vc源程序，怎么老是编译不通过，小弟不才，请诸位高手指点。

#include<iostream.h>
double power(double x,int n);

int main()
{
cout<<"5 to the power 2 is"<<power(5,2)<<endl;
return 0;
}
double power(double x,int n);
{
double val=1.0;
while (n--)
val*=x;
return (val)
}

Answer 1

#include<iostream>
using namespace std;

double power(double x,int n);

int main()
{
cout<<"5 to the power 2 is"<<power(5,2)<<endl;
return 0;
}
double power(double x,int n)
{
double val=1.0;
while (n--)
val*=x;
return (val);
}
