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

This program takes 10 words(strings) from the user and sorts them in lexicographical order.

To solve this program, a two-dimensional string str is created.

This string can hold maximum of 10 strings and each string can have maximum of 50 characters (including null character).

To compare two strings, strcmp() function is used. Also, we used strcpy() function to copy string to a temporary string temp.

Output

Enter 10 words:
C
C++
Java
PHP
Python
Perl
Ruby
R
JavaScript
PHP

In lexicographical order:
