Output is incorrect, am I missing the header ?

Asked By anonymous 7060 points N/A Posted on - 09/20/2011

Hi,

I'm using Visual Studio 2008, and please take a look at the code attached.

It doesn't compile correctly as it builds fails.

And the error message appears : error C2668: 'Pow' : ambiguous call to overloaded function. (I attached it)

Any idea what happens ?

Thanks

 

#include <iostream>

#include <cmath>

using namespace std;

 

 

int main ()

{

int N1;

cout<<"Enter the first number (a):";

cin>>N1;

int N2;

cout<<"Enter the second number (b):";

cin>>N2;

cout<<"a^b = ";

cout<<pow(N1 , N2)<<endl;

return 0;

}

I think there is a simple solution, try including math.h instead of cmath and make your "integers" doubles. Like: double n1; double n2; or float n1; float n2; I don't really remember how was the correct declaration in C…

Hello,

That’s pretty interesting.

First, use <cmath> and not <math.h>

Second, “pow” is not an integer rather it takes a floating point type number.

You can just try casting your statements.

Depending on what output you wish, there are a lot of reasons that the function may not work.

I would recommend visiting on this website for the different error codes related to programming –

That should resolve your issue.
