Program to display factorial of a given number 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;
}
