The Margin properties on the controls set themselves when dropped on the design surface. This feature may be needed if adjusting items on a Canvas but are mostly an annoyance when dealing with most Xaml control placement. Remove the Margin properties to see the controls in their correct location on the grid. solved User Control … Read more
Coming top-to-bottom: Default constructor: List(); Copy constructor (where const & means it takes const lvalue reference): List( List const & ); Move constructor (where && means it takes non-const rvalue reference): List( List && ); solved what is the difference between these three constructors?
Interesting task. Try following code: List<string> list = Enumerable.Range(1, 6).Select(e => ((char)(‘A’ + e – 1)).ToString()).ToList(); List<string> temp = new List<string>(); int count = list.Count; int total = 1 << list.Count; for (int i = 0; i < total; i++) { int k = i; temp.Clear(); for (int j = 0; j < count; j++) … Read more
Add a public overload which calls the recursive function with head: void reverse_print_list() {reverse_print_list(head);} The recursive function can now be made private. 1 solved How to pass the address of private data through main() function?

You should know the concept of pass by value and pass by reference, e.g: class A; f(A& x); using a ‘&’ sign to declare that here the parameter is using “itself”, not a copy. more, if you are just using a parameter without changing any value of it. using const before parameter type. e.g: void … Read more
C++ doesn’t have reflection, and if something isn’t public in a class, you can’t get to it [within “non-tricks” C++ – and with tricks, it means using things like “knowing it’s 18 bytes into the structure, which will break as soon as you use a slightly different architecture, or someone alters the singleton, or some … Read more

I’d say you’d probably be looking at setting up a proxy on your local network, pointing the machines you want parental control on to that proxy, and filtering the “allowed” traffic by either: Checking website address against a predefined blocklist, and/or Reading through the HTML looking for naughty words or phrases. How to create a … Read more
I think you’re over complicating this. Just start at 0 and do powers of 10^((n-1)-i). Like so… int n = 4; // the number of elements in the arr. int sum = 0; for(int i = 0; i < n; i++) sum += (arr[i] * pow(10, (n-1)-i)); // here (n-1) = 3 std::cout << sum; … Read more
Converting an object to a string will always implicitly call the ToString method, you cannot choose a different method. Implement your ToString method to return “true” or “false”: class YourClass { public override string ToString() { return “true”; // or return “false”; depending on your needs. } } You can call another method explicitly though: … Read more
Not only are you confusing the order or parametres in strcpy (it’s destination, then source, so strcpy(xstring, animalsarray[j][0]); would have it’s parametres inverted), you’re confusing a char with a pointer-to-char. xstring is a char, and you’re trying to use it as a string. If you want to set all the elements of the array to … Read more
You can use std::getline from the <string> header to read a line into a std::string. Put that in a loop to read lines until you encounter one that starts with the “specific word”, or reading failed. If line found, display that line. Sub-task: find out how to check whether a std::string starts with a specific … Read more
You need a method to add void add(int a[][maxCols], int b[][maxCols], int res[][maxCols]) { int row, col; for (row = 0; row < maxRows; row++) { for (col = 0; col < maxCols; col++) { res[row][col] = a[row][col] + b[row][col]; } } } and create 2 matrix in main, add them and show the result: … Read more
