I think if string1>string2 it will return +ve.
string1<string it will return -ve.
string1=string it will return 0.

Actually there is a pointer function before strings. So if we give equal values to both strings but address are different, because strings are different.

@Sunder is right. It will return only 0 when both string are similar otherwise it will return 1 or -1.

If both the strings are equal then it returns 1 otherwise 0.

When you compare any two strings at that time compiler will return 0.

And this logic is used to find palindrome string.
