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?

Answer 1

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");
}

Answer 2

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

Answer 4

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.

Answer 5

🅘🅜 🅰🅹 !!! So how it do? On code level

Answer 6

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..

Answer 7

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");
}

}
}
}

Answer 8

int noMatch = 0;
bool match = false;

while (count < words.Length)
{
if (words[count].Contains(letter))
{
Console.WriteLine(words[count]);
match = true;
}
else if (!words[count].Contains(letter))
{
noMatch++;
}
count++;
}
if(noMatch > 0 && match is false) { Console.WriteLine("No match"); }
