XII boards project HELP!!!

[djsingh6000]

Hi..
i wanted to make a project for my 12th boards and i chose the topic "Parking Lot Administration". I had started writing all the functions and everything.. but i needed it in BINARY FILE.. n i dont know how to do it..
MY ROUGH CODING IS GIVEN BELOW :

#include<iostream.h>
#include<stdio.h>
#include<math.h>
#include<string.h>
#include<stdlib.h>

class vehicle
{  char vehno[15];
   char typ;
   int time;
   int level;
   public:
   int parking_lot_no;
   void enter_details(int a)
   { int a;
     cout<<"enter the type of vehicle:"<<endl;
     gets(typ);
     cout<<"enter the vehicle no:"<<endl;
     gets(vehno);
     cout<<"enter the time of entering (in 24 hr clock):"<<endl;
     cin>>time;
     cout<<"enter the parking level:"<<endl;
     cin>>level;
     parking_lot_no=a;
     cout<<"parking lot no.:"<<a;
   }
   void show_details()
   { cout<<"type of vehicle:"<<typ<<endl;
     cout<<"vehicle no."<<vehno<<endl;
     cout<<"time of entering:"<<time<<endl;
     cout<<"parking level:"<<level<<endl;
     cout<<"parking lot no.:"<<prking_lot_no<<endl;

COULD Ne1 help m eout converting it to binary and modifying it a little bit so that it looks like a decent XIIth boards program..
plssssssss do sum1 help.. my carreer depends on this :(
PLSSSS HELP!!!
regards...

>>COULD Ne1 help m eout
Huh??? is that Chinese or Japanese you are writing. Please write English.

>>converting it to binary
converting what to binary? Your program? All you have to do is use a compiler and compile it. The compiler will create the *.exe file (well, technically its the linker that does that.).

> I had started writing all the functions and everything
There's a saying which reads "hours spent thinking about the design can save months of coding". This applies here.

A prime example being why all your 'A' to 'E' objects and functions all look the same. There should only be one of each, and a parameter.

OMG, did you even bother to compile the code like halfway through or anything? There are any number of copy/paste errors which should have been eliminated at the first instance, not replicated five times.

Your career can do without you if this is your approach to software development. We're not here to help you get a job you're incapable of, or keep a job you're incapable of performing. http://www.catb.org/~esr/faqs/smart-questions.html#writewell

Nonononono......
I've to make the program using BINARY FILES...... i need same functions and all.. but in BINARY FILES[file management concept in C++] and then ill have to compile the way u sed

[Ancient Dragon]

>>project for my 12th boards
we don't know what you mean by that.

>>program using BINARY FILES
Don't know exactly what you mean by that either. Do you want the vehicle data to be written to and read from a data file in binary format? You need to create an array (or c++ vector) of vehicle classes vector<vehicle> vehicleArray; then when done inputting the data write them all out to a file in their binary form

ofstream out("vehicles.dat", ios::binary);
vector<vehicle>::iterator it;
for(it = vehicleArray.begin(); it != vehicleArray.end(); it++)
{
    vehicle& v = *it;
    out.write(&v, sizeof(vehicle));
}

Reading the file on program startup is just as simple. Leave that up to you to write.

I thought it was some hardware module for a while, but it seems it's an Indian examination board, for what would appear to be 12th grade (in US terms).
It seems to be a useful step into getting to a university.

But the OP needs to fix all the systemic errors in their program before worrying about a minor detail as to whether the output file is text for binary.
