If characters are not equal line 09 or we reach the end of the string line 11 , then the while loop is a break. After the while loop, we check both the string traversals are reached to the end or not line If the traversal is reached to the end of both strings, then the strings are equal otherwise not.
The following library functions can be used for string comparison. All the functions are declared in the string. Return value: Return 0 if the strings are equal.
Return a negative integer if the ASCII value of the first unmatched character of the first string is less than the second string. Return a positive integer if the ASCII value of the first unmatched character of the first string is greater than the second string. Some systems return difference of the ASCII value of first mismatched character and some systems return -1 if the ASCII value of the first unmatched character of the first string is less than the second string and return 1 if the ASCII value of the first unmatched character of the first string is greater than the second string.
As an example: char name[32]; The name array is null string. So how can you tell the difference between an empty string and a null string? The strcmp function at Line 9 compares the two char arrays.

Computer Organization. Discrete Mathematics. Why not show the whole program that, when run, shows the result you're seeing? Use semicolons, a main , etc. How come your compiler is not throwing warning while using double quotes in char two? It isn't a pointer. You should print the strings after you get them and after you sanitize them to help you debug. Your fifteen ones "" is actually 16 characters once you include the terminating null so the strcpy will overflow pass. Show 2 more comments.
