clrscr();
printf("\t Factorial Value Using Function:\n");
printf("\t *************************\n");
printf("\nInput:\n");
printf("\n---------\n");
printf("\nEnter the Number:\n");
scanf("%d",&n);
f=fact(n);
printf("\n Output:\n");
printf("\n --------\n");
printf("\n Factorial Value is:%d",f);
getch();
}
int fact(int n1)
{
int i,s=1;
for(i=1;i<=n;i++)
{
s=s*i;
}
return(s);
