control problem

[Kingsley]

hi all,

I've done this code which has to book seats for a particular gala performance.

main()
{
int flag[100], num;

//num=number of seats booked at a time
//flag[i]=1 for seats that are booked
//flag[i]=0 for seats still available

//initially all 100 seats are available

for(int i=0;i<100;i++)
flag[i]=0;

printf("Enter the number of seats to be booked : ");
scanf("%d",&num);

int j=0;

while(!flag[j])
{
for(int k=0;k<num;k++)
flag[k]=1;
if (flag[k+num-j]==1)
break;
else
{
continue;
j++;
}

This should first scan the array for elements with flag[] = 0 and set flag[ ] =1 for the elements encountered then on upto the limit specified by 'num'. But it is not doing so...suggestions anyone?

take out the else block, and just put "++j;"

Read about continue, 'cause you're using it wrong.

Thanks for your reply, but it is still not getting there....

I was working on a menu-based program which takes user input till it is asked to exit - it reserves empty seats, cancels already booked seats and displays available seats as per user choice.

The availability and the cancellation parts can be done once the reservation one is.....

The class Performance

A class to describe the state of seats for an individual performance at a cinema. This class has the following methods:

available - Return true if there are n seats available for the performance otherwise return false.

book - Book n seats. The number of seats booked is returned, hence a result of 0 indicates failure.

cancel - Cancel the booking for seats already booked.

remaining - Return the number of seats not booked for this performance.

That seems to indicate you're to write a class, which is a feature of C++. This would be the C forum. At any rate, your above code makes no indication of a class. If you're to use C++ classes (as your previous post seems to imply), the least you could start with is a class with those members, even if they're empty.
