Hey everyone!
Here is my solution to the challenge from the C# Tutorial 05 (Arrays) video that is out soon.
Have fun with it! 😀
using System;
namespace My_Awesome_Program
{
class Program
{
static void Main(string[] args)
{
Console.Write("How many students are in your class: ");
int studentCount = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Please input the names of the students: ");
string[] students = new string[studentCount];
for (int i = 0; i < studentCount; i++)
{
students[i] = Console.ReadLine();
}
Console.WriteLine("--------------");
Array.Sort(students);
for (int i = 0; i < studentCount; i++)
{
Console.WriteLine(students[i]);
}
// Wait before closing
Console.ReadKey();
}
}
}

Here is mine.
using System; namespace Awesome_Projects { class Program { static void Main(string[] args) { Console.Title = "FRIDAY"; Console.Write("Number of students in class: "); int studentNumber = Convert.ToInt32(Console.ReadLine()); string[] studentname = new string[studentNumber]; //Creating Array Console.WriteLine("Enter the names:"); for (int i = 0; i < studentname.Length; i++) //Array Input { studentname[i] = Console.ReadLine(); } Console.WriteLine("\nThe names in alphabatical order:"); Array.Sort(studentname); //Sorting for (int i = 0; i < studentname.Length; i++) //Array Output { Console.WriteLine(studentname[i]); } Console.ReadKey(); // Wait before closing } } }Hey Here is Mine

i managed to use list 😅
using System; using System.Collections.Generic; namespace Arrays_or_List { class Program { static void Main(string[] args) { Console.Write("Number of students to register: "); int number = Convert.ToInt32(Console.ReadLine()); List<string> studentList = new List<string>(); Console.WriteLine("Write names: "); for (int i = 0; i < number; i++) { Console.Write(i+1 + ".

"); Console.WriteLine(studentList[n]); } Console.ReadKey(); } } }I have to fix some stuff on my code.
With Arrays
using System; using System.Collections.Generic; using System.ComponentModel; namespace CS_Practice { class Program { static void Main(string[] args) { Console.WriteLine("Enter number of students: "); int no = Int32.Parse(Console.ReadLine()); string[] students = new string[no]; for (int i = 0; i < students.Length; i++) { Console.WriteLine(i + 1 + ". Enter student name"); students[i] = Console.ReadLine(); } Array.Sort(students); Console.WriteLine("\n---------------------"); Console.WriteLine("Here are students sorted alphabetically:"); for (int i = 0; i < students.Length; i++) { Console.WriteLine(i + 1 + ". " + students[i]); } Console.WriteLine("Enter any key to exit"); Console.ReadKey(); } } }With Lists:
using System; using System.Collections.Generic; using System.ComponentModel; namespace CS_Practice { class Program { static void Main(string[] args) { List<string> students = new List<string>(); while (true) { Console.WriteLine("Enter student's name, write q to quit: "); string name = Console.ReadLine(); if(name == "q") { break; } students.Add(name); } students.Sort(); Console.WriteLine("\n----------------------"); Console.WriteLine("Here are students names sorted alphabetically"); for(int i=0; i<students.Count; i++) { Console.WriteLine(i+1 + ".

//Question.. And i did not use write function because i use it when i need to color but as you can see just a few codes on top of it you'll see i already changed to the color i wanted so.....

Also did a version using List
[code]
using System;
using System.Collections.Generic;
namespace My_Awesome_Program
{
class Program
{
static void Main(string[] args)
{
Console.Write("how many students are in your class?: ");
int studentCount = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Please input the names of the students: ");
List<string> studentList = new List<string>();
for (int i = 0; i < studentCount; i++)
{
studentList.Add(Console.ReadLine());
}
studentList.Sort();
for (int i = 0; i < studentList.Count; i++)
{
Console.WriteLine((i+1) + ". " + studentList[i]);
}
// wait before closing
Console.ReadKey();
}
}
}
[/code]
This is my version. I also added a solution in which instead of a number we enter the word :)
Heres my solution for the challenge!
{
Console.Title = "ALPHEBETIC ORDER CONVERTER";
Console.Write("How many students are in your class : ");
string[] list_students = new string[Convert.ToInt32( Console.ReadLine())] ;
Console.WriteLine("\nList the students\n-----------------------");
for (int i=0;i < list_students.Length;i++ )
{
list_students[i] = Console.ReadLine();
}
Array.Sort(list_students);
Console.WriteLine("Heres your sorted list of students");
for (int i = 0; i < list_students.Length; i++)
{
Console.WriteLine(list_students[i]);
}
Console.ReadKey();
}
}
}
This is my solution, not too different to brackeys.

