2,842 Pointsternary if- c#
In the previous video, we saw how a ternary if statement could be used in place of an if/else statement to determine the value to return from a method. Ternary if statements can also be used to determine the value to use when initializing a variable. Use a ternary if statement instead of an if/else statement to initialize the textColor variable to the string value "red" if the value variable is less than "0", otherwise initialize the textColor variable to the string value "green".
WHERE DID I GET WRONG?
int value=-1;
string textColor = null;
textColor = (value < 0 ) ? {"red"}:{"green"} ;

3,338 PointsBecause you are already assigning whats on the right, to the left. You do not have to do it again inside the ternary if. Also, the syntax is wrong. The comparison argument comes before the question mark, then the result upon a true comparison, then a colon, and the result upon a false comparison at the end.
