Write a program to calculate the factorial of a given number using function.

#include<stdio.h>

#include<conio.h>

int fact(int);

void main()

{

 int n,a;

 clrscr();

 printf("\nEnter any number: ");

 scanf("%d",&n);

 a=fact(n);

 printf("\n factorial= %d",a);

 getch();

 }

int fact(int n)

{

 int i,f=1;

 for(i=1;i<=n;i++)

 f=f*i;

 return f;

}
