Recursion

[jhykima]

Hello! I am currently trying to understand recursion and I am not quite sure why my code only prints "4"s. I am trying to understand what is going "under the hood." Any suggestions to clarify this?

void pow (int x, int y)
{
	if (y > 0)
	{
		pow (x, y - 1); 
	}
	cout << x << endl;
	x = x + 2; 
}

int main () 
{ 
	pow (2, 4); 
}

why my code only prints "4"s
did you mean, keeps printing only "2"s? if yes, it would because in each stack, the value of x is 2.

#include<iostream>
int pow(int base, int p)
{
if (p == 0)
return 1;
else
return base*pow(base, p - 1);
}
using namespace std;
void main()
{
int base=0, p=0;
cout << "Enter the base and power " << endl;
cin >> base >> p;
cout<<"The result is "<<pow(base, p)<<endl;

}
