Quote:


Family Outfit Shop decided to create a computerized system to maintain the shop inventory. The shop sells variety of garments and the garments are categorized to a particular group. Each category is given a code and the explanation for each code is given bellow.


CODE | EXPLANATION
A | baby wear
B | children wear
C | ladies wear
D | menswear

You as a programmer are required to write a program which contains a menu as bellow:

Family Outfit Shop
MAIN MENU
1)Add a record
2)Display sales report for a category
3)Display sales report for all category
4)Exit


Guideline
The program should give the user an option to choose any sub menu and it would only stop when the user choose the Exit sub menu.

1)Add a record
This sub menu will add a sales record for a particular garment into a file name jualan.dat. Each record consists of three fields which are item number, item code and price. The user may add more than one record at a time. You can use a sentinel value to control the loop. Assumed that file jualan.dat already exists. Example of file jualan.dat is shown as bellow:
A101= A =10.00
B101= B = 12.00
A102 =A= 5.00
B105= B = 17.00
C103 =C= 40.00
D101 =D = 15.00
B104 =B =20.00


2)Display sales report for a category
In this sub menu the sales report of a particular category will be displayed. The category shall be chosen by the user.

SALES REPORT FOR BABY WEAR
Item Number | Price
A101 | 10.00
A102 | 5.00
Total Sales | 15.00


3)Display sales report for all category
In this sub menu the sales report for all the categories will be displayed.

SALES REPORT FOR ALL CATEGORIES
Category Sales
Baby wear 15.00
Children wear 49.00
Ladies wear 40.00
Menswear 15.00
Total Sales 119.00


4)Exit
End of program.

Re: To call file
 
Code:

std::string explanation; // this upper coding
        char explanation; //after entering void to display

You need to decide if explanation should be defined as std::string or char. char only stores one character (you need char explanation[20] or some other int if you want to use an array of char), so given that you want to use the
Code:

    explanation='BABY WEAR';
syntax I suspect it should be defined as the first. Your error is probably something along the lines of "explanation: already defined", which you get because you've defined it twice.

In future, if you get errors, tell us what they are. It's not always this easy to guess what those errors might be.
