Find the error

Question

#include<iostream.h>
void main()
{
int x,n,z;
cout<<"enter the value of x and n";
cin>>x,n;
z=pow(x,n);
cout<<"the value is"<<z;
}

Answer 1

cin>>x>>n;

Answer 2

Additionally to the point by Meet Mehta;

#include <iostream> no need for file extension .h

#include <cmath> is necessary for definition of pow()

int main() rather than void main()
