Given with the number n the task is to calculate the factorial of a number. Factorial of a number is calculated by multiplying the number with its smallest or equal integer values.
Factorial is calculated as −
0! = 11! = 12! = 2X1 = 23! = 3X2X1 = 64! = 4X3X2X1= 245! = 5X4X3X2X1 = 120...N! = n * (n-1) * (n-2) * . . . . . . . . . .*1

There are multiple methods that can be used −
Through the loopsThrough recursion which is not at all effective Through a function
Given below is the implementation using functions
Algorithm
StartStep 1 -> Declare function to calculate factorial int factorial(int n) IF n = 0 return 1 End return n * factorial(n - 1)step 2 -> In main() Declare variable as int num = 10 Print factorial(num))Stop

使用C语言
例子
#include// function to find factorialint factorial(int n){ if (n == 0) return 1; return n * factorial(n - 1);}int main(){ int num = 10; printf("Factorial of %d is %d", num, factorial(num)); return 0;}
