C# words with needed letters ?

https://code.sololearn.com/caV3vX3MMaQM/?ref=app We have a code. If the entered letter is in the word/words you need to output they, if not - output “No match”. This code do it, but if have/not letter - app output many times “no match” What is wrong?

Nazar Sumyk Here is the solution int count = 0; foreach (string word in words) { if (word.Contains(letter)) { Console.WriteLine(word); count++; } } if(count == 0) { Console.WriteLine("No match"); }

Nazar Sumyk You printed matched word inside loop but didn't increase count. So increase count also inside if condition and outside the loop check if count is 0 then print "No match". For example: Inside the loop check: if (words[I].Contains(word)) { Console.WriteLine(word); count++; } Outside the loop check if (count == 0 ) { Console.WriteLine("No match"); }

Nazar Sumyk Don't print inside loop. Just increase count when string matched and check count outside the loop. So if count is greater than 0 then print Match otherwise print no match. Edited: Print no match if count is 0

The no match indicates that the word doesn't match the condition. If there are multiple words don't match, multiple no match will be outputed.

When you say a letter you mean a single letter? Becouse as it is written the code allow you to write a entire sentence...If yes I would change the type of the input to char (not string)...If not then you need to check each letter of the input..

If count remains 0 the loop never detected the letter while looping in the for each iterations. If the letter is found the word will be wrote to the console, & count increments therefore not writing “No match” to the console. string letter = Console.ReadLine(); int count = 0; foreach(var word in words) { if(word.Contains(letter)) { Console.WriteLine(word); count += 1; } } if(count == 0) { Console.WriteLine("No match"); } } } }
