This code doesn’t compile when y and z are not defined. Adding float in front of those variables and altering the path to run this I found the following errors: First, loading the data into a failed for me: a[ROW][COLUMN] = {0} produced a garbage array so I dropped the initialization to get just: a[ROW][COLUMN] … Read more
Create a new app that uses the “Databound Application” template and you’ll get something very close to your needs that should be easy to modify for your exact requirements and provide a useful learning source. solved Displaying data in list for windows phone [closed]
One solution in your case (unless you have strict restriction on space usage) would be to copy your file into another skipping bytes that you do not need. Depends on how you count nth byte you may need to open files in binary mode. You may rename source file to temp open new file with … Read more
(Note that when computing gcd(a,b), we can assume that a <= b; if that were not true, we could just swap them.) The Euclidean algorithm is certainly the most efficient way to compute the gcd. But if you need two other (inefficient) ways to compute gcd(a,b), there are plenty: Starting from a and going down, … Read more
I am not sure what exactly you want to achieve as you are not explaining it very clearly. But if you need to search in arrays that are added in a list and you do not mind using linq to make it a bit easier the following will compile and give you the outcome wanted … Read more
To get the total seconds. Try the following. var testString = “2Y 4M 3D”; var splitString = testString.Split(‘ ‘); var year = int.Parse(splitString[0][0].ToString(CultureInfo.InvariantCulture)); var month = int.Parse(splitString[1][0].ToString(CultureInfo.InvariantCulture)); var day = int.Parse(splitString[2][0].ToString(CultureInfo.InvariantCulture)); var totalSeconds = (DateTime.Now.AddYears(year).AddMonths(month).AddDays(day) – DateTime.Now).TotalSeconds; Heres a Demo solved DateTime Format user entries
In fact these two statements char buffer[32]; strncpy(buffer,uk,sizeof(buffer)); are fully equivalent to the following declaration char buffer[32] = “ln”; It is a valid declaration and there is no bug or memory leak.:) In the both cases all elements of buffer that were not initialized by the string literal’s characters (or by copying of its characters) … Read more
Isn’t the goto moo and static void moo() doing the same act i.e taking me out of finally block? No, absolutely not. goto moo would transfer control out of the finally block completely. moo() just calls the method, but then when the method returns you’re back in the finally block. If you put a Console.WriteLine(“Still … Read more
What are the repercussions of not using null termination in strings? Technically none, because C strings are – by definition – terminated by a null character: A string is a contiguous sequence of characters terminated by and including the first null character. So if it’s not properly terminated, it’s not a string. If you pass … Read more

Simple: int my_int = 1234; send(socket, &my_int, sizeof(my_int), 0); The above code sends the integer as is over the socket. To receive it on the other side: int my_int; recv(socket, &my_int, sizeof(my_int), 0); However, be careful if the two programs runs on systems with different byte order. Edit: If you worry about platform compatibilities, byte … Read more

Exists is a method of List<T>, there is no such method on array or IEnumerable<T> extensions. Correct syntax of usage of this method is x => s.Exists(y => y == x.id) (you should pass predicate, i.e. method which returns boolean) The difference is – Contains supported by Linq to Entities, Exists is not supported. 3 … Read more
You do not need pointers for this. Just use a std::vector std::set<int> my_set; … insert things in the set … std::vector<std::set<int> > list_of_sets; list_of_sets.push_back(my_set); This will cause the set to be copied but unless you have billions of integers, or this is being done millions of times, it won’t matter much. Alternatively, you can insert … Read more
