C#.I need your help!

Question

In this program if string letter exists in the array words it displays the word containing the letter. How can I make the program to output "No match" one time if the letter is not exist in the all array?

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;
for(count=0; count<10; count++) {

if(words[count].Contains(letter)) Console.WriteLine(words[count]); }

}
}

//your code goes here

}

Answer 1

Well you can have a boolean variable which is set to false by default . And you can set it to true in the if statement in the for loop ( if your program finds the word the boolean will be set to true ) . You can check if the boolean is false with an if statement OUTSIDE the loop and if it was false you can output no match.

here is how i did it

You shouldn't be using and modifying variable <count> in the for...loop. You should instead create and use another variable dedicated as the loop counter. The only time when you should modify (increment) <count> is when you found an array <words> element that contains <letter>.

Once you're finished with the loop, you go use `if` conditional to verify whether <count> value was zero which indicates no match was found And when <count> was actually zero, you go print that "No match" on the screen.

Thanks a lot...I finally managed to solve it, with your help!!!

Answer 4

I tried the ! Operator but it displays the message "No match" for every index not including the letter. I just want to do this only one time if the letter is not included in the 10 indexes!
