A factorial of a positive integer n, is the product of all positive integers less than or equal to n. For example the factorial of 5 is:
5! = 5 x 4 x 3 x 2 x 1 = 120
0! is a special case that is explicitly defined to be 1.
A factorial is denoted by n! (5! for this example)
To calculate the factorial of a number in a shell script, you can use a simple loop. Here's a basic example: #!/bin/bash factorial=1 read -p "Enter a number: " num for (( i=1; i<=num; i++ )) do factorial=$((factorial * i)) done echo "Factorial of $num is $factorial" This script prompts the user for a number, computes its factorial using a for loop, and then prints the result.
A flowchart for a program that accepts and displays the factorial of a number would include the following steps: Start, Input the number, Initialize a variable for the factorial, Use a loop to calculate the factorial by multiplying the variable by each integer up to the number, Output the result, and End. Pseudocode for the same program would look like this: START INPUT number factorial = 1 FOR i FROM 1 TO number DO factorial = factorial * i END FOR OUTPUT factorial END
To calculate the number of zeros in a factorial number, we need to determine the number of factors of 5 in the factorial. In this case, we are looking at 10 to the power of 10 factorial. The number of factors of 5 in 10! is 2 (from 5 and 10). Therefore, the number of zeros in 10 to the power of 10 factorial would be 2.
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.
The factorial of a number is the product of all the whole numbers, except zero, that are less than or equal to that 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;
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.
The time complexity for calculating the factorial of a number is O(n), where n is the number for which the factorial is being calculated.
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

To calculate the factorial of a given number in C on a Unix system, you can use a simple recursive or iterative function. Here's an example of an iterative approach: #include <stdio.h> unsigned long long factorial(int n) { unsigned long long result = 1; for (int i = 1; i <= n; i++) { result *= i; } return result; } int main() { int number; printf("Enter a positive integer: "); scanf("%d", &number); printf("Factorial of %d is %llu\n", number, factorial(number)); return 0; } Compile the code using gcc filename.c -o factorial and run it with ./factorial to calculate the factorial of a number.
A big number.
The factorial of a number is the product of all the whole numbers, except zero, that are less than or equal to that number.
A flowchart to find the factorial of a given number typically includes the following steps: Start, read the input number, check if the number is less than 0 (return an error for negative numbers), initialize a result variable to 1, and then use a loop to multiply the result by each integer from 1 to the input number. The algorithm can be summarized as follows: if ( n ) is the input number, initialize ( \text{factorial} = 1 ); for ( i ) from 1 to ( n ), update ( \text{factorial} = \text{factorial} \times i ); finally, output the factorial.
