#include <iostream>
using namespace std;
int main()
{
    string word[10], temp;
    cout << "Insert 10 words: " << endl;
    for(int x = 0; x < 10; ++x)
    {
        getline(cin, word[x]);
    }
    for (int x = 0; x < 9; ++x)        
    // Bubble Sort
    {
        for (int y = 0; y < 9 - x; ++y)
        {
            if (word[y] > word[y + 1]) 
            {
                temp = word[y];
                word[y] = word[y + 1];
                word[y + 1] = temp;
            }
        }
    }
    cout << "\nIn lexicographical order: " << endl;
    for(int x = 0; x < 10; ++x)
    {
       cout << word[x] << endl;
    }
    return 0;
}

  • User can arrange a list of words in lexicographical order. 10 words are entered by the user.
  • To store the entries of the user, a string object array is created.
  • Bubble sort algorithm is used to process the lexicographical order.
  • It compared the words 1 by 1 and places them in an alphabetical order.
  • The result is displayed on the screen.
