C# C# Objects Encapsulation and Arrays Ternary If

Can I please get help?

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".

I don't get this. Can I get help, Please?

CodeChallenge.cs 
int value = -1;
string textColor = null;

if (value < 0)
{
    textColor = "red";
}
else
{
    textColor = "green";
}

Perhaps this will help.

Here's a generic example of using the ternary:

SomeVariable = (test expression) ? value_if_true : value_if_false;

Can you get it from that, or do you have a more specific question?

int value = -1; string textColor = (value < 0) ? "red" : "green";
