C#Help to understand the solution to the problem.

Question

he program you are given defines an array with 10 words and takes a letter as input.
Write a program to iterate through the array and output words containing the taken letter.
If there is no such word, the program should output "No match".

Sample Input
u

Sample Output
fun

My code:
using System;
using System.Linq;

namespace Задача_Слова_50хп
{
class Program
{
static void Main(string[] args)
{
string[] words =
{
"home",
"programming",
"victory",
"C#",
"football",
"sport",
"book",
"learn",
"dream",
"fun"
};
string letter = Console.ReadLine();

int count = 0;

//code here

foreach (string n in words)
{
if (words.Contains (letter))
{
Console.WriteLine(words);
}
else
{
Console.WriteLine("No match");
}
}
}

}
}

Answer 1

if (words.Contains (letter))

Should try this:

if (n.Contains (letter))

Answer 2

Next line. Console.WriteLine(n)

Answer 3

Outstanding. That if statement wasn’t in the original code. That’s why I didn’t see it. Glad you got it fixe.

Answer 4

Thnx. Works better, but still not true.

Answer 5

Thnx a lot. But right answer must be f.e.:
"n"
out:
fun
etc.
Now result is:
No match
No match
No match
No match
football
No match
No match
learn
No match
No match

Answer 6

I think need to use int count = 0. But how to use I don't know.

Answer 7

With your code that you provided, you need to change it like below. What you are doing in this code is:

For n in words —- That means “n” will be one of the words in the list. For the body of the loop, you want to examine one word, not all of them. So instead of using “words”, you use “n”. Then each iteration will use the next word from words as n. Notice all I changed was a couple of uses of “words” to “n”. The logic was fine. You only need to search a word, not the whole list.

foreach (string n in words)
{

if (n.Contains (letter))
{
Console.WriteLine(n);
}
else
{
Console.WriteLine("No match");
}
}

Answer 8

Yes, I tried to run the program with this code, but in the output I got the wrong result. I found a solution.
foreach (string n in words)
{
if (n.Contains(letter))
{
Console.WriteLine(n);
count++;
}
}

while (count == 0)
{
Console.WriteLine("No match");
}

Answer 9

As you can see, I used "count ++" and then after the "foreach" block I entered the "while" block with a condition. The clue for the correct solution of the problem was just in "count = 0". Thank you for your responses.

Answer 10

I'am so sorry, I put a mistake. Not "while" need to use "if".
