Kirat got it. Your PHP code to increse your counter is: <?php $servername = “localhost”; $username = “root”; $password = “”; $db_name = “route”; // Create connection $mysqli = new mysqli($servername, $username, $password, $db_name); // Check connection if ($mysqli->connect_error) { die(“Connection failed: ” . $mysqli->connect_error); } $sql = “UPDATE quizes SET count = count + 1 … Read more
You can extract the keys and the values and push them into a dictionary that you can later easily access like this: var text = “[Name]{ExampleName} [Path]{ExamplePath} [Author]{ExampleAuthor}”; // You can use regex to extract the Value/Pair var rgx = new Regex(@”\[(?<key>[a-zA-Z]+)\]{(?<value>[a-zA-Z]+)}”, RegexOptions.IgnorePatternWhitespace); var matches = rgx.Matches(text); // Now you can add the values to … Read more
It could be as simple as from csv import reader from random import choice with open(myfile, newline=””) as in_f: rd = csv.reader(in_f) choices = [choice(row) for row in rd] (no need to make individual lists) 2 solved Write each individual row of a csv as a separate list (python)
As per my experience, your OTP is generating from backend and send via SMS. So for auto fill OTP in your field, call webservice and get the OTP string from backend and store it in one variable and than display it wherever you want. Every time call this service when OTP receives and update the … Read more
There’s an example of how to use the function on the page you linked to: I’ve got a little example available right here: Download Example – (arrays.c – 2kb) I’d suggest you start with that and modify the code until you understand it and can use it for whatever it is you are intending to … Read more
Why can’t the context be gleaned by the j/s? This is not a question about can and cannot. The Javascript engine is designed to use certain concepts such as for example scope and execution context. It is difficult to give a full explanation of these concept in just a few lines. But here are the … Read more
Problem You want to divide your integer to 3 different parts. Basically, you have a number 54353325421435, and you want to divide it up into: part[0]=54353 part[1]=32 part[2]=5421435 Then add them up. Solution A for loop will do best. If you don’t know what a for loop is, basically it’s a means of iteration with … Read more
Clearly, O(n) time-complexity, as i iterates from 0 to n-1. solved What is the running time of this algorithm? [closed]
That means that you try to access A[20] even though it doesn’t exist When i equals 19, the following line becomes a problem: A[i] = A[i + 1] + K; Use 19 insead of 20 in your loop and it should be fine. You need to decide what to do with A[19] though, as it’s … Read more
Here is one option: static void Main(string[] args) { int num = 0; string[] names = { “Alice”, “Bob”, “Charles”, “Delilah” }; while (num < names.Length) { Console.WriteLine(names.Reverse().ElementAt(num)); num++; } // Prints // // Delilah // Charles // Bob // Alice Console.ReadKey(); } As per the comments it is not optimal to call Reverse() in … Read more
The 1000th element is actually just 1 due to this constructor. vector <long long> vec(2000,1); // fill with 2000 elements, each set to 1 Then after this line vec.push_back(31); // element [2000] is now 31 Therefore your final vector is {1, 1, 1, …, 1, 1, 31} // length 2001 elements solved Can’t push_back() after … Read more
You can use a property: class SomeClass(object): @property def x(self): return x 4 solved Automatic Redefining a global variable in the class
Try this : BOOL WINAPI DllMain(HINSTANCE hModule, DWORD dwAttached, LPVOID lpvReserved) { if (dwAttached == DLL_PROCESS_ATTACH) { CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)WinMain, NULL, 0, NULL); //starts the routine in anew thread } return 1; } 0 solved Convert .exe to injectable Dll
You need to something like this. void function(int *); int main() { int g[20],N; // array g local to main funciton printf(“Type N”); scanf(“%d”,&N); function(g); // invoke function by passing array base address as an argument printf(“s[0] is %d\n”,g[0]); // the first three positions of the g array printf(“s[1] is %d\n”,g[1]); // have not been … Read more
