    gets() gets collects a string of characters terminated by a new line from the standard input stream stdin. The gets(str1) read the input string from user and store in variable str1. The gets(str2) read the input string from user and store in variable str2. The code i = strcmp(str1, str2); The strcmp not only returns -1, 0 and +1, but also other negative or positive values. So the value of i is "unpredictable integer value". printf("%d\n", i); It prints the value of variable i.
