    Strang Error...

    Hey,

    I'm writing a simple program that finds the volume of a cylinder, but I keep getting a strange error message: 1>.\Volume.cpp(6) : error C2447: '{' : missing function header (old-style formal list?)

    Here's the code:

    Code:
    #include<iostream>
    
    using namespace std;
    
    int main ();
    {
    	int radius, height, volume;
    
    	cout << "Enter the radius..." << '\n' << endl;
    	cin >> radius;
    
    	cout << '\n' << "Enter the height..." << '\n' << endl;
    	cin >> height;
    
    	volume = 3.1415 * r * r * h;
    
    	cout << '\n' << "The volume is " << volume << endl;
    
    	return (0);
    }
    Hope someone can help...thanks.

    Code:
    int main ();
    You only use the semicolon when making function prototypes -- so the compiler thought you were declaring a prototype of int main, and then wondered what all this stuff was in the curly braces.
