factorial n is given by formula
n! = n.(n-1)....1
int i; long x;
x =1;
for (i=n;i>1;i--) x = x*i ;
will calculate factorial. I have put x as long to avoid integer overflow.
checks for n is positive etc. to be added.
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.

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.
Here is a simple FORTRAN code to calculate the factorial of a given non-negative integer: program factorial implicit none integer :: n, result print *, "Enter a non-negative integer:" read *, n result = 1 if (n < 0) then print *, "Factorial is not defined for negative numbers." else do i = 1, n result = result * i end do print *, "Factorial of", n, "is", result end if end program factorial This program prompts the user for an integer, checks if it's non-negative, and then calculates the factorial using a loop.
To create a program that calculates the factorial of a number using a function, you can define a recursive function or use an iterative approach. For example, in Python, you can define a function factorial(n) that returns 1 if n is 0 or 1, and calls itself with n-1 otherwise. Alternatively, you can use a loop to multiply the numbers from 1 to n. Here's a simple example using recursion: def factorial(n): if n == 0 or n == 1: return 1 else: return n * factorial(n - 1)
/*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); }
/*program to find the factorial of a given number*/ #include<stdio.h> #include<conio.h> int fact(int); void main() { int n,c; printf("\n enter the number for which you want to find the factorial"); scanf("%d",&n); c=fact(n); printf("\n the factorial of the number %d is %d",n,fact); getch(); } int fact(int n) { int k; if(n==0) return(1); else k=n*fact(n-1); return(k); }
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; }

Write a program using recursion which should take two values and display 1st value raised to the power of second value.
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.
