Splitting string is a very common operation, especially in text based environment like – World Wide Web or operating in a text file. Zero, with no non-zero bit, returns 0. A signed integer just uses one of the bits as a sign, so an 8 bit unsigned can store 0-->255, and an 8 bit signed -127-->127 because one bit is used as a sign. A class is a collection of variables and functions working with these variables.
