Question

Which of these methods is used to compare two strings such that after comparison output returns different integer values as (0 for false, 1 for true)?

(a) Equals ()

(b) == operator

(c) Compare()

(d) None of the mentioned

I have been asked this question in an online interview.

Asked question is from Comparison of Strings topic in section Arrays and Strings of C#

Answer 1

The correct option is (c) Compare()

Easiest explanation - The comparison is case sensitive in nature and hence different integer values are returned for different conditions as under:

             1. zero integer (0), if string s1 equal to string s2.

             2. positive integer(+1), if string s1 greater than s2.

             3. Negative integer(-1), if string s1 is less than s2.
