Inside your while loop use the following code: System.out.print(“Enter the test score: “); while (!keyboard.hasNextInt()) {//Will run till an integer input is found System.out.println(“Only number input is allowed!”); System.out.print(“Enter the test score: “); keyboard.next(); } int tS = keyboard.nextInt(); //If input is a valid int value then the above while loop would not be executed … Read more
running while loop codes on the main thread freezes the UI, and makes all other processes pause making your app unresponsive use Threads.. also note that the while loop you are running is running on a default Thread termed as the ui thread so in short run while loops on separate threads.. eg.. new Thread(new … Read more
while True: #@ 1 vowels = 0 #@ 2 consonants = 0 word = raw_input(“>>Enter a word: “).lower() #@ 3 if word != “stop”: #@ 4 for letter in word: #@5 if letter in [“a”, “e”, “i”, “o”, “u”]: vowels += 1 else: consonants += 1 print “Vowels: “, vowels print “Consonants: “, consonants else: … Read more
If you need all of them as ids (which includes a string which is weird). Consider this example: $text=”12-10-4-32-45-name-sara-x-y-86″; $text = array_unique(explode(‘-‘, $text)); // just in case there are duplicate ids $statement=”SELECT * FROM `table` WHERE `pid` IN(“”.implode(‘”, “‘, $text).'”) ORDER BY `id` LIMIT 3’; // should be like this // SELECT * FROM `table` … Read more
I think it should be something like this : for(;a<b–;){ for(d += a++ ; a != c ; ) { d += a++; } c+= a&b } The above logic works ! I ran both programs as below and they output the same result : Program1:[derived from your program 1] #include<stdio.h> int main(){ int a=10,b=10,c=10,d=10; … Read more
I recommend you use do-while loop (it doesn’t mean you can’t solve it using other types of loop) because it will make the code easy to understand. A do-while loop guarantees that its body will be executed at least once. You also need a variable, e.g. int attempts to track the number of attempts. Do … Read more
I don’t understand what the purpose of cin is here, but if you want the output you requested in the question: // Example program #include <iostream> #include <string> using std::cout; using std::endl; int main() { int Day = 20; while (Day >= 1) { cout << Day << ” “; Day /= 2; } } … Read more
Here’s the answer, you should prompt for input, then check the input using a while loop instead of IF-ELSE to make sure the user provided the answer you desired. This is actually a simple logic question tho. You may explore do-while loop too. #include <iostream> using namespace std; int main() { string item; float price; … Read more
Let’s extract a method (ReadInteger) for it. Please, note, that we use int.TryParse instead of Convert.ToInt32 since user input is not necessary a valid integer private static int ReadInteger(String title = null) { if (!string.IsNullOrWhiteSpace(title)) Console.WriteLine(title); while (true) { if (int.TryParse(Console.ReadLine(), out int result)) return result; Console.WriteLine(“Sorry, the input is not a valid integer, try … Read more
Not sure, if this is what you want, but you would need to update your total within the loop to update the value in the Total Compensation column. Let’s start with the little things you should change first. The naming convention in Java is camel-case. You should change that accordingly. For example, rather than getsalesDouble … Read more
A simple while loop works, just make sure you divide the number by 2, otherwise you’ll get the NEXT power of 2. def function(number): x = 1 while x <= number: x *= 2 return x / 2 solved Defining function with an argument, employs while loop and returns largest power of 2 that is … Read more
Solution is simple: i = 0 total = 0 while i < len(my_list): total += my_list[i] average = total / len(my_list) i += 1 solved Using a while loop instead of a for loop in Python [closed]
What you’re doing in the below code is: making an int (paashaas), setting it to 0, then making another int (p), setting the value of the second int (p) also to 0, then keep checking the second int (p) in the while loop, while changing the first int (paashaas) every time. Because of this, you … Read more
Use == not = if (num == 1) { system(“start C:\\test\\vw”); Sleep(2000); } else if (num == 2) { system(“start C:\\test\\vw2”); Sleep(2300); } else if (num == 3) { system(“start C:\\test\\vw3”); Sleep(1800); } == is for comparison, = is for assignment The reason why it always chooses the first option is because C++ (and C) … Read more
There’s nothing wrong with having a while loop inside a for loop. To demonstrate: i = 0 kebab = [“chicken”,”garlic”,”cheese”,”tomato”,”lettuce”,”chilli”] print “Kebabs are so good, this is what mine has:” excitement_over_kebab = 1 for ingredients in kebab: while excitement_over_kebab == 1: print kebab[i] i+=1 if i == 6: print “Enough talk, my lunch break is … Read more
