Two Mysteries or Problems

**zenghoong** · 10-12-2009

I'm creating an airline reservation for my assignment and the menu is working fine. The two problems I'm currently facing are:

1. After you choose LK and choose Business, the program displays the FULL message even before any tickets are booked. If you try with "KL Business", "KL"Economy" and "LK Economy", it will start asking for your designation. I've looked through the codes and are quite sure they are similar. Please help me find what is wrong.

2. When you choose either "KL Business", "KL"Economy" and "LK Economy", they will ask you for your designation. But once I entered a value, errors keep popping out! Help.

Here's my code:

*code removed*

one error which is easily everyone can get is tyou are having two global variables with same name
customer

Code:

int customer[2][4][5] = {0};

And

Code:

struct custinfo
{
	char desg;
	char fname;
	char lname;
	char icnum;
	int  seat;
}customer[2][4][5];

ur code was compiling on ur machine ??

**zenghoong** · 10-12-2009

It was. except it will display an error when it reaches the purchasing page.

**zenghoong** · 10-12-2009

And, i tried removing this line

Code:

int customer[2][4][5] = {0};

but nothing seems to have changed

what the hell u are coding man its big mistake dude

see what the hell u r doin

ur structure is

Code:

struct custinfo
{
  char desg;
  char fname;
  char lname;
  char icnum;
  int  seat;
}customers[2][4][5];

and while inserting the data u r putting string

man char is a single character it can hold like 'a' 'b' etc

char* or char[] is a string of character like "rocky marrone" etc

Code:

int printticket(void)
{
  if (seat[a][b][c] == 0)
    {
      printf ("\nEnter Designation [Mr/Ms]: ");
      scanf ("%s", &customers[a][b][c].desg);
      printf ("\nEnter First name: ");
      scanf ("%s", &customers[a][b][c].fname);
      printf ("\nEnter Last name: ");
      scanf ("%s", &customers[a][b][c].lname);
      printf ("\nEnter IC number: ");
      scanf ("%s", &customers[a][b][c].icnum);

      seat[a][b][c] = 1;
      seatcount = seatcount+1;

      customers[a][b][c].seat = seatcount;

      printf ("\nName: %s. %s %s", customers[a][b][c].desg, customers[a][b][c].fname, customers[a][b][c].lname);
      printf ("\nIC Number: %s", customers[a][b][c].icnum);
      printf ("\nSeat Number: %s", customers[a][b][c].seat);

    }
  return seatcount;
}

change ur structure like

Code:

struct custinfo
{
  char* desg;
  char* fname;
  char* lname;
  char* icnum;
  int  seat;
}customers[2][4][5];

**zenghoong** · 10-13-2009

do you suggest I use short instead of char?

**RockyMarrone** · 10-13-2009

And one more silly mistake

Code:

int printticket(void)
{
  if (seat[a][b][c] == 0)
    {
      printf ("\nEnter Designation [Mr/Ms]: ");
      scanf ("%s", &customers[a][b][c].desg);
      printf ("\nEnter First name: ");
      scanf ("%s", &customers[a][b][c].fname);
      printf ("\nEnter Last name: ");
      scanf ("%s", &customers[a][b][c].lname);
      printf ("\nEnter IC number: ");
      scanf ("%s", &customers[a][b][c].icnum);

      seat[a][b][c] = 1;
      seatcount = seatcount+1;

      customers[a][b][c].seat = seatcount;

      printf ("\nName: %s. %s %s", customers[a][b][c].desg, customers[a][b][c].fname, customers[a][b][c].lname);
      printf ("\nIC Number: %s", customers[a][b][c].icnum);
      printf ("\nSeat Number: %s", customers[a][b][c].seat);

    }
  return seatcount;
}

In the above function customers[a][b][c].seat is of type int and you are using %s for it i think you should use %d otherwise it will give seg fault

Code:

int printticket(void)
{
  if (seat[a][b][c] == 0)
    {
      printf ("\nEnter Designation [Mr/Ms]: ");
      scanf ("%s", &customers[a][b][c].desg);
      printf ("\nEnter First name: ");
      scanf ("%s", &customers[a][b][c].fname);
      printf ("\nEnter Last name: ");
      scanf ("%s", &customers[a][b][c].lname);
      printf ("\nEnter IC number: ");
      scanf ("%s", &customers[a][b][c].icnum);

      seat[a][b][c] = 1;
      seatcount = seatcount+1;

      customers[a][b][c].seat = seatcount;

      printf ("\nName: %s. %s %s", customers[a][b][c].desg, customers[a][b][c].fname, customers[a][b][c].lname);
      printf ("\nIC Number: %s", customers[a][b][c].icnum);
      printf ("\nSeat Number: %d", customers[a][b][c].seat);

    }
  return seatcount;
}

After adding the * to the structure like this:

Code:

struct custinfo
{
  char* desg;
  char* fname;
  char* lname;
  char* icnum;
  int  seat;
}customers[2][4][5];

The program won't run. It says

Code:

**zenghoong** · 10-13-2009

Its funny because after I added the * to everything, like this:

*code removed*

It says

Code:

1>c:\users\user\desktop\pspd\ppspd6\ppspd6\pspd66.c(225) : error C2059: syntax error : '*'

Try removing a lot more than that. Any functions or other parts that aren't necessary to demonstrate the problem(s) should be removed before posting the code. By posting too much code you put most people off from bothering to try and help.
You also lose some opportunity to possibly solve the problem on your own and gain the valueable experience from doing so.

**RockyMarrone** · 10-13-2009

k just do one thing then

change ur structure like this it will work

Code:

struct custinfo
{
  char desg[4];
  char fname[20];
  char lname[20];
  char icnum[20];
  int  seat;
}customers[2][4][5];

**zenghoong** · 10-13-2009

Done. But now, it says:

Code:

1>c:\users\user\desktop\pspd\ppspd6\ppspd6\pspd66.c(226) : error C2224: left of '.desg' must have struct/union type
1>c:\users\user\desktop\pspd\ppspd6\ppspd6\pspd66.c(228) : error C2224: left of '.fname' must have struct/union type
1>c:\users\user\desktop\pspd\ppspd6\ppspd6\pspd66.c(230) : error C2224: left of '.lname' must have struct/union type
1>c:\users\user\desktop\pspd\ppspd6\ppspd6\pspd66.c(232) : error C2224: left of '.icnum' must have struct/union type
1>c:\users\user\desktop\pspd\ppspd6\ppspd6\pspd66.c(237) : error C2224: left of '.seat' must have struct/union type

1>c:\users\user\desktop\pspd\ppspd6\ppspd6\pspd66.c(240) : error C2224: left of '.icnum' must have struct/union type
1>c:\users\user\desktop\pspd\ppspd6\ppspd6\pspd66.c(241) : error C2224: left of '.seat' must have struct/union type

Don't know why it isn't working.

**RockyMarrone** · 10-13-2009

look at the structure more closley i m having name

Code:

struct custinfo
{
  char desg[4];
  char fname[20];
  char lname[20];
  char icnum[20];
  int  seat;
}customers[2][4][5];

customers i think u must be using only customer

**zenghoong** · 10-13-2009

i've changed it all to customer now. But still no luck.
