1,815 PointsCorrect use of Ternary if statement
Are these two if statements equivalent? My code is not checking correctly. If askes me if I included the Boolean expression. I think I have included the boolean expression (value < 0). Any help would be appriciated!
int value = -1;
string textColor = null;
if (value < 0)
{
textColor = "red";
}
else
{
textColor = "green";
}
(value < 0) ? textColor = "red" : textColor = "green";

This answer worked! Thank you Reggie Williams!

1,815 PointsThank you Reggie Williams.
But, even when I compile my code as follows I do not pass the quiz.
int value = -1;
string textColor = null;
value < 0 ? textColor = "red" : textColor = "green";
Thanks again.

Treehouse TeacherHey Evan Welch that's a bit closer but instead of writing textColor more than once you can assign the value of the ternary operation to textColor
textColor = condition goes here ? "option if true" : "option if false";
Evan Welch
1,815 PointsOk, I think I see what you mean. So I would write:
int value = -1;
string textColor = value < 0 ? "red" : "green";
Right?

966 PointsWhy doesn't this challenge accept the exact formatting we were just taught?
(value < 0) ? textColor = "red" : textColor = "green";
Reggie Williams
Treehouse TeacherMichael Musch be sure to start a new thread when you have a question so it doesn't get lost but this challenge is asking you to initialize the value variable so you'll want to use the above format that acts as a single variable definition. The example you provided also requires writing textColor twice which goes against the concept of D.R.Y or don't repeat yourself

Treehouse TeacherEvan Welch you can shorten this code by assigning the result to textcolor that way you don't have to repeat anything and the result is stored in the variable
variable = condition < 0 ? "value1" : "value2";
