Question
For our week 2 assignment create a C++ program using Visual Studio where you design a “PhoneCall” class that holds a phone number to which a call is placed, the length of the call in minutes, and the rate charged per minute. Overload the extraction and insertion operators for the class; these are shown in the Chapter 9 ppt as ostream and istream, i.e. cout and cin. In this program, overload the == operator to compare two PhoneCall objects. Consider one PhoneCall object to be equal to another if both calls are placed to the same phone number. Also, create a main() function that allows you to enter ten PhoneCall objects into an array. If a PhoneCall has already been placed to a number, do not allow a second PhoneCall to the same number.
Compile this application using Visual Studio and run it to make sure it is error free.
Please copy and paste ALL (use Control-A, control-C, control-V) of your C++ code to a Word file. I will copy, paste, read and test your code for grading.
This is for C++
