 strcmp()                Compare Two Strings, Case Sensitive

 #include   <string.h>                   Required for declarations only

 int        strcmp(string1,string2);
 const char *string1;                    First string
 const char *string2;                    Second string

    strcmp() performs a lexicographic comparison of 'string1' and
    'string2' ('a' is less than 'b', 'b' is equal to 'b', 'c' is greater
    than 'b', and 'A' is less than 'a').

    Returns:    A value indicating the relationship between the two
                strings:

                      Comparison          Returned

                'string1' <  'string2'      < 0
                'string1' == 'string2'        0
                'string1' >  'string2'      > 0

      Notes:    strcmp() expects to operate on null-terminated strings.

   -------------------------------- Example ---------------------------------

    This example finds the string that sorts first (alphabetically) and
    prints the strings accordingly:

           #include <string.h>
           #include <stdio.h>               /* for printf */

           char str1[20], str2[20];
           int order;

           main()
           {
               strcpy(str1,"alligator");
               strcpy(str2,"albatross");
               if ((order = strcmp(str1,str2)) <= 0)
                   printf("1. %s     2. %s  \n", str1,str2);
               else
                   printf("1.  %s     2. %s  \n",str2,str1);
           }
