/*
Corporate Sales Data

Write a program that uses a structure named CorpData to store the following
information on a company division:
	Division name (such as East, West, North, or South)
	First quarter sales
	Second quarter sales
	Third quarter sales
	Fourth quarter sales
	Total annual sales
	Average quarterly sales.
Include a constructor that allows the division name and four quarterly sales
amounts to be specified at the time a CorpData variable is created.
The program should create four variables of this structure, each representing one
of the following corporate divisions: East, West, North, and South. Each variable
should be passed in turn to a function that calculates and stores the total sales
and average quarterly sales for that division. Once this has been done for each
division, each variable should be passed in turn to a function that displays the
division name, total sales, and quarterly average.

Hello Leonardo797,

Neither piece of code will compile. Both are full of errors.

I do not know why you think that unicode characters («) or (») are what you need when just (<<) and (>>) are what is needed. This may look fancy in your code, but just causes errors.

Line 6 in each code is a comment when it should be defining your constant variables.

First you need to fix the errors to see if will compile successfully.

Hello Leonardo797,

After I fixed the errors I did make a change to the struct.

struct Info
{
    char name[NAME_SIZE]{};
    int age{};
    char addressl[ADDR_SIZE]{};
    char address2[ADDR_SIZE]{};
    char phone[PHONE_SIZE]{};
};

I initialized all the variables.

I also had to add "again". Used, but never defined. Needs to be defined before the do/while loop.

thanks, andy,

can you post the full code thx

Hello Leonardo797,

No. The code I have has nothing to do with the changes to the code that you made in your OP. Even the instructions appear to have changed.

Also you should not have changed the original post with this new code. Either close this topic and start another or post the new code in a reply.

It will take a little time to understand all the new changes.
