write a program to find the factorial of a number using function in c

#include<stdio.h>

#include<conio.h>

void main()

{

int factorial(int);

int n,fact;

clrscr();

printf("Enter the number: ");

scanf("%d",&n);

fact=factorial(n);

printf("%d!=%d",n,fact);

getch();

}

int factorial(int n)

{

int f=1,i;

for(i=1;i<=n;i++)

f=f*i;

return(f);

}

Output:

Enter the number: 3

3!=6
