C++ Algorithm Help

[HypeBeast McStreetwear]

Hi guys,

I'm and Engineer major which means I have to take this C++ class.

Long story short, I need help on our first assignment. I have to admit Im a complete N00B and I'm completely freaked out by this class.

Long story short, I have to modify this formula:

#include <iostream>
using namespace std;

int main()
{
double space, f0, f1;

f0 = 2e-10;
f1 = 2.0000004e-10;

speed = 6.685e8 * (f1 - f0) / (f1 + f0);
cout << "The speed is " << speed << " miles/hour " <<end1;

return 0;
}


To show the frequency a radar gun would recieve for a car going 55 mph.

I tried inputting this:

#include <iostream>
using namespace std;



int main()
{
double speed, f0, speed;

f0 = 2e-10;
speed = 55;

f1 = (-6.685e8 *f0 - speed * f0) / (speed - 6.685e8);
cout << "The frequency is " << f1 << " hertz " <<endl;

return 0;
}

But it keeps saying "Did you forget to include "stdafx.h" to the source file? I tried putting it in the source file but it doesn't work!

This implies that you're using Visual Studio. Go to Project->Properties and look for Precompiled Headers. Set it to not use precompiled headers. I'm not completely certain this will fix your problem, but I think it will.

Oh my god. Thanks! It worked!

I really appreciate it!

What you did was create a Win32 Console Application project. Microsoft can't resist helping out by adding Microsoft-specific goodies- like stdafx.h and properties like precompiled headers.

You can avoid this stdafx.h problem in the future by properly creating your projects.

You should:
1) Create a Win32 project (not a Win32 Console Application)
2) When the wizard appears do not click Finish.
3) Instead, click Application Settings
4) Select a) console application and b) empty project
5) Now click finish.
