What is the problem?

Question

#include <iostream>
using namespace std;
int pow(int a ,int b)

{
int p=1,i;
for(i=1;i<=b;i++)
p=p*a;
return p;
}
int f(int a,int b)
{
return pow(a,b)/pow(a+3*b,2);

}
int main() {
int a,b;
cin>>a>>b;

cout<<f(a,b);

return 0;
}

Answer 1

//so it should work

#include <iostream>
using namespace std;
int pow(int a ,int b)
{
int p=1,i;
for(i=1;i<=b;i++)
p=p*a;
return p;
}
double f(int a,int b)
{
return double(pow(a,b))/pow(a+3*b,2);
}
int main() {
int a,b;
cin>>a>>b;

cout<<f(a,b);
return 0;
}

Answer 2

There is no error ,answer is right
enter inputs like this way
5
6

Answer 3

add this to debug it and see the last result is 0.
for(i=1;i<=b;i++){
p=p*a;
cout << p <<endl;
}

what did you expect?
