Question

Write a program that will ask the user for three words (strings). Re-arranges them in ascending order by using a function (it should return void). Global variables are forbidden. Hint: You don't need to exchange the values among variables. You can just print them in the correct order. (C++ Please)

Example of Output:

Word 1: apple Word 2: orange Word 3: strawberry -------- orange apple strawberry

Answer 1

Program:

#include <iostream>

using namespace std;

void orderingWords(string word1, string word2, string word3) {
    // Ascending order of words by comparing given three words
    if (word1 <= word2 && word2 <= word3)
    {
        // Printing the ascending order of words
        cout << "Word1: " << word1 << endl;
        cout << "Word2: " << word2 << endl;
        cout << "Word3: " << word3 << endl;
    }
    else if (word1 <= word3 && word3 <= word2)
    {
        cout << "Word1: " << word1 << endl;
        cout << "Word2: " << word3 << endl;
        cout << "Word3: " << word2 << endl;
    }
    else if (word2 <= word1 && word1 <= word3)
    {
        cout << "Word1: " << word2 << endl;
        cout << "Word2: " << word1 << endl;
        cout << "Word3: " << word3 << endl;
    }
    else if (word2 <= word3 && word3 <= word1)
    {
        cout << "Word1: " << word2 << endl;
        cout << "Word2: " << word3 << endl;
        cout << "Word3: " << word1 << endl;
    }
    else if (word3 <= word1 && word1 <= word2)
    {
        cout << "Word1: " << word3 << endl;
        cout << "Word2: " << word1 << endl;
        cout << "Word3: " << word2 << endl;
    }
    else if (word3 <= word2 && word2 <= word1)
    {
        cout << "Word1: " << word3 << endl;
        cout << "Word2: " << word2 << endl;
        cout << "Word3: " << word1 << endl;
    }
}

int main()
{
    string word1, word2, word3;
    // Taking input for three words
    cout<<"Enter 3 words : ";
    cin >> word1 >> word2 >> word3;
    // Calling method for ordering words in ascending order
    orderingWords(word1, word2, word3);

    return 0;
}

Output:
