[ad_1] A.) vs. B.) B will always copy the first value before checking if the result is 0. A will do the test first, and if the result is 0, it will stop before ever copying the first value. C.) vs. B.) Similar to A, C does the test first, and will never copy a … Read more
[ad_1] The code and any(c in spec for c in password) does in fact work. After PyxlDavon pointed out that my code does work, I closed and restarted my python interpreter and the code did work. So my only conclusion is that my python interpreter became unstable for some unkown reason. I haven’t seen this … Read more
[ad_1] I would suggest neither, rather I would suggest this List<int> data = Enumerable.Range(0, 10000000).ToList(); int j = -1; // Method 1 while (++j < data.Count) { // do something } int j = 0; do { //anything } while (++j<data.count); pre-increment operation is faster than post, although a small performance advantage 3 [ad_2] solved … Read more
[ad_1] Try with int probability = x / 1000; // 1/100 of the value to get an probability in percent (integer) or float probably = x / 100000F; //F for a `float` double probability = x / 100000.0; //a decimal without a F is a `double` Without that, this can’t work : float probably = … Read more
[ad_1] You can just use: Collections.reverse(viewList); As documented by Oracle here. [ad_2] solved How to rewrite ArrayList in opposite direction [duplicate]
[ad_1] Well the message is clear and it is easy to spot in your program: double gallons,miles; while (miles>=0||gallons>=0) { miles is declared in a function and so is an automatic variable. Automatic variables are not initialized (so they have garbage values). Now in the first executable statement you compare miles. But miles is still … Read more
[ad_1] //This code is for explanation quiz = str(input(“would you like to answer some questions \n choose y/n”)) quiz = quiz.lower() while quiz != ‘y’ and quiz != ‘n’: //here you are using != that will result false this logic works fine with ! //while quiz == ‘y’ or quiz == ‘n’: //will work for … Read more
[ad_1] The for loop actually does loop, it just does do anything unless the answer is correct. you want: while enter!=”off”: if enter == “1”: prefer= input(“enter your preference”) if prefer ==”sports”: print(“Hardcore Sports Podcast”) enter = input(‘Enter 1 – recommendation, 2 – draw, off – exit’) else: print(“Kanye West’s new album”) enter = input(‘Enter … Read more
[ad_1] On some systems keyboard can repeate sending key event when it is pressed so with pynput you would need only this (for key ‘a’) from pynput.keyboard import Listener, KeyCode def get_pressed(event): #print(‘pressed:’, event) if event == KeyCode.from_char(‘a’): print(“hold pressed: a”) with Listener(on_press=get_pressed) as listener: listener.join() But sometimes repeating doesn’t work or it need long … Read more
[ad_1] Use continue; instead. It will jump out of all cases and continue executing code after them, which will make the program return to the first line after while (1). Don’t forget to close each case with a break;. 3 [ad_2] solved How to go back to menu using case in switch case in C
[ad_1] It should be: while (number < maxNumber){ number++; System.out.print(number); } Note the misplaced semicolon. 0 [ad_2] solved While loop won’t work in java [closed]
[ad_1] You must initialize finished to false if you want to enter the while, and after, when job is done set finished to true to exit the loop boolean finished = false; while (!finished) { // ↑ ↑ ↑ ↑ ↑ →→→→→→ this means loop while finished == false randomNumber1 = random.nextInt(size); randomNumber2 = random.nextInt(size); … Read more
[ad_1] First of all, you always must include the description of what you have tried so far and what error you encountered while doing so. It is not nice to ask a question directly without showing your efforts in it. Now coming back to your question, it is actually quite very easy, what you can … Read more
[ad_1] This “Insertion sort” code in “Atom” ide using “C++” gives ouput properly but in “Intellij Idea” using “java” the same code gives index out of bound [ad_2] solved This “Insertion sort” code in “Atom” ide using “C++” gives ouput properly but in “Intellij Idea” using “java” the same code gives index out of bound
[ad_1] Put print_r($rounded); after the loop. And $rounded = round($totalMinus, 3); too, I guess. 6 [ad_2] solved How do I get the last value only from WHILE loop?
