What does I† mean include boolean expression?
int value = -1; string textColor = null; return (value < 0) ? textColor = "red" : textColor = "green";
On the line which starts with return, you have what is called a ternary if statement. It is just a syntactically shorter way of writing a general if statement. The "?" acts as a "then", and the ":" acts as an "else".
