Lexicographical Order in C language

 

This code is a C program that sorts a given number of strings in lexicographical order. It begins by asking the user to enter the number of strings. Then, it prompts the user to input each string one by one. After obtaining all the strings, it uses nested loops and the `strcmp` function to compare and sort the strings in lexicographical order. Finally, it prints the sorted strings to the console. The code utilizes the standard libraries `stdio.h`, `stdlib.h`, and `string.h` for input/output operations, memory allocation, and string manipulation, respectively.
