C Program To Sort Names in Alphabetical Order
Learn How To Sort Names in Alphabetical Order in C Programming Language. This C Program To Arrange Names in Ascending Order makes use of Dynamic Memory Allocation.
This program takes in an input of Array of Characters, also known as Strings.The strcmp() method is used to compare two different strings. It not only compares the first or initial characters but the whole string. The strcpy() method copies the string from one location to another. The malloc() method used here allocates the requested memory by the User and returns a pointer to it.

This program works quite good and is very easy to understand. Can you tell me if there is library function to arrange the elements in alphabetical order automatically?
This is really an easy C program to print strings alphabetically. Thanks for this one.
without string function ,will you please explain ? using while loop only?
