char *str,select;
main()
{
int item;
do
{
clrscr();
printf("1. FACTORIAL\n");
printf("2. FIBONACCI\n");
printf("3. EUCLID\n");
printf("4. EXIT\n");
printf("SELECT AN OPTION:\n");
scanf("%d",&item);
if (item==1)
{
clrscr();
{
long a,b,c;
gotoxy(1,1);
printf("RECURSIVE\n");
printf("Enter a Number: ");
scanf("%li",&a);

}
getch();
}
else if (item==2)
{ clrscr();
{
