help me urgent

[dky8810]

question:
The airline company, KL AIRLINE, has engaged your teanm to develop a new Airline Ticket Reservation System....airplane wiyh the occupancy of "20 passengers".

!.display the KL "Airline Reservation Menu" for the user to select from 2 main options which are to do "Booking" and "display seat layout & occupancy".thr is one last option -to "exit" from the system after displaying an appropriate farewell message.

2.Booking
-ask user for yhe number of seat required
-Generete the Booking ID(if enough seats are available)
-for each seat required,
*ask for the passenger name,
*assign the booking ID to the seat, and
*display the ticket in following format:
-------------------------------------------------------------------------------------
| --KL airline booking tikcket---- |
| booking ID:100 Flight No.:AK65 |
| Passenger:XXXXXXXXX Date :25-12-2008 |
| Time :23:45 |
| Gate :G9 |
| seat No :3B |
---------------------------------------------------------------------------------------

note:-( Flight No,Date,Time,Gate )will be initizalized either during compile-time or run time.the details are to be stored in a "Struture variable"
-hv all the necessary "validation" in place, including useful messages, "not enough seat available"
- must use a Two Dimensional Array to store the seat information(the booking ID or a Zero value).

3.display seat layout & Occupancy
sample:
A B C D E
|--------------------------------------------|
1 |101 | 101 | 101 |102 | 103 |
|-------------------------------------------|
2 |103 |104 |104 |104 |0 |
|-------------------------------------------|
| Aisle |
|-------------------------------------------|
3 | 0 | 0 | 0 | 0 | 0 |
|-------------------------------------------|
4 | 0 | 0 | 0 | 0 |0 |
|-------------------------------------------|

OK, now, what questions do you have to move forward? I notice that you have nothing in your display function, and your menu only lets you pick once.

if(cust[sizeR][sizeC] != 0)
the problem in this line show by my compile is binary '!=':'customer'does not define this operate or a conversion to a type acceptable to the predefined operator).
cust[sizeR][sizeC]is array of structure.
what code i need to use for know how many array element is empty ??
line 60-70

[dky8810]

i hv change the code :

void Booking(void)
{
int ID[4][5]={
{0,0,0,0,0},
{0,0,0,0,0},
{0,0,0,0,0},
{0,0,0,0,0}
};


customer cust[sizeR][sizeC];
int i;
int row;
int col;
int flag=0;
printf("How many seat are you required:\n");
scanf("%d",&i);
for(row=0;row<sizeR;row++){
for(col=0;col<sizeC;col++){
if(0==ID[4][5]){
flag=1;
break;
}
}

if(flag==0)
printf("Please enter your name\n",cust[sizeR][sizeC].name);
else
printf("Not enough seats available!The flight is fully booked!");
}
}

in this part it keep looping how to stop it??
if(flag==0)
printf("Please enter your name\n",cust[sizeR][sizeC].name);

1) please use code tags when posting code.
2) you cannot compare a struct with 0. You have to compare an item in the struct with 0.
3) the break only breaks you out of the inner for loop, not the outer for loop.

int ID[4][5]={
{0,0,0,0,0},
{0,0,0,0,0},
{0,0,0,0,0},
{0,0,0,0,0}
};

this is "array" not struct ,so i dont understand why saying that compere a struct with 0?
the break .....can give an exemple?

int ID[4][5]={
{0,0,0,0,0},
{0,0,0,0,0},
{0,0,0,0,0},
{0,0,0,0,0}
};

help help!!
i no ideal for next part

question:
now is this part make me blur:what i need to write in <if>the code that can let me check still got how many empty place in my cust array??
Code:

for(row=0;row<sizeR;row++){
for(col=0;col<sizeC;col++){
if(0==ID[row][col]){
	for(j=0;j<i;j++){
		printf("Enter your name");
		scanf("%[\n]c",cust[sizeR][sizeC].name);

}
else{
printf("Not enough seats available!The flight is fully booked!");

can?

[WingedPanther]

1) You are never updating array ID to non-zero values.
2) It seems like you need to sit down and create a flowchart/pseudocode of your logic. I don't have a clear sense that you have thought out what you want to do. Instead, you seem to be changing things and getting things worse, rather than better.

[dky8810]

void Booking(void)
{
 strcpy(cust[sizeR][sizeC].flightNo,"AK65");
 strcpy(cust[sizeR][sizeC].date,"25-12-2008");

 {0,0,0,0,0},
 {0,0,0,0,0}

 printf("How many seat are you required:\n");
 scanf("%d",&i);
 int available_seats = 0;
  for(row=0; row<sizeR; row++){
   for(col=0; col<sizeC; col++){
    if(cust[sizeR][sizeC].id == 0){
     available_seats++;
    }
   }
  }
  if(available_seats >= i){
   for(j=0;j<i;j++){
    printf("\t\t\t--- KL Airline Booking Ticket ---\n");
    cust[sizeR][sizeC].id=id;
    id++;
    printf("\t\t\tBooking ID\t:%d",&cust[sizeR][sizeC].id);

     Booking();
    }
    else
    {
     system("cls");
     menu();
    }*/
   }
  }



      
  else{
   printf("Not enough seats available!");
  }

why it keep looping?which line i wrong????
