Question

Write program using either C#, C++, or Java. These are all the specifications given. Its for a quality course so the main part will be when I do testing. I just need the code for the program. Thanks!

Telephone Switching Simulation This project simulates basic telephone functions. You will not be hooked up to real phones, but instead will input commands from the keyboard, and display results. Your system will make phone calls, as well as perform three-way conferences and transfers. The requirements are as follows 1. At startup, the program will read a file containing phone numbers and names. There may be up to 20 such pairs, one per line. phone number may begin with 0 Names are a single word (no first name, last name 2. The phone numbers are 5 digits long, all numbers. A 3. The names are a single name field up to 12 characters. let's keep it simple.) Names are all alphabetic: A-Za-z. 4. Commands are: a phone call phone b. phone offhook c. phone onhook d. phone transfer phone e phone conference phone s. In each command, the phone is either the phone number or the name 6. Possible responses are as follows. See later requirements for the conditions for each response a phone hears dialtone b. phone hears ringback c. phone hears ringing d. phone hears busy e.phone hears denial t phone hears silence g. phone and phone are talking h. phone and phone and phone are talking 7. Normal call
