Don't include assignments inside the ternary expression. Use the entire ternary as the right side of an assignment statement. A typical assignment with a ternary has this form:

  • variable = ( conditional_expression ) ? value_if_true : value_if_false ;

And be sure to remove the original "if" code when you replace it with the ternary assignment.
