I need help in coding for turbo c++ in my assignment.

Hi Klement Chia,

I wondering that if u still have the complete coding for the assignment that you have done on the car renewal system with turbo C++.
Would you kindly email to it to me? Thanks n regards..

this is an actually a sample code given: but I have no idea how its going to be implemented into screen 4.


main()
{
    char date1[10], date2[10], mth1[5], mth2[5];
    char months[][5] = {"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"};
    int k, m;

    printf("Enter first date:  ");
    gets(date1);

    printf("Enter second date: ");
    gets(date2);

    mth1[0] = date1[0];
    mth1[1] = date1[1];
    mth1[2] = date1[2];
    mth1[3] = '\0';

    for (k=0;k<12;k++)
    if(strcmp(mth1, months[k]) ==0)
    break;

    mth2[0] = date2[0];
    mth2[1] = date2[1];
    mth2[2] = date2[2];
    mth2[3] = '\0';

    for (m=0;m<12;m++)
    if(strcmp(mth2, months[m]) ==0)
    break;

    if(k < m )
      printf("date 1 is less than date 2");

      else if(k == m)
      printf("both date are equal");

      else
      printf("date1 is greater than date 2");
}

Well its in the zip file..............

its using turbo C++.

Problem:

An established car rental firm in town offers a wide range of vehicles for rent to its customers. As the size of its fleet of vehicles got larger through the years the manager would like a software system  that could inform him which vehicles need their road tax renewed for a particular month. Design and develop a software system using C++ that could help solve this problem.

 

Screen 1:

This screen displays the main menu which consists of ADD VEHICLE, VEHICLE ENQUIRY, ROAD TAX RENEWAL REPORT, INTIALISE DATABASE and EXIT. You are required to incorporate any necessary validation checks and to design your own error messages.

Screen2:

This screen, ADD VEHICLE, with the field shown below, allows a new vechicle record to be created. The vechicle number which is an integer starting with 1 is to be determined by the operator. Put vehicle number 1 details into record 1; vehicle number 2 details into record 2 and so on. If the operator enters a vehicle number that already exists then display a warning message "Record exists…..overrite(y/n)". A random file called VECHICLE.DB is to be created.

The following checks should be made:

1.       Vehicle number            : integer.

2.       Registration number      :AAA9999 (eg. BA123)

3.       Make                          :alphabets only (e.g. Ford)

4.       Model                        :alphabets only(e.g. Model T)

5.       Engine Type                : D or P (diesel or Petrol)

6.       Engine Capacity(cc)      : 9999 (e.g. 2900)

7.       Road tax expiry date      : mmmm yyyy(e.g. May 1911)

Screen3:

This screen displays vechicle details, one vehicle record per screen. Display all details mentioned in screen 2 above. In addition, calculate and display (round up to whole number) the road tax amount ($2.25 per 100 cc).

Screen 4:

This is the ROAD TAX RENEWAL REPORT Module. This module needs to be run only once a  month (usually mid-month) to print a report (on the screen) which shows those vehicles in which the road tax is expiring for that month. This is done by comparing the road tax expiry date with the system date. Design Your own report format.

The code I had done except screen 4 that I really need help:

main Menu:
main()

{

   char val_choice;

   char show_menu();

 

   val_choice=show_menu();

 

return 0;

}

 

char show_menu()

{

   char choice='0';

   while(choice >'5' || choice <'1')

   {

    clrscr();

 

    gotoxy(30,4);

    cputs("========================================");

    gotoxy(30,5);

    cputs("Vehicle Tax");

    gotoxy(30,6);

    cputs("========================================");

    gotoxy(30,7);

    cputs("1. Add Vehicle");

    gotoxy(30,8);

    cputs("2. Vehicle Enquiry");

    gotoxy(30,9);

    cputs("3. Road Tax Renewal Report");

    gotoxy(30,10);

    cputs("4. Initialise Database");

    gotoxy(30,11);

    cputs("5. Exit");

    gotoxy(30,13);

    cputs("Enter choice:  ");

    choice=getchar();

 

    if(choice>'5' || choice <'1')

     {

      gotoxy(30,16);

      cputs("Invalid Choice. Please re-enter");

      }

      else

       return(choice);

      }

      return 0;

}
