Unplug the refrigerator. Mark the wires so you know where they go into the switch. Take out the switch and tube. Go to an appliance parts store with the switch and tube and the model and serial number of the refrigerator and get a new part. Do not kink, bend, or fold the new tube as you carry it home or install it.
Write your question here. Hey. I know a lot of people talk about the difference between C-String and String. C-String is a sequence of chars stored in an array followed by a vector, and String is an object where a sequence of chars are stored in a vector.
Object references (and not the actual object): concat copies object references into the new array. Both the original and new array refer to the same object. That is, if a referenced object is modified, the changes are visible to both the new and original arrays. This includes elements of array arguments that are also arrays. Strings, numbers and booleans (not String, Number, and Boolean objects): concat copies the values of strings and numbers into the new array.
