Write a C program To Find the Factorial Of a Given Number (n>0) Using Pointers.

PROGRAM

#include<stdio.h>

void findFact(int,long int *);

int main()

{

    long int fact;

    int num1;

    printf("Enter a number:");

    scanf("%d",&num1);

    findFact(num1,&fact);

    printf("The factorial of %d is: %d\n",num1,fact);

    return 0;

}

void findFact(int n,long int *f)

{

    int i;

    *f=1;

    for(i=1;i<=n;i++)

    {

        *f=*f*i;

    }

}

output:-
