member function not getting called? inside switch case
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
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
Code:
#include "animals.h"
//prototypes
void intro();
void mainMenu();
int main()
{
intro();
mainMenu();
return 0;
}
thanks for listneing
:D
