I use scan only to know which index you wanna check, then use strcmp to compare 2 strings. In case they are not equal, we can also analyze and find out which string is lexicographically (lexicographic order means dictionary order, that is, the words which start from 'a' come before the words that start with 'b' and the earlier is lexicographically smaller than the later, we'll see about this later in the article) larger than the other by the various methods of string comparison in C. There are four methods for string comparison in C. The string library functions are pre-defined in string.h header file used to do operations on the strings.
