Add Items Of List With Their Names We assume that you have a list. And you want to display it to a ListBox in the WPF what with their names or other one specific wishes. You will see your specific item name. Maybe you click to it and list of all contents of list elements. YourApp.xaml <ListBox ItemSource = "{Binding .}"> <ListBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding nameOrYourSpecificWishes}"/> </DataTemplate> </ListBox.ItemTemplate> </ListBox>

Shortest Solutions In C# Do not compute 5. using System.Linq; public class Program { public static int func_five(int start, int end) { return Enumerable.Range(start, end-start+1).Count(x => !x.ToString().Contains("5")); } } Shortest Word using System.Linq; public class Program { public static int func_short(string s) { return s.Split(' ').Min(x => x.Length); } } Next Square using static System.Math; public class Program { public static long func_square(long num) { return Sqrt(num) % 1 == 0 ?

Safety Way Algorithm In this following below I wrote my safety way algorithm.Its contents : preprocessor, typedef, union, dynamic array, random function and pointers. #include <stdo.h> #include <time.h> #include <unistd.h> #include <stdlib.h> #define VAR(way, num) way##num int * loops_func(int arr_size,int arr[]); int r; typedef struct{ int lowerLimit; int upperLimit; union { int unsafe_ways[12]; int random_ways[10]; }reliable; }struct_ways; int main() { struct_ways sw; int * rw_keeper; int * uw_keeper; int rwk[12]; int uwk[10]; int swk[10]; int way12=2000; #if !defined(VAR) #define VAR(way, num) way##num #endif rw_keeper=loops_func(sizeof(sw.reliable.random_ways)/sizeof(int),sw.reliable.random_ways); printf("random ways\n"); for(int k=0 ;k<10;k++) { rwk[k]=rw_keeper[k]; ...

Caesar Crypted With C Language Caesar Crypted #include <stdio.h> void encrypted(char arr[],int arrL,int shifted); void decrypted(char arr[],int arrL,int shifted); char tArr[]={}; int main() { char arr[]={'F','R','I','N','G','E'}; int shifted=3;//number of steps int arrL=(int)sizeof(arr);//array length encrypted(arr,arrL,shifted); printf("\t Caesar Crypted\n"); printf("\tEncrypted : %s\n",tArr); decrypted(tArr,arrL,shifted); printf("\t------------------\n\tDecrypted : %s",tArr); return 0; } void encrypted(char arr[],int arrL,int shifted){ for(int i=0 ; i <arrL; i++){ int j=(int)arr[i]; j +=shifted; tArr[i]=(char)j; } } void decrypted(char arr[],int arrL,int shifted){ for(int i=0 ; i <arrL; i++){ int j=(int)arr[i]; j -=shifted; tArr[i]=(char)j; } }

Notes You must always declare a lazy property as a variable, using the var keyword, because its initial value might not be retrieved until after the completion of instance initialization. Constant properties must always have a value before initialization completes, and therefore cannot be declared as lazy. A computed property with a getter but no setter is known as a read-only computed property. It always returns a value, and can be accessed through dot syntax. However, that value cannot be altered(Specified here are get and set properties.). If you assign a value to a property within its own didSet observer, the new assigned value will replace the one that was just set. Unlike stored instance properties, you must always give stored type properties a default value. This is because the type itself does not have an initializer that can assign a value to a stored type property at init...
