2 and num1>= num3):

if(num2>=num3):

print(f"Descending: {num1} {num2} {num3}")

else:

print(f"Descending: {num1} {num3} {num2}")

# for num 2 is the greatest

elif(num2>=num1 and num2>= num3):

if(num1>=num3):

print(f"Descending: {num2} {num1} {num3}")

else:

print(f"Descending: {num2} {num3} {num1}")

# for num 3 is the greatest

else:

if(num2>=num1):

print(f"Descending: {num3} {num2} {num1}")

else:

print(f"Descending: {num3} {num1} {num2}")

Output

Enter 3 Numbers eg(13 4 14):13 4 14

Descending:14 13 4

Java Program to Print Three Numbers in Descending Order

import java.util.Arrays;

import java.util.Scanner;

public classDescendingOrder {

public static voidmain(String[] args) {

Scannerscanner = newScanner(System.in);

int[] nums = newint[3];

System.out.println("Enter three numbers:");

for (inti = 0; i < nums.length; i++) {

nums[i] = scanner.nextInt();

}

Arrays.sort(nums);

for (int i = nums.length - 1; i >= 0; i--) {

System.out.print(nums[i] + " ");

}

}

}

Output

Enter three numbers:

Wrapping Up

In this tutorial, we learned how to implement a program that prints three numbers in descending order in three different programming languages, namely C, C++, and Python. The algorithm of such a program is very simple.

First, we check for the largest number among the three values, and then in the nested if-else statement, we look for the second-largest number. The time and space complexity of the above program is constant because there are only three elements to sort.
