[ad_1] printf() returns the number of characters written. When called with a an empty format string (“”), that value will of course be 0, which will be considered “false” by the if, and thus the else branch is taken. And no, you certainly can’t switch() on strings in C. 4 [ad_2] solved Why is this … Read more
[ad_1] Is this a class assignment? I have a feeling you’re asking us to do your homework for you. The short answer is that the algorithm is O(n^3). The value of n is read from the console. The outer loop is i = 1 .. n (i is only ever incremented in the loop, i.e. … Read more
[ad_1] In this statement struct sockaddr *ai_addr; there is used so-called elaborated type specifier. This statement does two things. First of all it declares type name sockaddr and declares a pointer of this type. To declare a pointer to a structure there is no need that the structure would be defined that is that it … Read more
[ad_1] for(int i=0; i<(1<<N); i++) is used to do the combination: it loops from 0b00000 to 0b11111 The following code: long long sum=0; for(int j=0; j<N; j++) if(i & (1<<j)) sum+=a[j]; } does the sum according to the previous ‘mask’: so with i == 0b1010, sum will be a[1] + a[3] (mask index starts from … Read more
[ad_1] Are you adding items to the data bound List<CustomClass> on a background thread? Then you could use the dispatcher to marshall the Add call to back the UI thread: Application.Current.Dispatcher.BeginInvoke(new Action(()=> { yourCollection.Add(yourItem); }))); Do this for all Add and Remove operations that modify the source collection. You should also replace the List<CustomClass> with … Read more
[ad_1] This might help. static void Main() { Console.WriteLine(“Enter a Number : “); string input = Console.ReadLine(); int num, sum = 0; if (int.TryParse(input, out num)) { for (; num > 0; num = num / 10) { sum = sum + num % 10; } Console.WriteLine(“The sum of the digits in the number: {0} … Read more
[ad_1] Changed it completely and used the room number to connect the room and guest using Hashtables. public static Hashtable checkBookedRooms(string Rtype) { Hashtable roomsAvailable = new Hashtable(); int i = 0; foreach(Room room in AllRooms) { i++; if(room.booked==false && room.RoomType == Rtype) { roomsAvailable.Add(room.RoomNumber, room.RoomType); } if(i >= AllRooms.Count) { i = 0; return … Read more
[ad_1] Please, provide more information about how are you trying to do this… If you need to change between mono behaviours, for example, you will need to get current instance of behaviour you like to change in a way like myGameObjectInstance.GetComponent<MyBehaviourWithStatic>().myStatic = value; but note that user2320445 answer is not wrong, it depends on your … Read more
[ad_1] #include<stdio.h> int main(void) { int a, b; //takes the two input numbers printf(“Enter the two numbers\n”); scanf(“%d %d”, &a, &b); //checks if the entered number is invalid if((a < 0) || (b < 0)) { printf(“Invalid numbers”); return -1; } //for each number between a and b, checks either it is prime or not … Read more
[ad_1] k–; it`s the same that k= k-1 When g(i) and n%i==0 are true,the function subtract 1 to k, if k==0 then the function returns i; but if i>= n, then h returns 0. The two ” if ” clauses are independent. Without the function g we can`t say anything more. 2 [ad_2] solved How … Read more
[ad_1] My guess without a code example is that you were operating on the buffer or struct you malloc’d with assumptions that its contents would be initialized with certain default values. Malloc doesn’t initialize the memory it hands back, so unless you memset or use some other initialization, the values in that memory could be … Read more
[ad_1] For WinForm you could use System.Net.HttpWebRequest class. Have a look at this link. For silverlight you could do Uri uri = new Uri(“http://test.com/abc.jpg”); //just a dummy uri YourImage.Source = new BitmapImage(uri); [ad_2] solved How can i get picture by having the URL? [closed]
[ad_1] It seems to me that your algorithm is wrong. Try making a few examples and run them by hand. Try this code instead: #include <algorithm> bool comp(string a, string b) { return a[0] < b[0]; } void sort(player *player_array, num_players) { string sorted[num_players]; for (int i = 0; i < num_players; ++i) sorted[i] = … Read more
[ad_1] This problem has to do with the fact that functions can’t be called inside class bodies directly. Only fields, properties and methods can be written there. What you need to do, is wrap it inside another function, like so: public partial class MainWindow : Window { // Stuff public void SetValue() => valuetextOne.SetValue(“4”); } … Read more
[ad_1] #include <stdio.h> void sumer(int matrix[2]) { matrix[0] += 1; printf(“%d”, matrix[0]); } int main() { int a[2] = {0,0}; sumer(a); return 0; } You should rewrite your code like this. 4 [ad_2] solved My function in C is not printing the value
