Translate a Low-Level Error into a Sensor Error

The provided readRaw(int slot) throws a std::out_of_range for a slot that does not exist. Callers should not have to know that detail, so catch it and throw your own error in its place (this is translating, not rethrowing):

- SensorError inherits from std::runtime_error; its explicit constructor takes a const std::string& message and passes it on - double readSensor(int slot): calls readRaw(slot) and returns its reading; if that throws std::out_of_range, throw SensorError with the text sensor , the slot number and unavailable instead

The tests read slot numbers from input, one per line, and print reading: and the value, or what() of the SensorError. They also catch std::out_of_range separately and print raw error escaped, which must never appear. For the first test the input is 0, 5, 3.

Do NOT write a main function.

Expected Output:

reading: 10.5↵
sensor 5 unavailable↵
reading: 42↵

= newline. The output ends with a newline — print one after the last line.
