***The code is provided below***

When trying to compile the code below, I'm receiving three errors. Can I get some assistance on correcting the issues?

I removed the code because I thought I corrected my problem. I used #define to get rid of the CRT errors, and included an int at main(). The code compiles but still does not run properly. When entering the insertion prompt for the call details, after entering the phone number, the program just continuously runs, instead of prompting next for the date, then time, & language. After the call insertion is complete, the program is suppose to go to Idol state and then route the call to an available agent at the prompt. Program is also suppose to display various statuses such as recently routed calls and stored calls.

Can I get some assistance on correcting the issues so the program runs properly? Also, with cleaner code without using #define?
