C Programming Factorial Function Code Example

Example 1: factorial c program using for loop

#include<stdio.h> int main(){   int i,f=1,num;     printf("Enter a number: ");   scanf("%d",&num);     for(i=1;i<=num;i++)       f=f*i;     printf("Factorial of %d is: %d",num,f);   return 0; }

Example 2: factorial of a given number in c

//Factorial of a given number #include <stdio.h>  //This function returns factorial of the number passed to it  long int factorialOf(int number){     long int factorial = 1;     while(number){         factorial*=number;         number-=1;     }     return factorial; }  int main(void) { 	int n; 	printf("Find factorial of \n"); 	scanf("%d",&n); 	printf("\nThe factorial of %d is %ld",n,factorialOf(n)); 	return 0; }
