Recursion or Recursive Function

[Synapse]

hi everyone..i need help on the code below. i want to convert it to a recursive function. can anyone help me..pls! thanks a lot!:)

#include <iostream.h>
 
int main()
 
{
    int i, j;
    i=0;
    while (i<=4) {
        j=0;
        while (j<=4) {
           j++;
        }
        i++;
    }
    i++;
 
   cout << i*j;
}

What is the code doing right now? How do you think you'll implement a recursive algorithm to produce the same result?

i didn't get what you mean...actually i've created a function from the code above that has a return value. here it is:

#include <iostream.h>
#include <stdlib.h>

int product (void);

int main()
{
system("CLS");
int Ans;
Ans=product();
cout << "The answer is " << Ans << endl;
return 0;
}

int product (void)

{
int i, j;
i=0;
while (i<=4) {
j=0;
while (j<=4) {
j++;
}
i++;
}
i++;

return i*j;
}

Th output of this code is 30..
How will i convert this to a recursive function then?
