C# C# Basics (Retired) Console I/O Formatting Output

Challenge Task 3 of 3 Use the concatenation operator + to append “ rocks!” to the end of the contents of the firstName

Challenge Task 3 of 3 Use the concatenation operator + to append “ rocks!” to the end of the contents of the firstName variable and print it to the screen using Console.WriteLine

I can not figure out what is wrong here.

I added a plus sign to append rocks;

here is the error:

StudentsCode.cs(8,0): error CS1525: Unexpected symbol firstName', expecting,', ;', or=' Compilation failed: 1 error(s), 0 warnings

CodeChallenge.cs
string firstName
firstName = "User";
Console.ReadLine();



Console.Write("You've entered ");
Console.Write(firstName);
Console.WriteLine(" rocks!");

Console.WriteLine("You've entered " + firstName + " rocks!");

your confused. the correct code is: string firstName = Console.WriteLine(); Console.WriteLine(firstName + “ rocks!”);

first u declare a variable named firstname which read user input and then u print it to the console.

Thankyou.
