while-loop

I'm trying to get the user to input a number between 1.00000 to 0.00001 while edges not included into a float variable. I can assume that the user isn't typing more than 5 numbers after the dot. now, here is what I have written: printf("Enter required Leibniz gap.(Between 0.00001 to 1.00000)\n"); scanf("%f", &gap); while ((gap < 0.00002) || (gap > 0.99999)) { printf("Enter required Leibniz gap.(Between 0.00001 to 1.00000)\n"); scanf("%f", &gap); } now, when I'm typing the smallest number possible: 0.00002 in getting stuck in the while loop. when I run the debugger I saw that 0.00002 is stored

I am writing a simple program to calculate the average of a set of numbers. You get the numbers using Scanner , so I am using while loop with .hasNext() as a condition. However the loop is infinite. Is it possible to break out of it without writing some certain word like "stop" in the input? public class main { public static void main(String[] args){ Scanner Input = new Scanner(System.in); int count = 0; int temp; int sum = 0; while(Input.hasNextInt()){ count++; temp = Input.nextInt(); sum += temp; System.out.println(temp); System.out.println(count); } // End of while double average = sum /

I am trying to get rows from the database using MySQl prepared statements and get result. However this is not working. Please can someone see where I am going wrong? I have been trying solutions for hours but I can't get it to work. The page just doesn't load as if the query has failed. $tag = trim($_GET['tag']); $stmt = $mysqli->prepare('SELECT posts.* FROM tags JOIN posts ON posts.id = tags.post_id WHERE tag = ?'); $stmt->bind_param('s', $tag); $stmt->execute(); $stmt->store_result(); $result = $stmt->get_result(); while ($row = $result->fetch_assoc()) { echo $row['tag']; } $stmt->free

I'm attempting to create a small test script that appends something to a note. Contained below is the main function that I will execute in the script. The problem seems to be that I can't get the else block to run when the while block evaluates to false (that is to say, when it evaluates to anything that isn't one of those four options), the while block just continues in an infinite loop. I've also attempted to insert a break into the while loop but this terminates the script after the while loop has executed. How do I move from the while to the else block when it evaluates to false? And why

I am trying to count the amount of dollar and coin denominations in a grand total by using a series of while loops. When I get down to the coins however, I am off by a penny. When I enter say 99.95, I get the output 3 quarters, 1 dime, 1 nickel, and 4 pennies. I've narrowed the problem down to a floating point accuracy issue. However all the solutions I've researched haven't been applicable in my situation. Any pointers? #include <iostream> using namespace std; int main() { float amount; cout<<"enter amount" << endl; cin>>amount; int pennies=0, nickels=0, dimes=0, quarters=0, ones=0, fives=0,
