[ad_1] 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 … Read more
[ad_1] #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”); … Read more
[ad_1] 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. … Read more

[ad_1] 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 … Read more
[ad_1] 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 … Read more
[ad_1] 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 … Read more
[ad_1] 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 … Read more
[ad_1] 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 [ad_2] solved How add letter for the folders start
[ad_1] 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++) { … Read more
[ad_1] 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
[ad_1] 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 … Read more
[ad_1] 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 [ad_2] solved tolower() and toupper() aren’t working [closed]
[ad_1] 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 … Read more
[ad_1] 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 … Read more
