280 PointsCan't seem to figure out the last task of "Code Challenge: Formatting Output"
I've been trying to figure this one out for a bit, but can't seem to get it right. So i thought i would seek some help!
The Question is "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"
Please be nice on me :)
string firstName = Console.ReadLine();
Console.WriteLine(firstName);

Console.WriteLine(firstName);
So then if you "Use the concatenation operator + to append " rocks!" to the end...":
Console.WriteLine(firstName + " rocks!");

string firstName = Console.ReadLine();
firstName = firstName + " rocks!";
Console.WriteLine(firstName);

231,236 PointsIf you want to permanently modify firstName you could do it more concisely with a concatenation assignment operator:
firstName += " rocks!";

280 PointsThanks a lot, because of an earlier on the same subject i got confused and used two "+" signs, one on each side :x

41,120 PointsSteven - I actually tried that first on the code challenge, thinking it would work, and it failed for me:
string firstName = Console.ReadLine();
firstName += " rocks!";
Console.WriteLine(firstName);

231,236 PointsFor some reason, the challenge validator doesn't accept that, but it works fine in actual code! But I favor the solution that doesn't modify the variable, since the instructions are a bit ambiguous and the validator accepts it either way..
