member function not getting called? inside switch case

[struntz]

Hello everyone!!
I'm trying to create an inventory program here, and i dont' know C, but I have been trying to learn C++. I coudn't seem to find any C++ libs that worked as well as the <stdio.h> lib, so i used that inside this project...well when i go to add a record, it seems as if the function doesn't even get called! If u compile this code, Hit 1, and then hit 1 again to create the new DB, and then hit 2, to add a record adn see for urself, i put a statement to see if teh add record function even got called but it looks as if it isn'te ven getting called! I may have made an error in the C code becuase i dont' know C, i just looked at the C syntax of the function and tried my best heh, but here is some notes if u don't understand FILE pointers...
fp is the file pointer, and this shows where u want it to point too... FILE*fp = openf("test","w"); the "w" will create a file called test, and if there is another file called test, it will delete the old file! so for the add record i tried, fp=openf("test","a") which is supppose to let me add thigns to the file, without erasing the orginal contents...



here is the code

//animals.h
//Age, type, health, sex, characteristics, date found, location, other
#include <iostream.h>
#include <string.h>
#include <stdio.h>
#include <stdlib.h>


class Animal
{
public:
	int menu();
	void createDB();
	void addRecord();
	void delRecord() { cout<<"delete record function\n"; }   //working on
	void search() { cout <<"search record function\n"; }	//working on 
	void quit() { exit(1);}
	
private:
	int age;
	char type[30];
	char health[20];
	char sex;
	char discript[100];			//not used yet
	char location[50];			//not used yet
	char other[100];			//not used yet
	FILE* fp;                 //file pointer
};



void Animal::createDB()
{	
	fp = fopen("inventory","w");          //writing privallages only
	cout<<"Database Created!\n";
	fclose(fp);
}


void Animal::addRecord()
{
	cout<<"add record called\n";
	fp= fopen("inventory","a");
	cout<<"/nEnter Data\n";
	cout<<"age   type   health  sex\n";
	
	fscanf(stdin,"%d %s %s %c", &age,&type,&health,&sex);		//get input
	fprintf(fp,"%d %s %s %c",age,type,health,sex);				//print to file
	
	fclose(fp);				//closing file
}

int Animal::menu()
{
	int choice;
	cout<<".::--------------------Animal Menu---------------------::.\n";
	cout<<"(1) Create a Database\n";
	cout<<"(2) Add a new record\n";
	cout<<"(3) Delete a record\n";
	cout<<"(4) Search\n";
	cout<<"(5) Return to Main Menu\n";
	cout<<".::----------------------------------------------------::.\n";
	cin >> choice;
	switch(choice)
	{
	case 1: createDB();
		break;
	case 2: addRecord();
		break;
	case 3: delRecord();
		break;
	case 4: search();
		break;
	case 5: return 0;
		break;
	default: cout <<"Error.  Please enter a choice, 1-4\n";
	}
	menu();
	return 0;
}






class Date
{
public:
	int mm;
	int dd;
	int yy;
};


void intro()
{
	cout<<"**********************************************************\n";
	cout<<"|                  Welcome To Project FluX               |       \n";
	cout<<"**********************************************************\n";
	cout<<"\n\n";
}



//*******Main Menu*****
void mainMenu()
{
	Animal animal;
	int choice;
	cout<<".::---------------------Main Menu----------------------::.\n";
	cout<<"(1) Create a Database\n";
	cout<<"(2) Add a new record\n";
	cout<<"(3) Delete a record\n";
	cout<<"(4) Search\n";
	cout<<"(5) Quit\n";
	cout<<".::----------------------------------------------------::.\n";
	cin >> choice;
	switch(choice)
	{
	case 1: animal.menu();
			mainMenu();
		break;
	case 2: animal.menu();
			mainMenu();
		break;
	case 3: animal.menu();
			mainMenu();
		break;
	case 4: animal.menu();
			mainMenu();
		break;
	case 5: cout<<"thank you for using my program\n";
		exit(1);
		break;
	default: cout <<"Error.  Please enter a choice, 1-4\n";
	}
	mainMenu();
}

here is the main.cpp

#include "animals.h"

//prototypes
void intro();
void mainMenu();


int main()
{
	intro();
	mainMenu();

return 0;
}

thanks for listneing

Ahh i finally fixed it , i had to rewrite the whole functions, and I gave up using C and C++, so i just used C++'s <fstream> it seems alot more easier to read and unsterstand

and i just used

ofstream outfile("inventory.txt",ios::ate); 

to append to the file
