Pointer conversion

[vetrivendhan]

void main()
{
int num,f;
clrscr();
printf("\nEnter a number: ");
scanf("%d",&num );
f=fact(num);
printf("\nFacto rial of %d is: %d",num,f);
getch();
}
int fact(int n)
{
if(n==1)
return 1;
else
return(n*fact(n-1));
}

How to implmnt d above progrma in C using pointer variablesss!!!? ?

What do you want to do with those pointer variables? btw, it's 'int main()' not 'void main()'.

kind regards,

Here is a pointer Variable implementation of your app:

int MyRecursiveFunction(int n);

int (*fact)(int) = MyRecursiveFunction;

void main()
{
int num,f;
clrscr();
printf("\nEnter a number: ");
scanf("%d",&num);
f=fact(num);
printf("\nFactorial of %d is: %d",num,f);
getch();
}
int MyRecursiveFunction(int n)
{
if(n==1)
return 1;
else
return(n*fact(n-1));
}
