Menu, how to put calculation in there

so, this is my coding.

Code:

#include<iostream.h>
#include<fstream.h>
#include<stdlib.h>
#include<iomanip.h>
    using std::cout;
    using std::cin;
    using std::endl;
    
    struct menu
    typedef struct menu RECORD;
    void addRecord(RECORD input[], int arraycounter);
    void printRecord( input[]);    
    void printAllRecord( input[]);
    
int main()
{
    fstream submit;
    submit.open("D:jualan.dat",ios::out);
    
    {
    int menuEnter;
    int arraycounter=0;
    
    do
    {
    cout<<"\tFamily Outfit Shop"<<endl;
    cout<<"\t    MAIN MENU"<<endl;
    cout<<"\t-------------------"<<endl;
    cout<<" 1 = Add a record\n";
    cout<<" 2 = Displays sales report for a category\n";
    cout<<" 3 = Displays sales report for all category\n";
    cout<<" 4 = Exit";
    cout<<"\nEnter Menu Number : ";
    cin>> menuEnter;
     
    if(menuEnter == 1 )
    addRecord;
    else if (menuEnter == 2 )
    printRecord;
    else if (menuEnter == 3)
    printAllRecord;
    } while (menuEnter!=4);
    return 0;
    }
     
    void addRecord(RECORD input[], int arraycounter);
    {
    char codeCate; // code category
    char codeNumbCate;  // code number category

    cout<<"Enter code category : \n";
    cin>>input[arraycounter].codeCate;
    cout<<"Enter code number of category : \n";
    cin>>input[arraycounter].codeNumbCate;
    arraycounter++;
    }
     
    void printRecord(RECORD input[]);
    {
     
    cout<<"SALES REPORT FOR "<<explanation<<endl;
    cout<<"\nItem Number\t\tPrice" << endl;
    cout<<"------------------------------"<<endl;
    cout<<codeCate<<"\t\t"<<price<<endl;
    cout<<"------------------------------"<<endl;
    cout<<"Total Sales\t\t"<<totalSales<<endl;
    cout<<endl;
    }

    void printAllRecord(RECORD input[]);
    {
    cout<<"SALES REPORT FOR ALL CATEGORIES"<<endl;
    cout<<"\nCategory\t\tSales" << endl;
    cout<<"------------------------------"<<endl;
    cout<<explation<<"\t\t"<<price<<endl;
    cout<<"------------------------------"<<endl;
    cout<<"Total Sales\t\t"<<totalSales<<endl;
    cout<<endl;
    }
}

error? yes, it is, bcoz i still did not finish it...
still, i'm running doing this coding and keep doing it, but i need help.
i keep doing mine, still someone must help me.
i will post update for my new coding...

there is the question. sorry bcoz it is long.

so, how / where to put claculation in there?
i means, in record or print...
i try....
and also, how to display multiple of item number?

 

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

 

seriously anybody?

 

Your "struct menu" statement is incomplete. The compiler won't be able to get past that until you complete the statement.

Let me tell you how professionals write code. They write a FEW lines at a time - 4-5 is not unknown - then compile it and look for errors, fix them, then run the code and make sure it works. Then they write a few more lines - again maybe 4-5, maybe more, maybe less, then compile and run. It looks like you're trying to write the whole program before compiling it.

Get the code you have written so far working, THEN we'll look at how to add calculations. Post your reply here; do not keep creating new threads.
