Question 11 What would be the best statement about strcmp function in section 4.5? Group of answer choices Before comeing to the function s1 and s2 are null-terminated strings. The return value of the function indicates the following: The return value is 0 -- s1 is equal to s2; The return value -1 -- s1 is lexicographically before s2; The return value 1 -- s1 is lexicographically after s2. Before comeing to the function s1 and s2 are null-terminated strings. The return value of the function indicates the following: The return value is 0 -- s1 is equal to s2; The return value 1 -- s1 is lexicographically before s2; The return value -1 -- s1 is lexicographically after s2. Before comeing to the function s1 and s2 are null-terminated strings. The return value of the function indicates the following: The return value is 0 -- s1 is equal to s2; The return value > 0 -- s1 is lexicographically before s2; The return value < 0 -- s1 is lexicographically after s2. Before comeing to the function s1 and s2 are null-terminated strings. The return value of the function indicates the following: The return value is 0 -- s1 is equal to s2; The return value < 0 -- s1 is lexicographically before s2; The return value > 0 -- s1 is lexicographically after s2.

Introduction
Strcmp function:
'strcmp' is a standard library function in the C programming language that compares two strings lexicographically and returns an integer indicating their ordering. The function compares each character of the two strings 's1' and 's2' starting from the first character. If a difference is found, the function returns the difference between the ASCII values of the two characters, indicating that 's1' is lexicographically before 's2' (negative value) or after 's2' (positive value). If all characters are the same, the function returns 0, indicating that 's1' and 's2' are equal. Before entering the function, 's1' and 's2' are null-terminated strings, which means that they end with a special null character '\0'.