first attempt, struggled a little but i got it working
using System;
using System.Collections.Generic;
namespace My_Awesome_Program

class Program
{
static void Main(string[] args)
{
Console.WindowHeight = 40;
Console.WindowWidth = 100;
Console.Write("How Many Students Are In Your Class?: ");
int numOfStudents = Convert.ToInt32(Console.ReadLine());;
Console.WriteLine("What are their name?: ");
string[] names = new string[numOfStudents];
for (int i = 0; i < names.Length; i++)
{
names[i] = Console.ReadLine();
}
Console.WriteLine("----------------------------");
Array.Sort(names);
Console.WriteLine("Here they are alphabeticaly");
for (int i = 0; i < names.Length; i++)
{
Console.WriteLine(names[i]);
}
// Wait before closing
Console.ReadKey();
}
}
}
Aarhhg!!! I don't get it can somebody explain me plz...
heres mine i added a total feature
using System;
using System.Collections.Generic;
namespace Array
{
class Program
{
static void Main(string[] args)
{
Console.Title="Wayne's Array";
//Getting them to write how many students in class
Console.ForegroundColor = ConsoleColor.Yellow;
Console.Write("How many Students are in your class: ");
Console.ForegroundColor = ConsoleColor.Green;
int studentCount = Convert.ToInt32(Console.ReadLine());
//student names input
Console.ForegroundColor = ConsoleColor.Yellow;
Console.WriteLine("Please input the names of your students: ");
string[] students = new string[studentCount];
for (int i = 0; i < students.Length; i++)
{
Console.ForegroundColor = ConsoleColor.Green;
students[i] = Console.ReadLine();
}
//Students result alphabetically
Console.ForegroundColor = ConsoleColor.Cyan;
Console.WriteLine("\nHere are you students alphabetically:");
System.Array.Sort(students);
for (int i = 0; i < students.Length; i++)
{
Console.ForegroundColor = ConsoleColor.Green;
Console.WriteLine(students[i]);
}
Console.WriteLine("Total of: " + studentCount + " Students.");
//Wait before Closing
Console.ReadKey();
}
}
}
namespace MyProgramAsANoob
{
class Program
{
static void Main(string[] args)
{
Console.ForegroundColor = (ConsoleColor.Green);
Console.WriteLine("How many students are in the class?: ");
string[] students = new string [Convert.ToInt32(Console.ReadLine())];
Console.WriteLine("Please type their names here: ");
for (int i = 0; i < students.Length; i++)
{
students[i] = Console.ReadLine();
}
Console.WriteLine("--------------");
Console.ForegroundColor = (ConsoleColor.Yellow);
Array.Sort(students);
for (int i = 0; i < students.Length; i++)
{
Console.WriteLine(students[i]);
}
//Wait Before Closing
Console.ReadKey();
}
}
}
So when i tried to do this I didn't specifically make a new int.
Ex. string[] students = new string [Convert.ToInt32(Console.ReadLine())];
Could this cause an issue? The program ran fine and did what it was supposed to do but i'm just curious whether this is a mistake or just another method?
// Here is my program! yay!
//Pretty spot on to our solution, all that's different is I chose to have the list displayed in yellow for emphasis :)
//Thanks teach'!
using System;
namespace How_Many_Kids_Programs

int numberOfKids = Convert.ToInt32(Console.ReadLine());
string[] children = new string[numberOfKids];
Console.WriteLine("\nThank You.\nNow please write each pupils name, followed by the 'Return' key: \n");
for (int i = 0; i < children.Length; i++)
{

//Making an Array
string[] students = new string [s];
Console.WriteLine("Ok Great!!\nNow Enter The Names Of The Students And I'll Sort Them In Alphabetical Order");
for (int i = 0; i < students.Length; i++)

Array.Sort(students);
for (int i = 0; i < students.Length; i++)
{
Console.WriteLine(students[i]);
}
//pause
Console.ReadKey();
}
}
}
I used Lists and made taking names end when "..." is inputted instead of asking how many student to input.
class Program
{
static void Main(string[] args)
{
string input = null;
Console.WriteLine("Please enter the name of the students.\nNOTE: Type '...' and press Enter when you finish typing all of the students.");
List<string> studentList = new List<string>(); //Student List
while (input != "...")
{
input = Console.ReadLine();
if (input != "...")
{
studentList.Add(input);
}
}
studentList.Sort();
Console.WriteLine("---------------------\nHere they are alphabetically:");
for (int i = 0; i < studentList.Count; i++)
{
int order = i + 1;
Console.WriteLine(order + ". " + studentList[i]);
}
Console.ReadKey(); // Do not close the Console
}
}
Tow solutions, one w/ Lists and other w/ Arrays .
using System;
namespace lists
{
class Program
{
static void Main(string[] args)
{
// Main
string[] students = new string[4];
Console.WriteLine("Type your students names:");
for (int i = 0; i < students.Length; i++)
{
students[i] = Console.ReadLine();
}
Console.WriteLine("-------------");
Array.Sort(students);
for (int i = 0; i < students.Length; i++)
{
Console.WriteLine(students[i]);
}
// Closing
Console.ReadKey();
}
}
}
This is my answer...
Console.Title = "Teachers Program";
Console.ForegroundColor = ConsoleColor.Red;
Console.Write("How many in your class?: ");
Console.ForegroundColor = ConsoleColor.White;

Console.WriteLine("What are they're names?");
Console.ForegroundColor = ConsoleColor.White;
