recursion
when i use this code i get answer that is always a raised to b+1.
why is that? when i put else statement in my power function i get the right answer? pls explain
#include <iostream>
using namespace std;
int power(int a,int b)
{
if (b>0)
{
return (a*power(a,(b-1)));
}
}
int main()
{int a,b;
cout<<"for a raised to b";
cin>>a>>b;
cout<<power(a,b);
}
why is that? when i put else statement in my power function i get the right answer? pls explain
#include <iostream>
using namespace std;
int power(int a,int b)
{
if (b>0)
{
return (a*power(a,(b-1)));
}
}
int main()
{int a,b;
cout<<"for a raised to b";
cin>>a>>b;
cout<<power(a,b);
}
Doesn't your compiler complain?
If (b>0) isn't true ... then your function doesn't return anything.
If (b>0) isn't true ... then your function doesn't return anything.
