Leer Challenge: Letter Counter | Fundamentals of Strings
C# Strings & Text Processing

bookChallenge: Letter Counter

In this chapter, you will deepen your understanding of string processing by taking on a practical challenge: counting the number of times a specific letter appears in a sentence, regardless of whether the letter is upper or lower case. This exercise builds on your experience with searching and counting occurrences in strings, but now requires you to handle case-insensitive comparisons. Being able to perform such operations is essential for many real-world text processing tasks, such as analyzing user input, validating data, or even building search features in applications.

Taak

  • Compare each character in sentence to letter in a case-insensitive manner.
  • Return the total number of matches found.
  • Only count occurrences where the character matches letter, regardless of case.
