The array str, because it doesn’t have an explicit size, is sized to exactly store what it is initialized with. And because an empty string only contains 1 character, namely a terminating null byte, your array is 1 element in size. This means str isn’t large enough to hold any string that’s not an empty … Read more
The i < 0 and i == 1 lines do not use the dictionary at all. For those early terms, the dictionary lookup would be slower than the calculation anyway. The if (memo.ContainsKey(i)) { return memo[i]; } line also does not set anything new in the dictionary. It reads from the dictionary, but does not … Read more
you are getting bigger numbers because on this line for(int i=0;i<n;i++){ cin>>arr[n]; } You are changing the value on arr[n] (that doesn’t exist because you array goes from 0 to n-1). Basically you are not changing any value inside the array so its using trash values that were stored on the memory. The fix to … Read more
As you said, it is little bit complex but not impossible. With small thought you might get this easily. I’ve implemented code but to give your brain some work I’m not posting the code but giving you pseudo code below. I thought of following way. First you need to have a duration through which you … Read more
I’m going to take a crack at it here and assume that with the info you’ve given you need a class structure like this: class Book { [XmlAttribute(“bookAttribute”)] public string bookAttribute = “”; [XmlElement(“Shelf”)] List<Shelf> Shelves = new List<Shelf>(); } class Shelf { } Then when you create the programmatic relationship between a book and … Read more
Keep a state in a boolean after the button is pressed once and then check if the button is pressed again within the next two seconds or so. If it is pressed again, perform whatever action you like. 2 solved Detecting Double Clicks not only for the mouse but for every key [closed]
As mentioned by πάνταῥεῖ in a comment, it seems that you’ve a few misconceptions regarding scope of variables, about parameters and about return values. Let’s see if we can’t dispel some of those. First of all, lets talk about scope. When we declare a variable inside a block delimited with { and }, the variable … Read more
Let’s construct our number that doesn’t have three consecutive ones from left to right. It necessarily starts with at most two 1s, so it starts with either no 1s, a single 1, or two 1s. In other words, our number starts with either 0, 10 or 110. In all of these cases, the only restriction … Read more
this.gridViewCastles.SetRowCellValue(rowHandle, column, (object) (bool) (flag2 ? 1 : 0)); What are you trying to do? Flag2 is a boolean. The ?: operator allows you to test a boolean condition to select one of two possible vaules, in your case, 0 and 1. In your code, you try to cast 0/1 to boolean. What is the … Read more
Yes you can, why did you think you can’t? But if the value is 0 you can skip the initialization since static variables are automatically initialized to 0. Also, as @M.M commented here it’s mandatory that the value is a constant, you can’t assign the result of malloc() for instance. There is no potential problem, … Read more
Your buffer is likely not being flushed. Try this: while(1){ //… fout.flush(); } 2 solved Why text file created is blank?
Beware that this code, as is, contains errors: bad cast, undefined behavior and platform dependent results… This is pointer arithmetic. w initially points to the content at the address of the first element of t (this is what w = (unsigned short *)&t means). Then, hereafter, you access this memory as containing successives shorts. At … Read more
Use BINARY or VARBINARY to store binary data. string query = “INSERT INTO dbo.MyTable(Content) VALUES(@Content)”; using(SqlConnection connection = new SqlConnection(/*yout connection string here*/)) using(SqlCommand command = new SqlCommand(query, connection)) { connection.Open(); SqlParameter param = command.Parameters.Add(“@Content”, SqlDbType.VarBinary); param.Value = YourByteArrayVariableHere; command.ExecuteNonQuery(); } You could retrieve it by using a SqlDataReader to get data and than cast … Read more
If I understand correctly: private string FunctionWithTwoParameters(string name=””, int count=0) { if (count > 0) { for (int i = 0; i < count; i++) { name += name; } } return name; } Such parameters of the method (string name=””, int count=0) means that you can call the method with or without parameters A … Read more
