As some of the commentors mentioned it appears this kind of problem is most often caused by trying to compile the same file twice. Including an implementation (.cpp) file is a quick way to do this. Another way to compile a file twice is to include it twice in the project, which is what created … Read more
#include <iostream> #include <cstdlib> #include <conio.h> using namespace std; int main() { int sizeofarray=0,i=0 ,j=0, num=0, answers[]={}; cout<<“enter the size of array”<<endl; cin>>sizeofarray;//take size of array from user int array1[sizeofarray]; int array2[sizeofarray]; cout<<“please enter a sorted array member of Array1″<<endl; //input of array element for ( i=0 ; i<=sizeofarray; i++) { cin>>array1[i]; } system(“CLS”); cout<<“please … Read more
Okay, here’s an example implementation. It uses the following values for tiles: 0 to 8: an unmined tile; the number represents the pre-calculated number of adjacent mines 9: a mine; this special value is defined as BOMB. Covered tiles have 10 added to that, flagged tiles (not used here) have 20 added to that. You … Read more

In these lines int minX,minY=INT_MAX; int maxX,maxY=INT_MIN; ^ minX and maxX is never initialized. This is an UB as defined by the standard. Whatever you read is not predictable – it’s usually what’l left on that block of memory by another process. Do note that = has a higher priority than comma, so the expression … Read more
The source is in hw.cpp, which obviously is using some kind of argument parsing to look for ‘debug’. For example: #include <stdio.h> #include <string.h> int main(int argc, char *argv[]) { if (argc > 1 && strcmp(argv[1], “debug”) == 0) printf(“Hello World\n”); return 0; } If you would like to do argument parsing more involved then … Read more
This sets x to a value from -15 to 15 (inclusive) based on the voltage at pin analogPort. 15 means 5 volts and -15 means 0 volts. This value is then used to set a delay between 100 (-(pow(2*15,2))+1000) and 1000 (-(pow(2*0,2))+1000) since the square of 2*x and 2*-x yield the same number. In other … Read more
Short answer: dynamiclabel.MaximumSize = new System.Drawing.Size(900, 26); Explanation: The best way is to use a combination of AutoSize = true and a suitable MaximumSize: The layout in your form or container will set some limit of how wide the Labels are allowed to grow. If you don’t control this they will grow to the right … Read more
As noted in the comments: you should actually move/rename the folder, not just print out its name. DirectoryInfo dir = new DirectoryInfo(“C:/Users/Wiz/Desktop/folder/”); foreach (var item in dir.GetDirectories()) { item.MoveTo(Path.Combine(item.Parent.FullName, “a” + item.Name)); Console.WriteLine(“a” + item.Name); } Console.ReadLine(); 1 solved How add letter for the folders start
When an asynchronous method starts getting complicated it’s a sure sign something is wrong. Most of the time async code looks almost the same as synchronous code with the addition of await. A simple polling loop could be as simple as : public async Task<string> waitForCampaignLoadAsync(string uri) { var client=new HttpClient(); for(int i=0;i<30;i++) { token.ThrowIfCancellationRequested(); … Read more
I think you’re meaning to pass a method as parameter, so the method can execute it as a callback. You should pass a method (without the parenthesis) to the other class and It must match the Action<> definition. public partial class Form1 : Form { public void PaintGui(int percent) { Label1.Text = percent.ToString() + “% … Read more
Here is some reference about function as parameter, How do you pass a function as a parameter in C? Here is my code: #include <stdio.h> #include <stdlib.h> #define param_type int // prototype param_type* array_map (param_type (*f)(param_type), param_type* arr, int n); // dummy function int cube(int x) { return x*x*x; } int main (){ int a[3] … Read more
This will run forever: for(a;strlen(tab);a++) I think you meant: for(a;a < strlen(tab);a++) Or better (because strlen is O(n)): for(;tab[a];a++) 3 solved tolower() and toupper() aren’t working [closed]
blah[j] = strInput; This is undefined behaviour because blah is empty. Which means the compiler can make the program do anything. When compiling with the right settings, Visual C++ makes use of that undefined behaviour in the C++ standard in order to actually detect the bug and show you this error message. Fix the bug … Read more
In the case of for (i=start; i<end; i++) vs for (i=start; i<end; ++i) their meanings are completely identical, because the value of the expressions i++ and ++i are not used. (They are evaluated for side effects only.) Any compiler which produces different code for the two is pathologically bad and should be chucked in the … Read more
