Greedy method in lexical analysis: each symbol should contain as many characters as possible 2. If the first character of an integer constant is 0, it is regarded as an octal value. 0100 = 64, not binary 3. printf ("Hello \ n"); with Char Hello [] = {'h', 'E', 'l', 'l', 'O ', '

main purpose is to separate the specific implementations of the abstract data types from their functions. The program must know what the operation is doing, but it's better if you don't know how to do it.tables, stacks, and queues may be three basic data structures in all computer science, and a large number of examples attest to their wide range of uses. In particular. We see how the stack is used to record procedures and function calls, and how recursion is actually implemented. It is importa
