Why one factorial and zero factorial is same?

As we know product of no numbers at all is 1 and for this reason factorial of zero =1and we know factorial of 1=1

Factorial in c program using for loop?

#include int main() { int fact,Factorial; printf("Please Enter Factorial Number\n"); scanf("%d",&fact); Factorial=func_fact(fact); printf("factorial is %d\n",Factorial); } int func_fact(int number) { int i; int factorial=1; for(i=number;i>=1;i--) { factorial=factorial*i; } return factorial; }


What is factorial of 0?

Factorial(0), or 0! = 1.


What is a factorial function in Visual Basic?

Factorial is a Mathematical Function.Factorial returns the product of all numbers from 1 to itselfe.g. Factorial 5 = 5*4*3*2*1 = 120It is expressed as n! = factorial of nTo implement it in Visual Basic, there are two methods-Function factorial(ByVal n as Integer) as IntegerIf n =< 1 Then factorial = 1:Exit Functionfactorial = n * factorial(n-1)End FunctionFunction factorial(ByVal n as Integer) as Integerfactorial = 1Dim a as IntegerFor a = 1 to nfactorial = factorial * aNext 'aEnd Function


How do you get factorial of a number?

You get the factorial by multiplying the number with every number before down to 1. Factorial of 3 would be 3! = 3 * 2 * 1 = 6 or the factorial of 5 would be 5! = 5 * 4 * 3 * 2 * 1 = 120.


C programming of factorial?

unsigned factorial (unsigned num) { return num &lt;2 ? 1 : num * factorial (num-1); }


Algorithm of factorial of a number?

Factorial (n) = n * Factorial (n-1) for all positive values n given Factorial (1) = Factorial (0) = 1. Pseudo-code: Function: factorial, f Argument: positive number, n IF n&lt;=1 THEN RETURN 1 ELSE RETURN n * f(n-1) END IF


Why factorial of 0 equals 1?

Zero factorial is one because n! = n-1! X n. For example: 4! = (4-1) X 4. If zero factorial was zero, that would mean 1! =(1-1) X 1 = 0 X 1=0. Then if 1!=0, then even 999! would equal zero. Therefore, zero factorial equals 1.


Why is n factorial equal to n factorial x n?

It is not except when n = 1.


What is the algorithm to find the factorial of given number?

For any positive integer, n, factorial (n) can be calculated as follows: - if n&lt;2, return 1. - otherwise, return n * factorial (n-1). The algorithm is recursive, where n&lt;2 represents the end-point. Thus for factorial (5) we find the following recursive steps: factorial (5) = 5 * factorial (4) factorial (4) = 4 * factorial (3) factorial (3) = 3 * factorial (2) factorial (2) = 2 * factorial (1) factorial (1) = 1 We've now reached the end-point (1 is less than 2) and the results can now filter back up through the recursions: factorial (2) = 2 * factorial (1) = 2 * 1 = 2 factorial (3) = 3 * factorial (2) = 3 * 2 = 6 factorial (4) = 4 * factorial (3) = 4 * 6 = 24 factorial (5) = 5 * factorial (4) = 5 * 24 = 120 Thus factorial (5) = 120. We can also use a non-recursive algorithm. The factorial of both 0 and 1 is 1 thus we know that the return value will always be at least 1. As such, we can initialise the return value with 1. Then we begin iterations; while 1&lt;n, multiply the return value by n and then subtract 1 from n. We can better represent this algorithm using pseudocode: Function: factorial (n), where n is an integer such that 0&lt;=n. Returns an integer, f. Let f = 1 Repeat while 1&lt;n Let f = f * n Let n = n - 1 End repeat Return f


Zero factorial equal to one factorial then if we cancel the factorials on both side then the answer becomes zero equals one. do u accepts this?

0!=1! 1=1 The factorial of 0 is 1, not 0

Is factorial like this 4x4-4-4?

No, that is nothing like a factorial. 4 factorial (written as 4!) is 4*3*2*1 = 24.

A Write a program that reads a nonnegative integer and computes and prints its factorial?

What value is equivalent to the following symbol 10!6!?

10! and 6! means factorial of 10, and factorial of 6, respectively. You can calculate that on most scientific calculators - or you can multiply all numbers from 1 to 6 for the factorial of 6, and all numbers from 1 to 10 for the factorial of 10.


Recursive definition and processes in c?

The factorial f(n) = n * (n-1) * (n-2) * .. 1. For example factorial 5 (written as 5!) = 5 x 4 x 3 x 2 x 1 = 120. The function below returns the factorial of the parameter n. int factorial( int n) { if (n==1) return 1 else return n* factorial( n-1) ; }
