C#.NET — Determine the correct output for the code: String s1 = "Kicit"; Console.Write(s1.IndexOf('c') + " "); Console.Write(s1.Length);

Introduction / Context:
This program evaluates two string operations: finding the index of a character and retrieving the length of the string. It checks whether the learner understands zero-based indexing in C#.NET strings and how IndexOf works.

Given Data / Assumptions:

• s1 = "Kicit"
• Method call: s1.IndexOf('c')
• Property: s1.Length

Concept / Approach:
Strings in C# are zero-based, meaning the first character is at index 0. IndexOf returns the index of the first occurrence of a given character or substring. Length returns the number of characters in the string.

Step-by-Step Solution:

Verification / Alternative check:
Test in a C# REPL or Visual Studio project confirms IndexOf('c') == 2 and Length == 5. Output matches expectation.

Why Other Options Are Wrong:
(a) and (c) suggest incorrect index or length. (d) assumes length 6, which is wrong. (e) assumes 7, which is also wrong.

Common Pitfalls:
Counting indices from 1 instead of 0 or mistaking Length as the last index rather than number of elements.
