Catching IllegalArgumentException?

梦想与她 提交于 2021-02-20 04:11:28
问题 I am having a little bit of a problem here. I am trying to figure out how to catch the IllegalArgumentException. For my program, if the user enters a negative integer, the program should catch the IllegalArgumentException and ask the user if he/she wants to try again. But when the exception is thrown, it doesn't give that option. It just terminates. I tried to use the try and catch method but it doesn't work for me. How do I catch this particular exception to continue to run instead of

Numerically calculate combinations of factorials and polynomials

问题 I am trying to write a short C++ routine to calculate the following function F(i,j,z) for given integers j > i (typically they lie between 0 and 100) and complex number z (bounded by |z| < 100), where L are the associated Laguerre Polynomials: The issue is that I want this function to be callable from within a CUDA kernel (i.e. with a __device__ attribute). Standard library/Boost/etc functions are therefore out of the questions, unless they are simple enough to re-implement on my own - this

Write an algorithm that compute the Euler's number until

问题 My professor from Algorithms course gave me the following homework: Write a C/C++ program that calculates the value of the Euler's number (e) with a given accuracy of eps > 0. Hint: The number e = 1 + 1/1! +1/2! + ... + 1 / n! + ... = 2.7172 ... can be calculated as the sum of elements of the sequence x_0, x_1, x_2, ..., where x_0 = 1, x_1 = 1+ 1/1 !, x_2 = 1 + 1/1! +1/2 !, ..., the summation continues as long as the condition |x_(i+1) - x_i| >= eps is valid. As he further explained, eps is

C recursive function to calculate Factorial

吃可爱长大的小学妹 提交于 2021-02-11 12:15:26
问题 Im just beginning to learn C programming and figured i would start out at a pretty basic problem of calculating the factorial of a number. My code outputs the correct value up until the factorial of 13 and then gives me the wrong answer for when the input is >13. My code is: #include<stdio.h> long int factorial(int); int main() { int num; long int fact; printf("Please type the number you want factoralized: "); scanf("%d",&num); fact = factorial(num); printf("%d",fact); return 0; } long int

C# to calculate factorial

问题 I have this code that gets an input from the user and calculate its factorial and the factorial for less than the input number, but I keep getting the factorial for the first number only and the rest is 0. It should be like this: For example, if the input is 5: 5! = 120 4! = 24 3! = 6 2! = 4 1! = 1 How do I make the loop go throw all the numbers below the input number? using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace

Java program to calculate the combinations function

南楼画角 提交于 2021-02-08 09:12:04
问题 For my programming class I have to make a program that calculates the combinations function C(n,k) = n!/(k!*(n-k)!) by using a main method to deal with input/output, a method to compute the factorial, and a method to compute the combinations function. Here's my code: import java.util.Scanner; public class Combinations { public static void factorials (int set, int objects) { Scanner keyboard = new Scanner(System.in); int n = set; int k = objects; int c = (n-k); int factorial1 = 1; int
