factorial without recursion and with recursion || c language

 factorial without recursion in c language:

 

#include<stdio.h>

int main()
{
int  i,number ,fact=1;
    printf("enter a number\n");
    scanf("%d",&number);
    for(i=1;i<=number;++i){
    fact=i*fact;
    printf("factorial is %d\n\n:",fact);
    }return 0;
}

factorial with recursion:

#include<stdio.h>
int factorial(int n);
int main()
{
    int n;
    printf("enter n:");
    scanf("%d",&n);
    printf("factorial is :%d", factorial (n));
    return 0;  
}
int factorial (int n){
if(n==0){
    return 1;
}
int factnm1=factorial(n-1);
int factn = factnm1*n;
return factn;
}
