[ad_1] In first example you are reading it as ’20’ and ‘3’ -> So not equal. In second exmple you are reading it as ’20’ and ‘ 3’-> note space. Its not 2 vs 3. It is 20 vs 3. %d will read whole string. You may want to check with %1d Return from strcmp … Read more
[ad_1] I’m assuming that you want something like this printed out? Is that right? You just do “%d” in the spot that you want to display your integer and outside the quotes you put a comma and the integer you wanted to print. // These are the calculations below in which I need to get … Read more
[ad_1] Directly apply the definition of Fibonacci series: To get a 1:1 translation: int f(int N) { int fn = N; // Edit: init fn with N int fn_1 = 1; int fn_2 = 0; while (N >= 2) { fn = fn_1 + fn_2; fn_2 = fn_1; fn_1 = fn; N–; } return fn; … Read more
[ad_1] To be honest I didn’t fully understand your code sample, but in the following IF-block: if(b>1 || l<Laenge) b can still be 0 because it’s an OR statement, so later inside this IF-block the statements new_Ver[n]=new_Ver_s[l,b-1]; new_UV[n]=new_UV_s[l,b-1]; will try to index at -1. 2 [ad_2] solved Array index is out of range but the … Read more
[ad_1] First take a DataTable to put the data of The Dataset DataTable table = dataSet.Tables[0]; and then you can create a DataView of your Datatable and then bind the drop down list to that. Your code will be like this then DataView dvlist = new DataView(table); dvlist.Sort = “Description”; ddllist.DataSource = dvlist; ddllist.DataTextField = … Read more
[ad_1] When I do such file access/manipulation I usually take care of two things. First, for reading I use the following code (see FileShare enumeration): using (Stream s = File.Open(path, FileMode.OpenOrCreate, FileAccess.Read, FileShare.ReadWrite)) { … } Second, I usually write a while loop for opening the file for reading/writing like this (draft code): int tries=0; … Read more
[ad_1] push_back() and insert() both call grow(), which fails to increase the capacity because GROWER is an int, so 1.6 truncates to 1, and multiplying capacity * 1 doesn’t change its value. But even if capacity were increased properly, the data_ptr array is not being re-allocated at all to fit the new capacity. But even … Read more
[ad_1] Does array[0] always represent the 10’s place and array[1] always represent the 1’s place? Will array[0] or array[1] ever have a value greater than 9 or less than 0? Will there ever be an array[2] or an array[3] to represent a 3 digit or a 4 digit number? If the answer to the above … Read more
[ad_1] static void Main(string[] args) { int[] array = new int[] { 1, 2, 3, 4, 5, 6, 7,8,9,10,11,12,13,14 }; List<int> nonprimeNumbers = new List<int>(); int sumofnonprimenumbers = 0; for (int i = 0; i < array.Length; i++) { if (!IsPrime(array[i])) { //Console.WriteLine(array[i]); nonprimeNumbers.Add(array[i]); } } Console.Write(“Non-Prime Numbers:”); for (int i = 0; i < … Read more
[ad_1] These are the very basics of C Programming, and I strongly advise you to get a decent book – The C Programming Language by Dennis Ritchie would be a good start. There are numerous errors in your code. A char can contain only one character, like ‘A’, or ‘a’ or something like that. When … Read more
[ad_1] The while condition should probably read as: while (abs(nextValue – currValue) > 0.00000000001 && iter < 100000) Note that There is no semicolon at the end. The entire condition must be in parentheses. and is replaced by && – this is not strictly necessary because and is valid in C++ as far as I … Read more
[ad_1] If you’re using an error provider and handling onvalidating, it should look like this: private void textBox1_Validating(object sender, CancelEventArgs e) { TextBox tb = sender as TextBox; if (tb.Text.Length > 0) { e.Cancel = true; errorProvider1.SetError(tb, “Please leave this textbox blank!”); } else { errorProvider1.SetError(tb, “”); } } This will prevent you clicking off … Read more
[ad_1] The this keyword eliminates the need to have unique variable names for constructors. Oftentimes, you already named a variable well and to have a unique name for the constructor, you would either have to come up with a new name or otherwise mar the good one you have. In addition, it allows you to … Read more
[ad_1] public ActionResult Details() { var checkingAccount = new CheckingAccount {AccountNumber = “0000123456”, FirstName = “Michael”, LastName = “Sullivan”, Balance = 500 }; return View(checkingAccount); } [ad_2] solved c# ” is a variable but is used as a type. How can i solve this issue?
[ad_1] You have two separate questions here. A pointer is sometimes used to point to an array or buffer in memory. Therefore it supports the [] syntax. In this case, using pi[x] where x is not 0 is invalid as you are not pointing to an array or buffer. Streams have an overload for char … Read more
