{
class Program
{
static void Main(string[] args)
{
string[] words = {
"home",
"programming",
"victory",
"C#",
"football",
"sport",
"book",

int count = 0;

//your code goes here
foreach (var i in words)
{
if(words[i].Contains(letter))

Console.Write("No match");
}

}

Here var i, is of type String and you're doing words[i] , treating i as an int where i is actually a String.

Write,
i.Contains(letter)
.
.
Console.WriteLine(i)

Answer 2

Try this .

using System;
using System.Collections.Generic;

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

string letter = Console.ReadLine();

string mensaje = "";
for(int i = 0; i < words.Length;i ++)
{
if(words[i].Contains(letter))
{
mensaje += words[i] + "\n\r" ;
}

}
if (mensaje == "")
{
mensaje = "No match";
}
Console.Write(mensaje);

}
}
}

Hi guys!

Here is my solution using foreach!
using System;
using System.Collections.Generic;

namespace Code_Coach_Challenge
{
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;

foreach(string w in words)
{
if (w.Contains(letter))
{
Console.WriteLine(w);
count++;
}

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

Answer 6

Words

The 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

using System;

{
string[] words = {
"home",
"programming",

"sport",
"book",
"learn",
"dream",
"fun"
};

string letter = Console.ReadLine();

int count = 0;

//your code goes here
for(int i=0;i<words.Length;i++){
if(words[i].Contains(letter)){
Console.WriteLine(words[i]);
count++;
}

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