Final answer:
To determine whether x is non-negative or y is negative, use the logical OR operator in an if statement with (x >= 0) || (y < 0) expression.
Step-by-step explanation:
To determine whether x is non-negative or y is negative, we can use the logical OR operator (||) in an if statement. The expression would be: (x >= 0) || (y < 0). This expression will evaluate to true if either x is non-negative or y is negative.
For example, if x = 0.0216 and y = -0.0224, the expression (0.0216 >= 0) || (-0.0224 < 0) would evaluate to true, since x is non-negative.
