Programs like action strings code#

Below is the syntax for its implementation. Take the assignSeat() in Seats.Write a loop that reads strings from standard input I have implemented that but unfortunately it doesn't help me, let me explain why. I can see you both suggested to use a sentinel value of -1. Return true // let the user know assigning a seat succeededДЄnd I can't return another one.how do I return 2 values? is it possible? If I manage to return the class chosen by the user then it is quite easy to call the function again on that particular class and check if there is any seat available

Programs like action strings code#

Let's have a quick look at the code first: //ex 7.19 p 333 deitel and deitel

So far so good, but I have now a few questions (yes I know, surprise surprise!). Right ok, I have changed the program quite a lot and took the approach that stultuske has suggested. If you want an instruction to happen only under some circumstances, that is what if statements are for, as in: 'if the seat is available, assign the seat.'

If you say check to see if a thing is a good idea, then do the thing, then the thing will always get done because you said so, even when the check turns out that it was a bad idea, because you only said to do the check, not to use the result of the check. No one is going to fudge your instructions to make it work. In programming you have to say exactly what you mean. It's in the instructions as the next step after checking.' I just told you it's already been assigned to someone else.'

'Check the seat hasn't been assigned yet.' Imagine that instead of a computer your pseudocode is being executed by an employee at the ticket desk of an airline as the code is read aloud by a supervisor. You don't only do a step if it seems like a good idea that's not how programming works. In code or pseudocode, you proceed one step at a time doing each step. You were assigning seats without checking way back in the first post of this thread, and by now you've upgraded to checking then ignoring the results of the check and assigning anyway. You're not supposed to assign the seat unless it is available. isn't it funny? That's what you're doing right now. And then, on the 3rd day, you get a all-in-one method-calculator with a huge bunch of incoming parameters, indicating the operation, additional params etc. A few days you hear nothing from developer. Haven't anyone faced such situation, when you ask 'code me a method, which sum's a two numbers'. And you should code them maximally close to that wording. Of course, in real-world programming, you should think of possible ways, but they're as usual must beДЇully documented as your assignment. C'mon guys, hwo's ready to build up a commercial booking application using only 1-dimentional arrays with no classes and enums? ) moreover, there're still a pretty big bunch of interesting topics, that isn't covered yet (including enums, complete information of class usages etc.). Same sits booking, but we have extra class and a few 'fuselages'. It can be way different from '11-seats plane'.

So, if you have a task to make a 1-dimentional array with a sits 1-5 for an economy class and 6-10 for business, there's no need to try to guess all possible usages for your code. Programming is all about complexity management.
