Program Plan Intro
Port 80:
- Port 80 is the port that the server 'listens to' or intends to receive from a Web client on a Web server or hypertext transfer protocol daemon, assuming that the default was taken when the server was configured or set up.
- A port can be specified on the NCSA server in the range of 0-65536.
- The server administrator however configures the server to recognize just one port number.
- The port number of a Web server is 80, by default.
Reason:
- Port 80 is a standard HTTP port.
- The default web port is 80. When the open some url in client without specifying a port, 80 is used by default.
- If a web server is operating on the same computer, then one can't open a server socket on an open port (port 80) because, it is already in use and it will generate an error.

- Write a C++ program that will count from 1 to 10 by 1. The default output should be 1, 2, 3, 4, 5, 6 , 7, 8, 9, 10 There should be only a newline after the last number. Each number except the last should be followed by a comma and a space. To make your program more functional, you should parse command line arguments and change behavior based on their values. Argument Parameter Action -f, --first yes, an integer Change place you start counting -l, --last yes, an integer Change place you end counting -s, --skip optional, an integer, 1 if not specified Change the amount you add to the counter each iteration -h, --help none Print a help message including these instructions. -j, --joke none Tell a number based joke. So, if your program is called counter counter -f 10 --last 4 --skip 2 should produce 10, 8, 6, 4 Please use the last supplied argument.
