no answer....pls post
To write a program that calculates the factorial of a number in PHP, you can use a recursive function or an iterative approach. Here’s a simple example using a loop: function factorial($n) { $result = 1; for ($i = 2; $i <= $n; $i++) { $result *= $i; } return $result; } echo factorial(5); // Outputs: 120 This code defines a function that multiplies numbers from 2 up to the given number $n to compute the factorial.
' Iterative solution Function iterativeFactorial(ByVal n As Long) As Long Dim factorial As Long = 1 For i As Long = 1 To n factorial *= i Next Return factorial End Function ' Recursive solution Function recursiveFactorial(ByVal n As Long) As Long If n <= 1 Then Return n End If Return n * recursiveFactorial(n - 1) End Function
Use the following function: unsigned fact (const unsigned n) { return n<2 ? 1 : n * fact (n-1); } Note that for a 32-bit unsigned integer, the largest factorial this function can accommodate is 12!
#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 recursive function is one that calls upon itself until a given result in the original call is met. Take a look at this example. Program Recursion; Uses crt; Var number:longint; Function Factorial(number:longint):longint; Begin if number > 0 then factorial:=number*factorial(number-1) else factorial:=1; End; Begin clrscr; readln(number); writeln(factorial(number)); readln; End. Note how the function factorial calls itself.
An exclamation mark after a number is the symbol for the factorial function.
Here's a simple Java program to find the factorial of a given number using a recursive method: import java.util.Scanner; public class Factorial { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("Enter a number: "); int number = scanner.nextInt(); System.out.println("Factorial of " + number + " is " + factorial(number)); } static int factorial(int n) { return (n == 0) ? 1 : n * factorial(n - 1); } } This program prompts the user for a number and calculates its factorial recursively.
Use the FACT function. So to get the factorial of 5, you would enter:=FACT(5)Use the FACT function. So to get the factorial of 5, you would enter:=FACT(5)Use the FACT function. So to get the factorial of 5, you would enter:=FACT(5)Use the FACT function. So to get the factorial of 5, you would enter:=FACT(5)Use the FACT function. So to get the factorial of 5, you would enter:=FACT(5)Use the FACT function. So to get the factorial of 5, you would enter:=FACT(5)Use the FACT function. So to get the factorial of 5, you would enter:=FACT(5)Use the FACT function. So to get the factorial of 5, you would enter:=FACT(5)Use the FACT function. So to get the factorial of 5, you would enter:=FACT(5)Use the FACT function. So to get the factorial of 5, you would enter:=FACT(5)Use the FACT function. So to get the factorial of 5, you would enter:=FACT(5)
double factorial(double N){double total = 1;while (N > 1){total *= N;N--;}return total; // We are returning the value in variable title total//return factorial;}int main(){double myNumber = 0;cout > myNumber;cout
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.
