C++ Program to Sort Elements in Lexicographical Order (Dictionary Order)

This program takes 10 words from the user and sort them in lexicographical order.


Example: Sort Words in Dictionary Order

#include 
using namespace std;

int main()
{
    string str[10], temp;

    cout << "Enter 10 words: " << endl;
    for(int i = 0; i < 10; ++i)
    {
      getline(cin, str[i]);
    }

    for(int i = 0; i < 9; ++i)
       for( int j = i+1; j < 10; ++j)
       {
          if(str[i] > str[j])
          {
            temp = str[i];
            str[i] = str[j];
            str[j] = temp;
          }
    }

    cout << "In lexicographical order: " << endl;

    for(int i = 0; i < 10; ++i)
    {
       cout << str[i] << endl;
    }
    return 0;
}

To solve this program, an array of string object str[10] is created.

The 10 words entered by the user is stored in this array.

Then, the array is sorted in lexicographical order using nested for loop and displayed on the screen.
