1. In Curses:

1. What is stdscr?
2. What is a pad?
3. How can you write "Hello World" to stdscr?
4. How can you write "Hello World" to a pad?
5. How do you get information written to stdscr or to a pad actually to appear on the user's screen?

2. Write a complete program that uses a dispatch table to implement the following algorithm:

• The program prompts the user to enter a word. If the word the user types matches one of the names in the dispatch table, the corresponding function is called. Otherwise the program issues an error message and doesn't call a function.
• The functions in the dispatch table take no arguments, and return a float. The program prints the value of the returned float when the function returns.
• The program runs forever. (Presumably, one of the functions will call exit().)
• Do not write the code for any of the functions.
• Do everything in main().
• Write the code so that the dispatch table can be expanded easily without affecting the statements used to search the table.
• Set up the dispatch table so that it associates the following names and functions:

3. Relate each of the syntactic elements of a URL to the process of obtaining a document from a World Wide Web server. Include an explanation of how the functions gethostbyname(), connect(), write(), and read() would be used.
