cout<< "give me a number: ";
double side;
cin>>side;
double volume = cube(side);
cout<<"A "<< side << "-foot cube has a volume of ";
cout << volume << " cubic feet.\n";

using namespace std;
for(int i = 0; i< n; i++)
cout << "cheers! ";
cout << endl;
}
double cube(double x)
{
return x*x*x;
}
实验结果：
cheers! cheers! cheers! cheers! cheers!
give me a number: 3
A 3-foot cube has a volume of 27 cubic feet.
cheers! cheers! cheers! cheers! cheers! cheers! cheers! cheers!
