C++ Visual Studios 2013
I keep getting the error error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'overloaded-function'. What do I need to do to fix this?

is this your whole code?
it works to me
<< isnt part of std namespace
it works to me
// Meaning you don't have to put std:: before cout <<; |
<< isnt part of std namespace

Hopefully what I say makes sense. So, on visual studios I have 3 source cpp files. They are ConsoleApplication2.cpp, stdafx.cpp, and circle.cpp. The one I just posted is circle.cpp. Whenever I compile circle.cpp on visual studios, it says this:

It looks like one of your later changes in code broke something: code you posted should work after correcting typo. Mind posting your current code?
#include "stdafx.h" // Precompiled header
#include "iostream" // Input and output stream
#include <cmath>
using namespace std; // Meaning you don't have to put std:: before cout <<;.
double calcArea();
double calcDiameter();
double calcCircumference();
pi = 3.14
double calcArea(double radius) {
double area;
area = pi * pow(radius, 2);
return area;
}
double calcDiameter(double radius) {
double diameter;
diameter = radius * 2;
return diameter;
}
double calcCircumference(double radius) {
double circumference;
circumference = 2 * pi * (radius * 2);
return circumference;
}
int main() {
cout << "Radius sizes for Area" << endl;
cout << calcArea(10) << endl;
cout << calcArea(12.5) << endl;
cout << calcArea(1.03) << endl;
cout << "Radius sizes for Diameter" << endl;

Use code button ( <> ) to properly format your code.
Problem is here:
It looks like you are declaring a variable, but all variables should have a type, which you did not provide.
fix:
Problem is here:
pi = 3.14It looks like you are declaring a variable, but all variables should have a type, which you did not provide.
fix:
const double pi = 3.14159265358;, or, if you are using C++11 like you should constexpr double pi = 3.14159265358;
Thanks so much! It compiles great, but there is a output display on visual studios 2013. Like it appears, and then dissappears so fast that I cannot even see my executable display. Any suggestions?
