How would you use a switch statement in Go to evaluate non-constant expressions?
- switch x := someNonConstantExpression(); x { case 1: // Handle if x is 1 case 2: // Handle if x is 2 default: // Handle other cases }
- switch x { case 1, 2, 3: // Handle specific values case "hello", "world": // Handle specific strings default: // Handle other values }
- switch x.(type) { case int: // Handle integer case string: // Handle string default: // Handle other types }
- switch { case x < 0: // Handle if x is negative case x == 0: // Handle if x is zero case x > 0: // Handle if x is positive }
To evaluate non-constant expressions in a switch statement in Go, you can use a switch statement without a condition, like switch { ... }. Each case can then specify a condition to evaluate. This allows you to perform dynamic case matching based on non-constant expressions.
