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.
Note, however, that although strings are reference types, they work rather more like value types. When one string is set to the value of another, eg string s1 = hello; string s2 = s1; Then s2 does at this point reference the same string object as s1.
