Obama managed a tech reference to compilers in a speech which was unusually non-crap for a non-techie:

She saw beyond the boundaries of the possible and invented the first compiler, which allowed programs to be written in regular language and then translated for computers to understand.

Which is just about the most elegant way to describe a compiler to a non-techie. Even the phrase "regular language" was cleverly chosen to have a double meaning, for techies vs non-techies.

Oh god, what am I doing...

The first thing you want to do is find those repeated sections which only have minor differences, and turn them into a function. The nested switches seem questionable there.

One thing that can really help is to define some constants e.g.

int dirNorth = 1;
int dirSouth = 2;
int dirWest = 4;
int dirEast = 8;

Then, instead of writing "case 13:" you write "case dirEast + dirWest + dirNorth:"
Doing something like that makes it easier read, and to see where you can turn parts of the code can be turned into functions by passing different "dir" values to the function.

Yeah, I need to make a function to rotate the points that I need, then I can simplify things a lot.

I think it'd be cleaner still to binary OR those values instead of using addition.

This is what I ended up with:

Code: [Select]

    [Flags]
    enum Directions
    {
        None = 0,
        NorthWest = 1,
        NorthEast = 2,
        SouthWest = 4,
        SouthEast = 8,

        North = NorthWest | NorthEast,
        South = SouthWest | SouthEast,
        East = NorthEast | SouthEast,
        West = NorthWest | SouthWest,

        All = NorthWest | NorthEast | SouthWest | SouthEast
    }

Maybe if you made the cardinals the single-bits the whole thing would be less complex? That's just a hunch I have. The good part is that by turning everything into variables, it's a lot less complex to try the other pattern.

[Rose]

I have 4 inputs, and they're all diagonals. The cardinals are only shortcuts to simplify things.

wh... why is input only diagonals? Is this something in isometric view such that "up" corresponds to "northeast/northwest"?

how do I set up Visual Studio Code to compile C++ programs? Should I follow this process?

If so, I'm missing the vcvarsall.bat and the build.bat isn't being recognized as a batch file, presumably because of the missing vcvarsall.bat file.

[eerr]

Why on earth would you not use a top of the line IDE that you have presumably just installed?

[Rose]

Make a project.

Add your files to that project.

Then click compile in visual studio.

[Shadowlord]

Visual Studio Code is different.

My suggestion is to just get an IDE that isn't that one.

So helpful. Thanks.

Define a top of the line IDE then? From what I hear Visual Studio is good, but Visual Studio Professional and Visual Studio Enterprise cost money, Visual Studio Community will not actually finish the installing process on my computer, and Visual Studio Code appears to be shit.

I've been using Code::Blocks but I tried Visual Studio Code based on a recommendation of what's "good to be familiar with" -in this case Visual Studio IDEs- if I want to be "competitive" in the job market for programming.
