problem with function calling

here is my code

Code:

---


#include <iostream.h>
#include <fstream.h>
#include <stdio.h>
#include <conio.h>
#include <string.h>

#define MAX 10
char choice;
char type;
int i;
//-----------------------------------
//base and derived classes
class books {
 public:
struct database {
    char title[256];
    char author[256];
        char isbn[11];
        char publishername[256];
        char cdrom[4];
        char yearofpub[5];
        char price[5];
  }np[MAX];  // end of struct
//..........................
  void find(void);
  void enter(int);
  void remove(void);
  void first(void);
  void list(void);
 
};
//------------------------------------



class store: public books{
        public:
        void save(void);
        void load(void);
};

    char name[12]="peter minns";
       
//------------------------------------
int main(int) {
int x=1;
  books bdata;
  store storage;
  do{
  storage.first();
 
  return(0);
  }while(x=1);
  };
 
//------------------------------------

void books::first(void) {
//do {
system("cls");

cout<<"***********************************************************\n";
cout<<"***********************************************************\n";

cout<<" S                        Show all books\n";
cout<<" Q                        Quit program\n";
choice=getchar();
choice=toupper(choice);

switch(choice) {

        case 'A': {
                cout<<"you selected 'Add'\n";
       
                enter(i);
               
                break;}

                break;}

                break;}         
               
       
        case 'C': {
                cout<<"you selected 'Clear'\n";
                break;}
               
        case 'S': {
                cout<<"you selected 'show all'\n";
                list();
                break;}
               


        case 'Q': {
                cout<<"you selected 'Quit'\n";
                break;}

       
};
//}while(choice!='Q','A');
};

                        cin>>(np[i].title);
                        cout<<"Enter the author: ";

                        cout<<"Year published: ";
                        cin>>(np[i].yearofpub);
                        cout<<"Enter price - exclude  sign: ";
                        cin>>(np[i].price);
                       
                        cout<<"\n\n\n information added to database\n\n\n";
                        system ("cls");
                        main(0);
};

void books::list(void) {
int i;
int ch;
for (i=0; i<2; i++) {
        cout<<"title "<<np[i].title<<endl;}
       

 
        main(0);
        //cout<<"name "<<np[i].name<<         
}

the problem is in the enter function. After the information has been entered the program calls main(int) again but then breaks from the program. Anyone know how i can stop this?

Code:

---

//---------------------------------------
//member functions
                void books::enter(int i) {
               
                        cout<<"Enter the book title: ";
                        cin>>(np[i].title);
                        cout<<"Enter the author: ";
                        cin>>(np[i].author);
                        cout<<"Enter the ISBN number: ";
                        cin>>(np[i].isbn);
                        cout<<"Enter the publisher name: ";
                        cin>>(np[i].publishername);
                        cout<<"Is there a CDROM included (yes or no): ";
                        cin>>(np[i].cdrom);
                        cout<<"Year published: ";
                        cin>>(np[i].yearofpub);
                        cout<<"Enter price - exclude  sign: ";
                        cin>>(np[i].price);
                       
                        cout<<"\n\n\n information added to database\n\n\n";
                        system ("cls");
                        main(0);
};

I want to be able to access the menu system again after every function.

Cheers

Andy :o

You don't call main(). When a subprogram finishes, it returns control to its caller up to main() and eventually main() returns to OS.

Oh i see. I didnt call it earlier but i still had the same problem so i will change that.

But i need main to call first() every time a sub program finishes. Can i do that with my loop?

Cheers for the help

Andy

You got some design issue, but for now...

Code:

---

int main()
{
    char choice;
    books bdata;
    store storage;
 
    do {
        storage.first(choice);
    } while(toupper(choice) != 'Q');
};
