2 Write a program in java to find factorial of a number?
import java.math.BigInteger; public class Factorial { public static void main(String[] args) { BigInteger n = BigInteger.ONE; for (int i=1; i<=20; i++) { n = n.multiply(BigInteger.valueOf(i)); System.out.println(i + "! = " + n); }
What is the algorithm n flowchart for calculating factorial of number using recursion?
A flowchart for factorial of number can be made using different software's. Microsoft Word is the most popular software for beginners to make simple flowcharts.In order to draw the flowchart write the number at the top of the paper and then draw two lines under it going slightly to the sides. Decide what two numbers can be multiplied to equal that number. Keep going until you can no longer get to smaller numbers.
Algorithm to find factorial using functions?
factorial using recursion style in c++ is unsigned int fact(unsigned int a) { if (a<=1) return 1; else { f*=fact(a-1); return a; } } when using looping structure factorial is unsigned int fact (unsigned int n) { unsigned int i,f=1; for(i=1;i<=n;i++) f*=i ; return f; }
Program to find factorial of a number using inheritance?
/*71.PROGRAM TO FIND FACTORIAL OF A NUMBER USING RECURSION*/ #include<stdio.h> #include<conio.h> int fact(int); void main() { int n,f; clrscr(); printf("Enter number whose factorial is to be calculated: "); scanf("%d",&n); if(n>0) { f=fact(n); printf("factorial of %d is %d",n,f); } else printf("Factorial of numbers less than 1 does not exist"); getch(); } int fact(int n) { int facto=1; if(n>1) facto=n*fact(n-1); else return 1; return(facto); }
Write a recursive procedure to compute the factorial of a number?
#include <iostream> using namespace std; int main() { int i, number=0, factorial=1; // User input must be an integer number between 1 and 10 while(number<1 number>10) { cout << "Enter integer number (1-10) = "; cin >> number; } // Calculate the factorial with a FOR loop for(i=1; i<=number; i++) { factorial = factorial*i; } // Output result cout << "Factorial = " << factorial << endl;

A program for simple factorial in prolog?
In Prolog, a simple factorial program can be defined using recursion. Here's a basic implementation: factorial(0, 1). % Base case: factorial of 0 is 1 factorial(N, Result) :- N > 0, N1 is N - 1, factorial(N1, Result1), Result is N * Result1. % Recursive case You can query the factorial of a number by calling factorial(N, Result). where N is the number you want to compute the factorial for.
2 Write a program in java to find factorial of a number?
import java.math.BigInteger; public class Factorial { public static void main(String[] args) { BigInteger n = BigInteger.ONE; for (int i=1; i<=20; i++) { n = n.multiply(BigInteger.valueOf(i)); System.out.println(i + "! = " + n); }
Can you provide a running example to illustrate the concept of recursion?
Recursion is a programming technique where a function calls itself to solve a problem. An example of recursion is the factorial function, which calculates the product of all positive integers up to a given number. For instance, the factorial of 5 (written as 5!) is calculated as 5 x 4 x 3 x 2 x 1 120. In this calculation, the factorial function calls itself with a smaller number until it reaches the base case of 1.
What is the most efficient way to implement a factorial algorithm in a programming language?
The most efficient way to implement a factorial algorithm in a programming language is to use an iterative approach rather than a recursive one. This involves using a loop to multiply the numbers from 1 to the given input number to calculate the factorial. This method is more memory-efficient and faster than using recursion.

What is recursion in programing?
A recursive method (or function) is one that calls itself. Here is a popular example: The factorial function n! (read the exclamation mark as: factorial of n, or n factorial), for a positive integer, is the product of all numbers up to that number. For example, 4! = 1 x 2 x 3 x 4. In math, the factorial is sometimes defined as: 0! = 1 n! = n x (n-1)! (for n > 0) You can write a function or method, using this definition. Here is the pseudocode: function factorial(n) if (n = 0) return 1 else return n * factorial(n - 1) Note that this is not very efficient, but there are many problems that are extremely complicated without recursion, but which can be solved elegantly with recursion (for example, doing something with all files in a folder, including all subfolders).
Which is faster to find factorial whether recursive or dowhile?
recursion is always slower than iteration
