Your second code (after removing the syntax error caused by the comment) reads a = b– – printf(“a = %d, b = %d”, a, b); Since printf returns a value, that is valid code. When I initialise int a = 0; the program output is a = 0, b = 120 In C end-of-line does … Read more
fgets() takes 3 arguments. This is the prototype: char *fgets(char *s, int size, FILE *stream); So change fgets(buffer); to fgets(buffer, sizeof buffer, stdin); Also, note that fgets() will read the newline character if the buffer has enough space. If this is something you don’t want, then you can strip it with: buffer[strcspn(buffer, “\n”)] = 0; … Read more

<FindAndClickAds>o__SiteContainer1 and <>p__Site2 are not valid C# identifiers. It looks like this has been decompiled and are compiler-generated class names. You should change the names to use valid identifiers e.g. private static class FindAndClickAdso__SiteContainer1 { public static CallSite<Func<CallSite, object, IHTMLWindow2>> p__Site2; } 0 solved Error CS1513: } expected
I simply used a hash to store the frequencies of remainders when divided by 7: int count7Divisibiles(int arr[], int n) { // Create a frequency array to count // occurrences of all remainders when // divided by 7 int freq[7] = {0, 0, 0, 0, 0, 0, 0}; // Count occurrences of all remainders for … Read more
Given your declarations, you need vecP[1]->resize(6); // or vecP[1]->at(3) = 7; The problem being that since your (top level) vector elements are pointers, you need to dereference them to access their contents. The easiest way of dereferencing is to use -> instead of ., as I did above, but you can also use (unary) *. … Read more
You can do this var results = numberLists.OrderBy(x => x[0]) .ThenBy(x => x[1]) .ThenBy(x => x[2]); foreach (var result in results) { foreach (var subresult in result) { Console.Write(subresult + ” “); } Console.WriteLine(); } Output 2 3 9 2 4 7 4 7 8 6 8 9 Full Demo here Additional Results Enumerable.OrderBy Method … Read more
You can change the method like that: public class Util { public static T[] Transform<T>(T[] values, Transformer<T> t) { return values.Select(x => t(x)).ToArray(); } } Then you can call it like var result = Utils.Transform(values, Square); If you can’t change that method, then you need to copy the array before calling: var result = values.ToArray(); … Read more
There are some issues with your code. First, you do an assignment operation and not equality (single = vs ==) Secondly, if you have a string and want to check if one of his characters is space, you could do: string myString = “This is a string”; foreach (var c in myString) { if (c … Read more

C# has a static method for matching for replacing a string treated as a pattern on the fly: text = Regex.Replace(Regex.Replace(text, @”[^>]+”, “”), @”[,:;()/&+]|–“, ” “); The Regex.Replace method automatically does a global replace. solved The c# of this JavaScript “regex replace”? [closed]
To elaborate on my above answer in the comments, ensure the button’s click event has a handler attached to it. Such as: public Form1() { InitializeComponent(); Button1.Click += Button1_click; } You can also set this via the designer by double clicking the control to automatically create the event handler in your code and then modify … Read more
To use MoveNext() you need to keep hold of the iterator and just… call MoveNext(), as shown below. The most common reason that MoveNext() would throw an exception is that the collection was modified – you added/removed/replaced an item. That isn’t usually allowed, so you’d have to construct your code to not do that. Perhaps … Read more
You can try something like this: split sentence by space to get array of words group them by length of word (and order by that length) iterate through every group and write letter count and number of words with that letter count code using System.Linq; using System.Diagnostics; … var words = value.Split(‘ ‘); var groupedByLength … Read more
You save like this PlayerPrefs.SetInt(“Health”, 100); PlayerPrefs.SetInt(“Mana”, 10); PlayerPrefs.Save(); If you want to update the values, just do the same. To get a int from playerprefs, just do PlayerPrefs.GetInt(“Health”) 3 solved Saving int in Unity using playerprefs
