Write a program to calculate the factorial of a given number using recursive 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)

{

 if(n<=1)

 return 1;

 else

 return(n*fact(n-1));

}
