C# Lesson 2 – Basic Input and variables

Create a new console project called BasicInput

Enter the following code inside the main function

static void Main(string[] args) { //declare username as a variable String username; //output request Console.WriteLine("Enter Your Name: "); //get name from user username = Console.ReadLine(); //ouput message and name Console.WriteLine("Hello " + username); //prevents program from exiting straight away Console.ReadLine(); }

 

 

String username declares a variable called username of type string. This will allow us to store any character on the keyboard: numbers, symbols and letters.

Example1: “Joe Bloggs”

Example2: “1234”

Example3: “Joe@email.com”

Note: 123 + 456 = 579, However “123” + “456” = “123456”

Adding Strings together is called concatenation

 

username = Console.ReadLine() The input from the user is then stored in the variable user name

 

Console .WriteLine( "Hello " + username) Adds the word “hello” to the string “username”
