Hey guys, can anyone help me with my C++ Assignment? It's very simple.
I'm nearly done, but something's fundamentally not working.

What's your output? I don't really want to run this code. Not that it looks unsafe but I'm worried about what I'm going to have to sift through as far as the text the console returns. It's not hard, it just gives me headaches sometimes.

So far I can only see that maybe you're using capital letters for variable names and possibly that the
>ifstream myfile
line isn't treating the myfile as a call to the constructor because of the white space between your variable name and the paren. But that could just be because I'm an idiot.

The output is just a text file that has some info on it. assignment_v4 has the complete list.

I mean your actual output in the console noob.

When you run your file or attempt to, what does it spit out to make you think that your program isn't running properly?

char numbers[20];
double Length;
double Width;
double Area;
double TotalWidth;
double TotalLength;
double TotalPerimeter;
double TotalArea;
double Radius;
double AreaC;
double Perimeter;
double Circumference;
double TotalAreaC;
double TotalRadius;
double TotalCircumference;
int Age;
int TotalAge;
int Savings;
int TotalSavings;
int Persons;
Persons=0;
Length=0;
Width=0;
Area=0;
TotalWidth=0;
TotalLength=0;
TotalPerimeter=0;
TotalArea=0;
Radius=0;
AreaC=0;
Perimeter=0;
Circumference=0;
TotalAreaC=0;
TotalRadius=0;
TotalCircumference=0;
It's no longer 1989 fucker, initialize the data WITH the declaration:

double Length=0, Width=0, Area=0,
TotalWidth=0, TotalLength=0, TotalPerimeter=0, TotalArea=0, Radius=0, AreaC=0, Perimeter=0, Circumference=0, TotalAreaC=0, TotalRadius=0, TotalCircumference=0;
int Age, TotalAge = 0, Savings, TotalSavings=0, Persons=0;

>#define M_PI 3.14159265358979323846

const double M_PI = 3.14159265358979323846;

Never use #defines

The console appears with nothing in it. Just sits there and doesn't close.
The only thing going wrong is the lack of an output.txt file.

your while loop is all fucked up, start there
usually you want to use getline

You have an infinite loop. To clear it use the condition myfile>>numbers instead.

This will pass a value, if there is one, into the numbers var and return true. When it runs out will return a false value.

You don't need getline, don't worry about that right now.

OP, you might want to look into formatting your code so it looks more aesthetically pleasing. I know it sounds gay as fuck, but it helps when others are looking at your code. Nice looking code is nice to read.
