Enqueue Help

[JackDurden]

Trying to make a circular queue, but its not working right. Enqueue is just adding things to the end, every time.

my output is:
Numbers in Queue: 1 2 3
Numbers in Queue: 2 3
Numbers in Queue: 2 3 6

it should be:
Numbers in Queue: 1 2 3
Numbers in Queue: 2 3
Numbers in Queue: 6 2 3

any suggestions?

                queue.Enqueue(3);

That's the way your queue is supposed to work -- its capacity is 5, not 3.

My main suggestions have to do with coding style. Don't have the return type be object if you only return a bool; return void if you're going to return the same bool every time; don't name separate functions Empty and empty because that's retarded; use capital names for all your functions because that's C# style; use lowercase names for private variables because that's C# style; whatever naming scheme you use, be consistent because that's convenient; in functions, avoid declaring variables without initializing them if you have no reason to do so, it just makes the code take more brain capacity to read that way; don't write x++; return (x); , just write return x + 1; ; don't write tail == 5 , write tail == Qlist.Length , because your code is more resilient that way; name your function "IsEmpty" instead of "Empty" because that's more clear, and rename "empty" to "Clear" because that's more Clear; have your function "empty" make it so that every element of qList is null, because that's consistent with the way your Dequeue function behaves; don't assign to variables and then never use them, the way you do with toDelete.
