Final answer:
The switch construct can indeed be used with selection conditions other than integer expressions in many programming languages, making the statement false. For the GRASP CHECK, it is false that voltage is the same at every point in a wire in a circuit diagram, due to the resistance in real wires causing voltage drops.
Step-by-step explanation:
The statement that the switch construct can only be used when the selection condition reduces to an integer expression is false. While it is common to use integers with a switch statement, many programming languages such as Java and C# also support using enumerated types, characters, and sometimes strings as the selection condition in a switch statement. However, there are indeed some programming languages, like older versions of C, where the switch statement is more limited and typically requires an integer or an enumeration.
As for the GRASP CHECK:
True or false In a circuit diagram, we can assume that the voltage is the same at every point in a given wire. The answer is false. In an ideal circuit, voltage would be considered the same along a wire that has no resistance; however, in real-world circuits, wires do have some resistance, and there may be voltage drops along the wire especially when current is flowing.
